Does the cycle of menstruation change after taking postinor? Menstruation after taking Postinor: when should you go, what if they are not there? What to do if your period has not come

Postinor is a drug that is used as a contraceptive in emergency situations after coitus has ended. The effectiveness of the medication is quite high, however, there are side effects. It includes a fairly large portion of the inducing hormones. In such a situation, it is worthwhile to take a responsible approach to considering how menstruation can behave after Postinor.

Postinor's action

If you nevertheless decide to use this drug, then first of all you should familiarize yourself with the principle of its action. To begin with, there are two main hormones that are inherent only to the fair sex: progesterone and estrogen. For a girl who has no health problems, they are in harmony with each other throughout the entire menstrual cycle.

The tablets contain levonorgestrel, the principle of which is similar to progesterone. It should be noted that its effect is almost 150 times stronger. In this regard, the possibility of a malfunction during menstruation after taking this drug cannot be ruled out. Levonorgestrel is capable of causing the following reactions of the reproductive system:

• Ovulation is delayed - the process of maturation of the egg is inhibited, as well as its release from the ovary;
• The hormonal surge often causes endometrial rejection;
• Spermatozoa that enter the reproductive system of a girl are deprived of their activity and ability to conceive.

Many people think that using this medication can cause miscarriage. This opinion is erroneous. If the fertilized egg has already attached to the wall of the uterus and the development process has begun, then pregnancy is inevitable, and Postinor in this case is useless. He is only able to prevent conception, but does not terminate the pregnancy.

What is the effect of the drug on the course of the menstrual cycle? If Postinor acted at the right time, then the woman can only wait for the onset of planned menstruation. If menstruation went after the medication, then the pregnancy was successfully prevented.

Admission rules

The drug is indicated for use only when you have certain reasons to fear premature pregnancy, or more precisely, after unprotected intercourse. It is recommended to take Postinor according to the following method:

• No more than 24 hours after intercourse. In this case, the chance of success is close to 95%.
• Within two days after "dangerous" sex. It works in about 85% of cases.
• Two to three days after coitus. In this case, the contraceptive effect drops to 58%.

In order to prevent unwanted pregnancy, you will need 2 tablets of the medication. One of them is drunk within the above mentioned terms, and the other - after 12 hours. It should be understood that if time was lost, the use of the tool may be meaningless.

Before you start using Postinor, you should carefully study the instructions, namely the sections "Contraindications" and "Side effects". Having considered them in more detail, it will be possible to come to the conclusion that Postinor can be used during menstruation, but the manifestation of side effects, in particular such as or more, is not excluded.

Indications and contraindications

As mentioned above, the only indication for the use of this drug is emergency contraception. Drinking Postinor is contraindicated in the following cases:

• Allergy or hypersensitivity to the components of the medication;
• Application under the age of 16;
• Severe liver failure;
• During pregnancy;
• Lactose intolerance;
• Glucose-galactose malabsorption;
• Lactase deficiency.

In addition, you should take the drug with caution if you have various types of liver or biliary tract diseases, as well as with jaundice, lactation and Crohn's disease.

Among the main side effects, the following are worth noting:

• Allergic reactions: rash, swelling, urticaria, itching;
• Vomit;
• Diarrhea;
• Dizziness;
• Violation of menstruation;
• Headache;
• Fatigue;
• Nausea;
• Hemorrhage.

In case of an overdose, there may be an increase in the severity of side effects.

When should your period go?

Ladies who have taken this medication always ask the following question: when should menstruation go after Postinor? There is no definite answer, since this is all individual. First of all, it depends on the girl's personal hormonal background, as well as on when the pills were taken. An equally important factor is the stage of the menstrual cycle when using the drug.

So can the cycle get lost after using the Postinor contraceptive? Obviously yes. Unfortunately, not one of the doctors will be able to tell you exactly how long to wait for the start of the menstrual cycle, as well as whether the period will go ahead of schedule or later. If it does start, you should contact a specialist. If the delay is more than 5 days, then this is also a cause for concern.

In most cases, after the medication, the menstrual cycle begins a little earlier. This is because levonorgestrel affects the latter, and this is normal. It is also possible that Postinor's reception may not affect the course of menstruation. However, one should not exclude the possibility of delaying the cycle after using emergency contraceptives.

If you came earlier

What is evidenced by the fact when, after using the drug, menstruation came ahead of time? Quite often, women notice that a week after Postiron, menstruation begins. This is primarily due to the effect of levonorgestrel on the second phase, which, as a result, becomes shorter.

