Postinor is a drug for early termination of pregnancy: instructions for use and possible consequences. Postinor - how to terminate an early pregnancy, side effects, consequences of Postinor during pregnancy, who took it

If the pregnancy is unplanned and at the wrong time, many women decide to terminate it because they are not ready or do not want to give birth to a child. If the period is short, abortion can be done not only in the classical way, but also with medication.

But, there are also drugs that can be used to terminate a possible pregnancy almost immediately after sexual intercourse, if it was unprotected. To such drugs emergency contraception Postinor applies. For example, if sex was unprotected, you can take it the next day, running to the pharmacy in the morning. In most cases, it works and pregnancy does not occur.

But, all the same, then, if you still have any suspicions, it is better to double-check, do a test, at least just to calm yourself down and get rid of the obsessive thought.

Features of Postinor

Many women mistakenly believe that Postinor is a kind of birth control pill, one of the varieties. This is not entirely true. Manufacturers state that their product does not protect against unwanted pregnancy, but it causes abortion at the shortest terms, i.e. a few hours after coitus.

It all depends on whether or not. Therefore, in different cases its effects may differ from each other, but the ultimate goal pursued by a woman taking this drug will be achieved - she will not become pregnant.

Postinor contains 0.75 mg of levonorgestrel, which is a synthetic hormone. It is also found in other classical oral contraceptives, but in much smaller quantities.

There are two options this drug:

• Option 1: the drug slows down the release of the egg into the fallopian tube from the ovary, which helps prevent its fertilization. Therefore, pregnancy does not occur.
• Option 2: This option works if fertilization does occur. The fertilized egg must attach securely to the wall of the uterus. It is there that the fetus will develop and grow throughout the 9 months of pregnancy. If you take Postinor, it affects the structure of the inner lining of the uterus, changing it temporarily. Therefore, the fertilized egg cannot securely attach to the wall of the uterus, which also terminates the pregnancy.

In the vast majority of cases, Postinor taken on time really helps to solve the problem of unwanted pregnancy and prevent it. But, if everything were so simple and harmless, everyone would just drink it, without using any other contraceptives.

The drug has many side effects and contraindications, so under no circumstances should you use Postinor too often, as it is harmful to female body, can cause severe hormonal imbalances.

As for the manufacturers themselves, they also do not give 100% guarantees that their product will prevent unwanted pregnancy. The approximate chance that it will work is 85%. Despite this, in the vast majority of cases pregnancy does not occur. This is also due to the fact that not after every sexual intercourse, even unprotected, the egg is fertilized. Therefore, the total percentage is greater than the stated 85%. This is the main reason for the popularity of this drug.

Should I keep Postinor in my medicine cabinet? It is better not to keep it because taking it is not very beneficial. If suddenly, a woman and her partner want to have sex and there are no contraceptives at hand, she will do it with peace of mind, because Postinor is in stock. Many begin to abuse it, which negatively affects their overall health. Therefore, it is better not to keep it, and if you have had unprotected sex, 72 hours is enough to run to the pharmacy and buy it.

Side effects and consequences after taking Postinor

Since there is a large dose of the hormone, this, of course, affects the general hormonal background. In addition, it interferes with blood clotting and can cause bleeding, moreover, repeatedly. This is one of the most common side effects of Postinor. Nausea, dizziness and headache.

This rapid contraceptive should only be taken when extreme cases. In general, it is better to protect yourself, use a condom, or regularly take regular oral contraceptives. But, if you still have sexual intercourse without using contraceptives and the risks of getting pregnant are very high, you should take Postinor so that you don’t have to have an abortion or give birth later if the woman doesn’t want it.

Opinions about this drug around the world are contradictory. Some people, along with women, have a positive attitude towards him, believing that he saves them from possible unwanted pregnancies and abortions. This is better than giving birth to an unwanted child, or killing him by having an abortion at a later date.

Many have a negative attitude towards Postinor because the drug is intended to terminate pregnancy, considering it murder. But there is also an opinion that pregnancy actually occurs if the fertilized egg attaches securely to the wall of the uterus. Since Postinor allows you to avoid this, it turns out that it does not kill an embryo that has not yet had time to consolidate. Therefore it is not an abortion. Opinions may vary.

The risks of ectopic pregnancy in the future increase, which is also fraught with problems and even surgical intervention when detected at a later date.

If you draw conclusions, it is difficult to say whether you should take it or not. It all depends on the situation, each woman decides for herself what is best for her. The main thing is not to overdo it.

