Key Learnings

⦁ Menstrual cycle abnormalities are one of the most prevalent adverse effects of hormonal birth control tablets like Postinor-2.
⦁ Levonorgestrel is the active element of Postinor-2, an emergency contraceptive that shouldn’t be used as a daily birth control pill.
⦁ Menstruation-related side effects of Postinor-2 include altered menstrual cycle patterns, heavier menstrual flow, and altered menstrual cycle duration.


Again, you engaged in unprotected sex—not it’s like you did it on purpose. The simplest course of action would have been to wear a condom since you were no longer taking the usual pill, but things grew so heated that you and your spouse found themselves in bed together in the blink of an eye.

Everything is now over. You realise that you still have two more semesters of school to complete and cannot afford to have a family immediately as you are both coming down from high.

First, according to the World Health Organization (WHO), adolescents can safely use emergency contraception. Second, the group asserts that emergency contraceptives have no impact on future fertility. Third, postinor-2 does not harm the womb.

The menstrual cycle, perhaps? You might be concerned about how medications like Postinor-2 will impact your menstrual cycle. Birth control tablets may alter menstruation and the menstrual cycle since they include hormones. As a result, they can influence a variety of features of your period, although the effects frequently fade or disappear with time.

During the few first months of using the pill, those on regular birth control pills, such as progestin-only or combination tablets, may experience side effects, including irregular bleeding or spotting. The same is true with over-the-counter birth control tablets like Postinor 2, which might result in irregular periods for a month after use.

This article will go over the operation of postinor-2 and any negative effects it may have on menstruation. We will also discuss additional postinor adverse effects of postinor-2 on the womb
that could occur, and when a physician should address menstrual cycle problems.

Functions of Postinor-2

Levonorgestrel is a component of the emergency contraceptive pill (ECP) known as Postinor-2. In addition, a group of drugs known as progestins includes Levonorgestrel. Progestins hinder fertilisation by blocking the release of an egg from the ovary.

Experts and doctors explained Postinor-2’s mechanism of action to SemicHealth, saying that the drug also thickens cervical mucus due to its physiological effects.

Postinor-2, according to docs, may alter the endometrial lining of the uterus, making it less amenable to implantation and conception.
Postinor-2 may not lower the pregnancy rate if taken after ovulation, according to data. Additionally, if given after conception, it cannot stop implantation.

Postinor 2’s effects on the menstrual period

Even though Postinor-2 is considered safe to take, regular users may experience missed periods because it affects the menstrual cycle. Even when taken multiple times during a cycle, it frequently has minor negative effects.

Effects of postinor-2 on the womb include

⦁ alterations in the menstrual cycle’s duration
⦁ A period that is later or earlier than anticipated
⦁ Variations in the flow’s volume (such as heavier or lighter flow)
⦁ Spottings

In the absence of any preexisting conditions, periods are likely to return to regular patterns, experts noted. “These changes are frequently temporary.”

How frequently should Postinor-2 be taken?

An emergency contraceptive, Postinor 2, should be used in forced sex and contraceptive accidents (such as damaged condoms and forgotten pills).

Postinor-2 is not intended to be used as a regular birth control pill. However, continued use may not result in major health hazards. Older studies show that Postinor has a failure rate of less than one and may only have a limited number of negative effects when taken no more than four times per month.

It is not recommended to use Postinor-2 frequently. Instead, patients should use different approaches to engage in regular unprotected intercourse.

Additional negative effects of Postinor 2

There are some potential negative effects of postinor-2 on the womb. However, they are frequently mild and transient.

Intermenstrual bleeding and irregular menstruation are the negative effects of contraceptive emergency pills like Postinor 2 that are most frequently reported. Additionally, some patients mention unpleasant side effects such as nausea and stomach pain.

Postinor 2 adverse effects are listed on the consumer medicine information (CMI) leaflet as follows:

⦁ Tiredness
⦁ nausea and diarrhoea
⦁ Dizziness
⦁ abdominal pain
⦁ Headache
⦁ Diarrhoea
⦁ Breast sensitivity
⦁ Skin repercussions
⦁ Enhanced vulvar bleeding

When to consult a physician about menstrual cycle problems

Postinor-2 may impact your menstrual cycle, but this is not always the case. Some people have problems with their menstrual cycles due to hormone-related medical illnesses. Polycystic ovarian syndrome (PCOS), pelvic inflammatory illnesses, uterine fibroids, and endometriosis are medical conditions that can interfere with your menstruation.

Unusual alterations in the menstrual cycle can also be caused by pregnancy, stress, and lifestyle choices. Always consult your gynaecologist if you detect any changes, particularly if they frequently occur with your menstrual cycle or period flow.

Your gynaecologist will suggest a few tests to rule out any major medical issues. Then, they will talk to you more if you should begin a treatment plan.

Can postinor two wash sperm away?

No, Postinor 2 mainly functions by postponing ovulation. According to some studies, it might thicken the mucus in your vagina or alter the lining of your womb, preventing sperm from moving very far within the womb. Or, even if the sperm and egg are fertilised, the embryo may not be able to establish itself in the womb. Overall, postinor two primarily functions by delaying ovulation because other research does not demonstrate that it does this successfully.

 Remember that Levonorgestrel causes a five-day delay in ovulation. You run a second danger of becoming pregnant if you have sex at this period without using condoms. Therefore, after taking the emergency pill, switch back to your regular method of contraception or, in this case, use another emergency method.

When does postinor 2 start working?

When used as soon as possible after unprotected sex and during the portion of your cycle before ovulation, Postinor 2 is most effective.

Does postinor two benefit nursing mothers?

Postinor 2 is safe for moms who are nursing. However, it is advised that women take the tablet right after breastfeeding because a small amount goes into the breast milk. After that, you can feed your infant extracted milk until you’ve gotten to the second table.

Can postinor two postpone periods?

Yes, Levonorgestrel is the name of the hormone found in Postinor 2. Luteinizing hormone, sometimes known as LH, or ovulation, occurs when it reaches a specific amount in the body (LH peak). At this point, your body instructs the ovary to release a fully developed egg. Depending on how the tablet affects the event’s timing, the next period may arrive earlier than usual or later than usual. Menstruation might occur at the same time each month for certain women.

Will postinor two cause a delay?

Yes, for some women, postinor might postpone their menstruation. Although it happens less frequently, delays of even a few days or weeks can occur. You should check for pregnancy if your period is seven days later than usual. We could consider other potential explanations if it takes more than a few weeks and a blood pregnancy test returns negative.