Some women suggest that the use of Postinor promotes the resumption of menstruation. And indeed it is. If pregnancy has not occurred, then most often in this case, menstruation resumes.

Possible reasons for the delay

A delay after Postinor is observed in many cases. Because levonorgestrel is a potent substance, there can be unpredictable effects on a woman's body. There are several main ones after taking Postinor:

• The timing of taking the medication was ignored. Pregnancy is possible;
• Increased blood clotting. Vessels are unable to release blood outside;
• Alcohol was consumed while the drug was active;
• In parallel, other medications were used, which may be the reason for the neutralization of the contraceptive effect;
• Hormonal disbalance;
• Diseases of a gynecological nature, as well as endocrine abnormalities;
• The delay in menstruation after Postinor occurs due to special contraindications.

Even if all the above-mentioned reasons for the delay are excluded, and menstruation still does not start, then you should not postpone the trip to the doctor. The possibility of an ectopic pregnancy, which is very difficult to diagnose on your own, is not excluded.

In addition, adolescent girls often resort to taking this drug, as they disdain the means of contraception in the form of condoms. Therefore, the delay occurs as a result of changes in the hormonal background of young women. General malaise is also observed.

Complete absence of menstruation

Often, Postinor causes hormonal imbalance, which can lead to a serious disruption of the cycle, as well as to. What if after Postinor your period didn't go? In this case, you should immediately consult a doctor.

The following problems are most often diagnosed:

• Disorder of the correct functioning of the ovaries. Recovery usually takes about three months;
• Ovarian dysfunction, in which they cannot cope with intermittent doses of levonorgestrel. The consequences can be dire - up to infertility;
• Failure of hormone secretion, which can lead to the inability to conceive.

These are not all the reasons why menstruation does not come. There are many other factors and risks that directly depend on the specific situation. If after taking Postinor there are no periods, seek professional help.

• Taking certain groups of vitamins;
• Use of homeostatic drugs;
• Proper nutrition.

Initially, this drug is considered completely safe for, but only if the woman has no contraindications and health problems. Despite this, it is not suitable for everyone and it is better to think a hundred times over whether it is worth using it as a contraceptive or abstaining.

Other difficulties after taking Postinor

After Postinor, menstruation can change their character, and changes in volume are also observed. In addition, there are a number of other complications associated with taking this medication. A woman who has blood clotting problems may develop blood clots. As a result of the blockage of the vessels of the heart and brain, the development of a stroke or instant death is not excluded.

As a rule, if a girl does not have problems with the menstrual cycle, side effects of the drug are rare. You may also experience the following symptoms:

• Painful sensations in the lower abdomen;
• Nausea;
• Diarrhea;
• Headache;
• Swelling.

The nature of menstruation

Menstruation after Postinor can dramatically change its character. This is directly related to the effect of the main active ingredient of the drug. The change in the nature of menstruation is explained by a change in the hormonal balance of the woman's body. In some cases, changes can propagate over multiple cycles. In this case, you need to seek help from a specialist, since this medication is considered heavy.

They are the reason that, as a result of the effect of the drug, the frequency of contractions of the walls of the uterus during menstruation increases. Since not every girl can experience an increase in clotting, bleeding can stop only after a while. In addition, the risk of uterine bleeding is not excluded against the background of a malfunction of the hormonal background.

Painful periods () are abnormal. In this case, you should immediately consult a doctor. As a consequence of the greater loss of blood during menstrual flow, anemia may develop, which is characterized by the following symptoms:

• Severe weakness;
• "Flies" before the eyes;
• Cardiopalmus;
• Dizziness;
• Loss of consciousness.

In order to use traditional medicine. The most effective is a decoction of nettle. In addition to nettle, you can use mint, rowan berries and the following herbs: yarrow, shepherd's purse, peppermint. If folk remedies do not give the desired effect, sodium ethamsylate can be used. However, this medication can only be taken after consulting a doctor.

Also, quite often, after using Postinor tablets, women complain that. In some cases, this may appear as a "brown daub". This situation is considered a frequent occurrence after the use of such drugs. Himself and their scarcity is explained by increased blood coagulability.

How to restore the cycle

Is it possible after using Postinor ?. The answer is unequivocal - yes. So what needs to be done in order to restore the course of the menstrual cycle? Here are some of the doctors' recommendations:

• If you notice any changes in the functioning of your body after using this medication, consult a specialist. Take care of your health and do not run the situation;
• In order to restore the cycle after using the pills, you will need to undergo a set of examinations to make sure that nothing threatens your body;
• Do not use this type of medication too often. If initially they did not affect your body in any way, this does not mean at all that this will continue in the future.

