When pregnancy is not included in the plans, but had unprotected intercourse (PPA), women resort to emergency contraception drugs - such as postinor. However, the guaranteed "protection" against unwanted fertilization can not provide any one of the means of contraception. What if Postinor month after receiving absent for a long time? How many can take the delay caused by the influence of the active ingredients in the body, and how soon will come the critical days? Let's look at this together, drawing on the views of practitioners and gynecologists.
Release form and function
Based on the pharmaceutical characteristics postinor - means for emergency contraception oral designed specifically for preventing unwanted pregnancies in the first 72 hours after PPA.
Means produced in the form of two white tablets coated with a protective sheath. In most cases, a means to acquire emergency contraception without a prescription.
What has a contraceptive effect on the body, providing an instant "sterility"? To answer this question let's look at the chemical composition of the drug.
levonorgestrel
The main active components of emergency contraceptive postinor - artificial hormone levonorgestrel. This material is a synthetic analogue of steroid hormones female wearing generalizing name "progestogens".
Produced in large doses, these compounds are capable of blocking the process of ovulation, and thus prevent pregnancy.
This artificially synthesized hormone is widely used in all kinds of oral contraception. Dosage varies solely to be included in the chemical formula of a medicament.
Such popularity among 19-norsteroidov levonorgestrel was due to 100% bioavailability. Preparations on the basis of a synthetic hormone, falling into the gastrointestinal tract, are absorbed completely, and thus, active ingredients penetrate into the bloodstream in full, ensuring maximum exposure kontratseptiruyuschee within 1.5-2 hours after taking capsules.
It is thanks to this property, postinor pills are considered the best in the segment of emergency contraception.
In addition to 750 mg of levonorgestrel, based on the pharmacological "history" of tablets, they contain silica, magnesium stearate, potato starch, corn starch, talc and monohydrate lactose.
hormone action
The active substance of this tool - levonorgestrel, not only immediately blocks ovulation. Synthetic hormone causes systemic changes in the endometrium of the reproductive organs, causing the impossibility of attaching the already fertilized egg to the uterine wall.
When receiving the tablets after several hours of unprotected intercourse, and changes the nature of mucus in the cervix. The liquid becomes more dense and viscous, preventing movement of sperm.
Such an impact not only prevents the onset of a possible pregnancy, but also deals a powerful blow to the work of all the organs of the reproductive system.
Based on reviews from the majority of women have tried pills for yourself, there is a delay menstruation after drinking Postinor.
How to apply postinor
Based on the instructions, take a tablet in the amount of two pieces at once. Between meals capsules should be a time interval constituting 12 hours.
This drug emergency contraception ensures positive after the first pill in 95% of cases. It is worth noting that the maximum postcoital effect can be achieved in the first days after the NPA. Clinical trials have shown that the use of Postinor 48 hours after having sex without protection reduces the efficiency to 85%. Obstacle to pregnancy 72 hours after sexual intercourse without using contraception reduces the "positive interest" up to 58%.
The earlier a woman took the drug, the higher the percentage of absence of pregnancy.
Doctors do not recommend very often resort to using emergency contraceptive pills. Such an impact can cause serious injury to the body of women and lead to irreversible consequences!
As postinor affects the monthly

It is worth noting that the quality and quantity of rejects at the time of liquid may not reflect the usual month. Depending on the individual representatives of the weaker sex, blood clots can be epithelial and plentiful and anointing, barely noticeable character.
Women celebrate the presence of the dense dark clots in the consistency of rejects after receiving Postinor mucus. Such changes are physiological reactions to levonorgestrel and showed no pregnancy.
No monthly after Postinor
Distributed cases when after receiving Postinor cycle is not recovered for a long time delay and female monitors monthly. The first thing a woman thinks - the possibility of the lack of action of the drug.
Wholly prevent conception, the drug is not guaranteed, and 5% of women still pregnant, so in the absence of monthly 7 days or more, it is necessary to conduct a home test.