Reviews from those who took Postinor

• Veronica: “We lived with my future husband for about a year, and our method of contraception was coitus interruptus. Girls, do not believe that PPA will protect you from pregnancy! This is wrong! In order to avoid pregnancy, the most effective ways are oral contraceptives, the IUD, or at least a condom! One day after sexual intercourse, we were not sure that everything had gone as usual, and I decided to take this “miracle pill” Postinor. I accepted it and accepted it and forgot about it.Delay after Postinor: is it real? It turns out yes. Pregnancy after Postinor is possible. When my period did not come on time, I thought that my cycle from Postinor had gone wrong and I went to the gynecologist. Imagine my surprise when she said that I was 7-8 weeks pregnant! After all, according to my calculations there should have been a maximum of 5! It turns out that my pregnancy came earlier, and I took Postinor while pregnant. And it had no effect on the child, the miscarriage did not occur on his mental and physical health didn't have any effect either.After this, my future husband and I decided to have a child, which I am very happy about now! Do not believe gossip from the Internet that after Postinor you will definitely have down children and do not rush to have an abortion if you find out that you did get pregnant after Postinor. Using my example, you can be convinced that children can be born absolutely healthy (Apgar 8-9) and I am so glad that now I have it! Of course, all this should be confirmed by tests and ultrasound, but there is no need to be afraid in advance!”
• Elena: “I would give a lot not to take this pill one day, because the risk of pregnancy was minimal. But nothing can be changed, I hope my story will help someone not to make the same mistake. After unprotected sexual intercourse, it got into my head that I should take Postinor just in case, I went to the pharmacy, bought it and drank it there. I felt suddenly ill: my head was spinning, it became hard to breathe, my hands and feet were cold, I felt like I was petrified. I couldn’t just walk, it’s good that I wasn’t alone and they took me home, where I immediately went to bed. The next morning I didn’t feel better, it was time to take the second pill, but I was seriously afraid of dying right there, so I decided to tell my parents everything. Oddly enough, they understood me and forced me to immediately call the gynecologist. The doctor forbade me to take the second pill because my symptoms were so obvious side effects. The doctor also said that, even if the pregnancy took place, any abortion would be safer for the body than this Postinor!I wasn’t pregnant then, but “thanks” to that little pill, I haven’t been away from the doctors for a year now: diagnosed with VSD, functional disorder without organic disorders, I feel incredibly bad, but they cannot identify the cause. At 20 years old, I already feel like an old woman! And all the doctors, when they find out about Postinor, say without hesitation that it is to blame.Of course, this is my individual reaction, but after my case I searched a lot for similar ones and found the program “Criminal Abortions,” which I recommend for viewing to everyone who wants to use Postinor. There a girl died of a heart attack after taking this pill. It’s better to be a single mother than to die from your desire to “live for yourself!”
• Julia: “I only took these pills once. This happened when my boyfriend and I broke a condom. What to do and where to run? Google helped me, since I had never heard of such pills before. At the pharmacy, blushing, I asked them to sell it to me, and the angry pharmacist looked at me with a disapproving look and said that there were 2 tablets.The manufacturer warns in the instructions about many side effects, of which I only experienced slight dizziness. As a result of taking them, my cycle was a little off, but it wasn’t that bad.”

This medical product has a powerful effect, therefore its use should be carried out only after consultation with a gynecologist.

Later, the medicine has virtually no effect on the pregnancy that has taken place. Gynecologists strongly do not recommend using the medication on your own. Before use, the patient should consult a doctor and receive individual recommendations.

Medicinal substance has an effect on a woman's ovaries. It blocks the functioning of the reproductive organs. This leads to reverse development of the follicle and cancellation of ovulation. If the release of the egg has already occurred, the medication acts on the corpus luteum, suppressing its work. In addition, the product makes cervical mucus more viscous.

What to do if you don’t get your period after taking the pills

After finishing taking Postinor, menstruation can begin either in a few days or on time, according to menstrual cycle women. Since the drug contains a significant dose of second-phase hormones, this can lead to a disruption in the cycle and a delay in menstruation, but not more than 7 days.

If after taking your period your period does not come on time and is delayed for more than a week, then you need to make sure that there is no pregnancy. Repeated use of the drug is unacceptable. If pregnancy occurs, then Postinor will not have any effect on it, since it is not a means for medical abortion in case of implantation of the fertilized egg. For further advice, you should consult a doctor.
If menstruation is delayed by more than 7 days, pregnancy must be excluded.