Postinor is a postcoital contraceptive drug. It is taken as prescribed by a doctor. This is necessary, first of all, in order to avoid side effects of the drug, including menstrual irregularities. With the correct, in accordance with the instructions, the use of postinor, such violations, if they happen, are transient.

Drug action

Postinor contains levonorgestrel, a synthetic analogue of the female sex hormone progesterone. This hormone is contained in postinor in a very high concentration, which makes it possible with a high degree of probability to prevent a possible pregnancy.

If there is a lot of progesterone or its synthetic analogs (progestogens) in the blood, this suppresses the action of the female sex hormones estrogens and the secretion of gonadotropic hormones of the pituitary gland. As a result, if the reception of postinor coincides with the first half of the menstrual cycle, the maturation of the egg and its release from the ovary (ovulation) is suppressed, and without the egg, pregnancy cannot occur. At the same time, the proliferation of the mucous membrane of the uterine cavity (endometrium) is suppressed.

If the reception of postinor occurs in the second half of the menstrual cycle, it will also lead to the impossibility of pregnancy, since under the action of this drug the endometrium becomes unsuitable for implantation of a fertilized egg.

Causes of violation of the monthly cycle

In most cases, a one-time intake of large doses of hormones does not affect a woman's menstrual cycle in any way. But in some cases it still happens. Most often, some changes on the part of menstruation develop in women who already have menstrual irregularities. That is why it is necessary to consult a doctor before taking postinor.

But most often, menstrual irregularities after taking postinor occur with its frequent use, sometimes several times in one menstrual cycle, although this is not recommended by the drug manufacturers. In this case, especially if the woman already has some kind of violations in this area, the postinor can cause persistent violations that will later become the basis of infertility.

Uterine bleeding

Large doses of gestagens can cause suppression of the ovaries' own secretion of progesterone and suppression of the secretion of pituitary hormones. And since after a while the gestagens are removed from the body and hormonal support for the development of the endometrium falls, the mucous membrane of the uterine cavity is rejected, which causes menstrual bleeding. This bleeding can be very severe and will require emergency medical attention.

Sometimes menstruation simply becomes longer and more abundant, intermenstrual bleeding appears - all these are signs of hormonal imbalance. ... But with the correct use of postinor, this happens very rarely and gradually the woman's menstrual cycle is restored.

Frequent use of postinor can lead to the development of severe bleeding, followed by the formation of iron deficiency anemia. - a condition that is not so easy to cure.

Lean, no, or painful periods

Such violations, with the correct application of postinor, are even less common than bleeding. They say that the woman, of course, had some kind of mild ovarian dysfunction, which she did not pay attention to. Therefore, the manufacturer recommends prescribing postinor with a regular menstrual cycle. After a single dose of postinor, such irregularities usually disappear within several menstrual cycles. If this does not happen, then you should see a doctor.

With frequent use of postinor, ovarian function can be significantly impaired, which usually manifests itself in the form of oligomenorrhea (scanty periods), amenorrhea (absence of menstruation) and dysmenorrhea (painful periods). If you consult a doctor in time, it is possible to restore the menstrual cycle. But long-term violations of this kind can lead to the formation of persistent infertility.

Hormonal disorders can be associated with insufficient secretion of female sex hormones by the ovaries, as well as with a violation of the secretion of gonadotropic hormones of the pituitary gland, which will lead to impaired maturation of the egg and the absence of ovulation - the release of an egg without an ovary. Without an egg, the onset of the desired pregnancy in the future is impossible.

Prolonged menstrual irregularities can lead to severe, difficult to treat infertility. Therefore, if persistent menstrual irregularities appear after taking postinor, you should consult a doctor.

Postinor is an effective and fairly safe postcoital contraceptive, but only if the recommendations set out in the instructions are followed during its use.

Dear women, I have a question for you. From 14 to 15 there was a slight embarrassment, the condom slipped. I understand, a very stupid situation. As a result, my (in light of unexpected circumstances not related to the events described), a former young man on the 29th promised to buy a test, just in case. Within 48 hours after that night, and took Postinor. The instructions say that a delay is possible, but menstruation began two weeks after the last (ended on the 8th, started today). Plus drowsiness, some dizziness, nipples hurt, a strange dry forest, and in general, a general malaise is felt. Maybe I'm in vain panicking about pregnancy, and it's worth going to the doctor only because of the strange displacements of the cycle?

WAR
Because of Postinor, the cycle may shift. And how much did Postinor drink?

ramono4ka
Bleeding after Postinor is considered normal. It usually occurs within a week or two after taking the drug. I had it in a week. The next menstruation began with a normal cycle, but with a countdown from this bleeding. The nipples hurt, too, and quite badly - all this is a consequence of hormonal imbalance. I can add from myself that now from Postinor (3 years have passed) I received as a "gift" a terrible PMS (pain in the chest and lower abdomen 5 days before the menstrual cycle), which cannot be cured by anything. And what will happen in the future with conception is unknown.

WAR
Are you sure it's from Postinor? I have never drunk Postinor in my life, but I also have PMS.

ma-tresh-ka
In fact, Postinor is such a strong hormonal shock that it could well "give" PMS. Moreover, if before taking PMS they did not suffer. jeanne-hebuterne, just not after 2 weeks you started, but more. The cycle is considered not from the end of the previous menstruation, but from its beginning. Those. On the 8th it ended, but when did it start? Well, yes, Postinor can noticeably knock down the cycle.

jeanne-hebuterne
WAR, as per instructions - 2 tablets in 12 hours.
ramono4ka, I see. Well, until now, PMS, in principle, has not manifested itself at all. So let's see what happens now.
ma-tresh-ka, and started on the second.
Well, well, we'll buy a test at the weekend, we'll find out. And then "dad" already began to wind me up yesterday, not just two, but all three strips he promised.

baobab
Postinor is a very big hormonal stress. It is necessary to remember the consequences, although in such extreme cases, Postinor is better than abortion. Unfortunately, there is still no one hundred percent guarantee. I have a nephew, conceived on Postinor.

jeanne-hebuterne

For me now, a child is completely early and unexpected ... so I had to take such emergency measures. Of course, it would be a sin to take it ... but the phrase "to die and not to be born are two different things". I’m thinking, and if the test can also be mistaken ... for sure it will be even better to donate blood, what do you think? At such moments, alas, there is no strong trust in technology ... and blood will show 100%.

It has long been proven that none of the types of contraception used will give one hundred percent protection against unwanted pregnancy: a condom can rupture, and not a pill taken on time, lead to conception.

Postinor - an emergency contraceptive drug

If the likelihood of getting pregnant is high, then in the first three days after unprotected intercourse, you can use the drug Postinor. It belongs to the group of emergency contraception. Its main purpose is to start menstruation. But the question often arises when menstruation will come after Postinor. Let's try to figure it out.

About the drug

Many are familiar with this drug firsthand. It prevents unwanted pregnancies and is a contraceptive. It is based on the hormone levonorgestrel. Postinor does not belong to the group of oral contraceptives that must be taken daily. This is a drug that can help in some emergency situations. An example is the case when a condom bursts at the most inopportune moment.

One tablet of the drug contains almost twice as much levonorgestrel than the body normally produces. Less of it is also found in oral contraceptives for daily use. According to the instructions, you need to take two tablets within twelve hours. A larger amount of drug intake at a time will not affect the final result, but it can easily lead to hospitalization.

Postinor's action is based on the fact that the body accumulates a large amount of gestagen after its use. It is able to slow down the ovulation process and lead to corresponding changes in the layer of the endometrium of the uterus. After using the drug, the attachment of a fertilized egg in the uterus is also impossible. The time of the arrival of menstruation is influenced by the phase of the cycle in which the tablets were used.

In the case of intercourse in the first half of the menstrual cycle, taking Postinor will have a blocking effect on the ovulation process, which will prevent conception. In the second half of the cycle, the action will be associated with a change in the lining of the uterus, which will make the attachment of the egg impossible. In the first case, the action is associated with a decrease in the synthesis of estrogens, in the second - with a decrease in progesterone and luteinizing hormone.

Under the influence of levonorgestrel, mucus in the cervical region becomes viscous and does not allow sperm to pass through. The probability of conception drops several times. For the greatest effectiveness, the drug should be taken immediately after unprotected intercourse or in an unforeseen event. In advance, before the planned sex, it is not recommended to perform such procedures.

Postinor does not allow the fertilized egg to gain a foothold in the uterus

Correct application

The tablets must be drunk no later than seventy-two hours after intercourse with sperm outflow, if pregnancy is not planned. Two tablets must be taken with a gap of at least twelve hours and no more than sixteen. It is on how quickly they were drunk that the result of the onset of menstruation depends. Statistics show that conception will occur with a probability:

• 5% - if you use the drug after twenty four hours;
• 15% - if from twenty four to forty eight hours have passed;
• 42% - if you take pills after forty-eight hours.

When a woman does not have serious problems in the genital area, then the arrival of menstruation after taking the drug is not delayed, they come on time. If they come one or two days later or earlier, then there is no cause for concern. If they are delayed for five days or more, there is a reason to conduct a pregnancy test or contact a gynecologist.

It is especially important not to forget that Postinor is approved for use at the age of sixteen and older. It is not recommended for the category of women who have a strong hormonal imbalance.

You should not take Postinor more often than once a month. And it is worth remembering that if the implantation of the embryo has already taken place, then this drug will not help here.

Over time, the effectiveness of the drug decreases

In case of delay

Postinor, according to the instructions, leads to a malfunction of the menstrual cycle. Menses come one, two days later or earlier than usual after using the drug. The next menstruation is also shifted by this period. The result of taking the pills is a mild spotting that lasts one or two days and resembles a period. They can be repeated once more in one cycle.

There may be several reasons for the late onset of menstruation:

• pregnancy;
• failure in the hormonal system;
• lack of a regular menstrual cycle;
• infections in the genital area;
• allergy to the drug.

Ovarian dysfunction is restored within two or three cycles. If the fourth and fifth menstruation came late or did not come at all, then consultation with a specialist is required. With frequent use of Postinor, the ovaries may not cope with their intended purpose. Infertility can be the result.

Only a doctor can help with pregnancy. The only thing that can be done at home is to carry out a pregnancy test. The final answer can be obtained after a gynecological examination and passing the hCG test. If the results are positive, then there is no cause for concern in terms of the full development of the child. Postinor does not have a negative effect on the fetus and its full development.

Before using Postinor, you should take a pregnancy test

Possible deviations

If a woman has an irregular menstrual cycle, hormonal disruptions, then some deviations are possible as a result of Postinor's use for emergency contraception.

These include:

1. Profuse bleeding. It is the result of a powerful dose of gestagens entering the body, which causes a decrease in the level of progesterone and pituitary hormones. The rejection of the mucous membrane in the uterus becomes the result of hormonal changes, and bleeding occurs, which cannot be stopped on its own. If a woman changes two pads within three hours, then there is a reason to see a doctor.
2. An increase in the duration and intensity of spotting. This problem is typical for women with disruptions in the hormonal system. That is why it is not recommended to take this drug for this category of women.
3. Iron-deficiency anemia. It occurs as a result of profuse bleeding.
4. Painful and scanty periods. This deviation is quite rare.
5. Interruptions in the menstrual cycle. They arise in response to interruptions in the work of the pituitary gland or ovaries.
6. Discharge brown. They are quite an adequate response to taking pills.
7. Increased blood clotting. It occurs with repeated administration of Postinor and threatens the formation of blood clots in the vessels, which can lead to a stroke or heart attack.

After taking the pills, vomiting, swelling and chest pain, headaches are possible. Emergency help should be sought if there is shortness of breath, difficulty breathing, swelling of the face, unbearable pain in the lower abdomen and repeated vomiting.

Particular attention should be paid to the use of the drug in women with fibroma and other tumors in the gynecological area. Taking Postinor is also not recommended for those who smoke.

Postinor is recognized as a completely safe contraceptive that works well in unforeseen situations, if you follow the instructions correctly and do not abuse it. Treatment after its use is prescribed only in cases where menstruation is delayed or does not come. And only when, after a thorough examination, the final cause is revealed.

Blood clotting when using Postinor can dramatically increase

You should know

Postinor is a medication with its own contraindications and side effects. Therefore, its reception is accompanied by various rules and features that you need to know:

• in case of vomiting within three hours after taking any of the two Postinor tablets, you can take one more tablet additionally, but only after consulting a gynecologist;
• after using the drug before the start of the next menstruation, it is necessary to take additional measures for protection, such as condoms;
• during lactation, with Crohn's disease, liver and biliary tract diseases, Postinor should be used with special care;
• in case of side effects in the form of a rash, swelling and itching, antihistamines may be taken, but only after consulting a doctor;
• Postinor is contraindicated in women with severe renal failure, lactose deficiency and glucose-galactose malabsorption;
• do not forget about age less than sixteen years and pregnancy, when taking pills is strictly prohibited;
• Postinor affects the intake of anticoagulants and drugs for glycemia, reducing their effect;
• the effectiveness of the drug can be reduced: tretinoin, barbiturates, nevirapine, oxcarbazepine, ampecavil, lansoprazole, tacrolimus.

When there is an urgent need to use Postinor in girls under sixteen years old (in the case of rape), then the issue can be resolved positively on an individual basis by a gynecologist.

Only the correct adherence to all the rules for using the drug, which are prescribed in the instructions, will help from side effects and adverse consequences. You should never rely on the internet or magazine articles. In the case of using emergency contraceptives, the main help will be provided only by a competent specialist, with whom you can consult in advance, knowing about the intended sexual intercourse. He will accurately determine possible contraindications for taking pills.

Menstruation after using Postinor is a clear proof of its effectiveness. But one of the main questions remains the one, the answer to which will be the period of onset of menstruation after taking the pills. As always, everything is individual and largely depends on the state of health in the woman's genital area. This drug has been tried on themselves by thousands of women, whom it helped to avoid conception. But do not forget that such pills are not one hundred percent safe and should be used only in exceptional cases, when there is no other choice.

All emergency contraception leads to irregularities in the menstrual cycle. Postinor is no exception. High levels of levonorgestrel can have powerful negative effects on the body and lead to negative consequences even after a single dose. You should never forget about the likelihood of infertility in case of drug abuse. Therefore, Postinor should not be considered a magic remedy for unwanted pregnancy and its use should not be abused.

Postinor refers to emergency contraception. The tablets are taken after unprotected intercourse in order to prevent unwanted pregnancy up to three days after it, otherwise there will be no result.

The effect of the contraceptive is based on a sharp increase after taking the concentration of estrogens and progestogen in the blood due to the hormone levonorgestrel, which is part of the composition. If critical days have come after the drug, then pregnancy has not occurred.

In 60% of cases, women notice a delay of up to 1 week, and the discharge itself lasts 2-3 days less than usual. Periods may vary: to acquire, the amount of excreted blood will decrease or appear. Sometimes discharge in the middle of the cycle with pain in the lower abdomen is possible. With repeated use, the drug can provoke a violation of the cycle and heavy bleeding during menstruation.

Your period usually starts a few days after you take the second pill., drunk in the second phase of the cycle, but the specific time of their appearance depends on the individual characteristics of the organism. They can last from three days to a week. After taking Postinor, women who have given birth may have their periods longer than those who have not yet had a pregnancy.

Possible reasons for the delay: non-observance of the instructions for admission, pregnancy, an increase in blood viscosity, the use of alcoholic beverages along with the drug, the simultaneous intake of another agent that neutralizes Postinor, hormonal failure, thyroid disorders and gynecological diseases, ectopic pregnancy.

A few days earlier before the expected period, menstruation may also begin, this is due to the action of the hormones contained in the drug. Instead of the usual bleeding, there is a scanty brownish or bloody discharge that can last much longer than usual.

You need to see a doctor if:

• appear instead of normal menstruation.
• The duration of menstruation is up to 10 days, and the intensity does not decrease.
• With discharge, weakness, dizziness and pain in the lower abdomen are observed, especially if the sanitary napkin needs to be changed every 2-3 hours.
• The discharge intensifies at night, there are a large number of clots.

Postinor's action

The effect of this contraceptive is based on a sharp increase after ingestion of the concentration of estrogens and progestogen in the blood. The main active ingredient of Postinor, the synthetic hormone levonorgestrel, is contained in a minimum dosage in many other oral hormonal contraceptives.

The action of the drug has a triple focus, depending on which phase of the menstrual cycle it is taken:

• in the period before ovulation, Postinor can delay the start of the process of release of the egg from the follicle or stop it;
• after ovulation, under the influence of hormones, mucus is compacted in the cervical canal, due to which sperm cannot penetrate into the uterine cavity;
• the uterine endometrium changes its structure, as a result of which the ovum cannot gain a foothold on the wall of the uterus, which in fact is an abortion.

For full contraception, two Postinor tablets are taken. The first should be drunk as soon as possible after intercourse, and the second after 12 hours. If the drug is taken later than three days after unprotected sexual contact, there will be no contraceptive effect.

Expert opinion

It must be borne in mind that taking Postinor dramatically changes the hormonal balance, which can lead to bleeding. Doctors recommend using such extreme contraception no more than twice a year.

How are your periods after taking Postinor

Since this drug causes a hormonal surge in the body, this cannot but affect the nature of menstruation. More than 60% of women who took Postinor as an emergency contraceptive measure report a delay of critical days for up to one week.

The failure of the menstrual cycle is insignificant, except in cases where there are any gynecological diseases.

After taking Postinor and other drugs of a similar effect, the intensity and color of the discharge during menstruation may change, this is manifested in the following:

In some cases, against the background of using Postinor, women may experience slight spotting in the middle of the menstrual cycle, accompanied by painful sensations in the lower abdomen.

How long will it take

Usually, menstruation begins a few days after taking the second pill, but the exact time of their appearance depends on the individual characteristics of the organism. If menstruation has not started, you should see your gynecologist, as this may be a sign that contraception has not worked and pregnancy has occurred.

The hormone, which is the basis of Postinor, actively acts on the receptors of the uterus, as a result of which its contraction and rejection of the endometrial layer begins. This process causes menstrual bleeding, which can last from three days to a week. In addition, the drug changes the properties of the blood, making it more viscous.

Increased blood clotting contributes to the formation of blood clots, which shorten the duration of critical days, therefore, if, without taking emergency contraceptives, menstruation, for example, lasts five days, then with their use, bleeding may stop after three days.

Possible reasons for the delay

In most cases, women note that after taking Postinor, critical days begin with some delay. This can happen for a variety of reasons:

• non-compliance with the instructions for taking the drug;
• fertilization of the egg and fixation of the ovum on the endometrium;
• an increase in blood viscosity due to increased coagulability;
• the use of alcoholic beverages while using the drug;
• the simultaneous use of other drugs, due to which the contraceptive effect of Postinor is neutralized;
• hormonal disruption resulting from repeated administration of the drug;
• use of the product if there are contraindications to it;
• some dysfunctions of the endocrine system and existing gynecological diseases.

Expert opinion

Daria Shirochina (obstetrician-gynecologist)

With a delay in menstruation after taking Postinor, it is imperative to seek advice from a gynecologist, since such a phenomenon may be the result of an ectopic pregnancy, which threatens a woman with serious consequences.

In some cases, a significant delay in menstruation and even their complete cessation occurs due to a significant hormonal imbalance. The most common causes of this phenomenon are:

• , which, when you stop taking the drug, can recover within three menstrual cycles;
• in more serious cases, dysfunction of the ovaries can lead to infertility;
• , in which the egg does not mature under the influence of a sharply increased concentration of certain hormones.

If you arrive ahead of time

Sometimes, against the background of Postinor's reception, critical days begin several days before the due time, which is due to the action of the hormones contained in the drug.

In the second phase of the menstrual cycle, progesterone is actively produced in the female body, which regulates the onset of menstruation. Since this hormone is one of the main components of the drug, the effect of progesterone is significantly enhanced, and the second phase of the cycle is shortened, as a result of which the critical days begin much earlier.

Some women use this property of the drug in order to cause menstruation if pregnancy is suspected, but doctors do not recommend using Postinor for this purpose, since this can lead to serious complications.

The nature of the discharge

Changes in the intensity and color of menstrual blood after taking emergency contraception occurs due to the fact that under the influence of hormones, there is no complete separation of the endometrium. At the same time, the nature of menstruation changes, and instead of the usual bleeding, scanty brownish or bloody discharge appears, which can last much longer than usual.

Seeing a doctor may be required for the following symptoms:

• Scanty brown discharge is characteristic of the menstrual cycle in which Postinor was used for contraception, this is the norm and should not cause alarm. However, if such discharge appears instead of normal menstruation, you should consult your doctor, as this may be a sign of various pathologies.
• The duration of menstruation is up to 10 days, this situation may require the appointment of hemostatic drugs.
• Intense discharge of blood, in which there is weakness, dizziness and pain in the lower abdomen. The danger is such bleeding, in which the sanitary napkin needs to be changed every 2-3 hours.

Excessive bleeding can be a sign of the development of neoplasms of various etiologies in the organs of the reproductive system, ectopic pregnancy, serious hormonal disorders or abortion.

To normalize hormonal levels after taking Postinor, the doctor may prescribe long-cycle oral contraceptives.

How much are normal

It is impossible to predict the exact duration of the critical days, since many factors affect this.

In most cases, menstruation in the menstrual cycle in which Postinor was used last 2-3 days less than usual. In the future, the nature and duration of bleeding is restored.

If long after Postinor

The duration of menstrual bleeding while taking the drug may be different, it depends on the individual characteristics of the female body. But, if scanty discharge and a shortened period of menstruation are in most cases the norm and do not require medical intervention, then a significant increase in the duration of critical days and the intensity of discharge can be a symptom of a serious pathology.

To determine the norm of the amount of discharge and their duration, the weight and height of the woman, as well as the number of previous births, are important. After taking Postinor, women who have given birth may have their periods longer than those who have not yet had a pregnancy.

The reason for a visit to the doctor is a situation when the critical days after using emergency contraception last more than ten days, and the intensity of bleeding does not decrease.

Also, consultation with a gynecologist is necessary for the following complaints:

• against the background of prolonged bleeding after taking Postinor, a woman has attacks of dizziness, shortness of breath, weakness;
• discharge intensifies at night, and several sanitary napkins have to be changed during the night;
• the presence of blood clots in the discharge.

Do I need to take the drug during menstruation

There is no prohibition on the use of Postinor at the beginning of the menstrual cycle, but the nature the next critical days directly depends on the phase in which the contraceptive was used.

Emergency methods of contraception can stop menstruation, which will lead to a subsequent violation of the cycle.

Conception can only occur after egg maturation, which occurs in the middle of the menstrual cycle, so it makes no sense to take emergency contraceptive pills during critical days.

It should be borne in mind that no contraceptive method gives a 100% guarantee against unwanted pregnancy. Postinor should be used only in exceptional cases and after a mandatory consultation with a gynecologist, since this remedy has many contraindications and side effects.

Doctors are ambivalent about the use of Postinor as a method of contraception. The drug has many side effects, first of all, it is a sharp change in hormonal levels, which can have unpleasant consequences for the female body.

Modern pharmacology offers a wide range of contraceptives, including hormonal ones, containing minimal doses of active substances and not causing harm. If for some reason a woman cannot use these means, it is better to use a condom to prevent unwanted pregnancy.

Hello!

The information that in the next few days after taking the drug "Postinor" the woman should start having her periods is not entirely correct. It is also not necessary to associate the contraceptive effect of the drug with this.

The drug "Postinor" refers to the methods of "emergency" contraception. The main active ingredient is levonorgestrel, or the synthetic hormone progestogen. Its mechanism of action is triple:

It causes inhibition of the ovulation process - in this case, the release of the egg from the ovary into the fallopian tube does not occur, thereby preventing the process of conception;

Increases the viscosity of cervical mucus, which prevents the advancement of sperm and therefore the fertilization of the egg;

Changes the normal structure of the inner surface of the uterus - endometrium and prevents the implantation of a fertilized egg.

The drug is recommended for women with a regular monthly cycle. Ideally, the use of "Postinor" should not cause changes in the menstrual cycle, and the following menstruation after taking the drug should come according to the woman's usual schedule. However, much depends on the individual characteristics of the woman's body, as well as on what phase of the menstrual cycle she was in when she took the drug. If Postinor was taken before ovulation, that is, in the first half of the cycle, there is a possibility of delayed menstruation. The delay should not exceed 3-5 days, otherwise pregnancy should be excluded.

Intermenstrual discharge and bleeding after taking the drug are more likely side effects, and are associated with a large load on the endocrine system.

The fact is that as a result of the use of "Postinor" in the blood, the level of the hormone progestogen sharply increases, which is responsible for the inner surface of the uterus and thickens the endometrium. Bleeding is most likely to occur if 2-3 postinor tablets are taken for a short time. In case of severe uterine bleeding, you should immediately consult a gynecologist.

Other manifestations of side effects are a feeling of tension in the mammary glands, pulling pains in the lower abdomen, nausea, dizziness, general weakness, fatigue.

The contraceptive effect of the drug, according to the instructions of its developers, depends on the time of administration and is assessed as follows:

95% of successful termination of an unwanted pregnancy - the drug was taken within 24 hours after the act;
85% of successful termination of unwanted pregnancy - the drug was taken within 25-48 hours after the act;
58% of successful termination of unwanted pregnancy - the drug was taken within 49-72 hours after the act.

On average, when using Postinor, unwanted pregnancy can be prevented in 85% of cases. The longer the interval between sexual intercourse and taking "Postinor", the lower the effectiveness of the drug. The drug is ineffective if the implantation of a fertilized egg has already taken place.

In the case of severe vomiting in the first two hours after taking the drug, its effect may not be sufficient to terminate the pregnancy.

Using "Postinor", one should not forget that this is an "emergency" measure, and you should not get carried away with it. Do not use the drug more than 1 time during the menstrual cycle.
