Can Taking The Morning After Pill Stop Your Period – To understand how the morning-after pill affects your menstrual cycle, let’s quickly look at how both the morning-after pill and the menstrual cycle work. This is just an overview, but you can find more details in our guide to emergency contraception and our blog on how the menstrual cycle works.

In order to learn how the morning-after pill affects your menstrual cycle, we only need to focus on the follicular phase. So, your period has started, meaning the follicular phase has begun. Estrogen and progesterone levels are low, so follicle-stimulating hormone (FSH) does its thing. Rising FSH levels cause the most advanced follicle to mature, grow enough to produce large amounts of estrogen, which triggers luteinizing hormone (LH). LH’s job is to let the follicle know it’s time to release the egg, moving it into the ovulatory phase.

The morning-after pill, when used correctly, interrupts this phase in a particular way. Which brings us to…

Plan B: How Many Times Can You Take It?

The main function of the morning-after pill is to delay ovulation, so that fertilization between a sperm and egg cannot occur. Levonorgestrel-based morning-after pills such as Levonorgestrel, Levonelle, Ezinelle, and Plan B work slightly differently than ellaOne, but ultimately both work to delay ovulation.

Sperm can remain alive in the female genital tract for about 5 days after sex. Therefore, if you ovulate within these 5 days, or just before, you could be at risk of pregnancy as fertilization can occur.

Therefore, to use the morning-after pill correctly, you need to be at the point in your menstrual cycle where you have not yet ovulated. If you take it after ovulation, it is very likely that it will not work. This does not mean that you should not take it or that you will get pregnant, but you may need to look for an alternative emergency contraception to the copper coil (IUD).

Because the morning-after pill delays the ovulatory phase of the menstrual cycle, this can have an effect on when and how your next period comes…

How Do I Know If The Morning After Pill Has Worked?

A common side effect of using the morning-after pill includes a temporary impact on the menstrual cycle. It can be longer, shorter, heavier, lighter, earlier or late…you name it. All of these changes should only last for one cycle before your period returns to what is normal for you.

When they studied bleeding patterns after using the morning-after levonorgestrel pill, researchers found that of 232 participants, 14% experienced irregular bleeding, changes in menstrual cycle length, period length, and menstrual appearance compared to the usual characteristics of your period¹. Another study found that irregular bleeding occurred in only 5% of women in their first cycle after taking the morning-after pill⁴.

Irregular bleeding that is not normal for you after a single dose of the synthetic hormone the day after the pill is likely due to a breakdown in the lining of the uterus, which can lead to bleeding and spotting². This bleeding should not be excessive or prolonged, so if you bleed heavily after using Levonorgestrel, Levonelle, Ezinelle, Plan B, or ellaOne morning-after pills, talk to a healthcare professional to make sure there is no other underlying cause.

As with most contraceptives, everyone is different. Some people will not experience any changes in their menstrual cycle after using the morning after pill, some will find that theirs is quite different from their usual length or intensity.

Where To Get The Morning After Pill

One study³ of 544 participants looked at vaginal bleeding after taking a single dose of the morning-after levonorgestrel pill and 69% found their period to be early, while 21% found their period to be late. delay more than a week. Another smaller study⁴ found that taking levonorgestrel during the first 3 weeks of the menstrual cycle caused periods to come earlier, shortening that menstrual cycle. In contrast, the duration of the first period after taking the pill increased as the pill was taken later in the cycle and was longer in participants who used the morning-after pill than in those who did not they did⁴.

Because the morning after pill delays ovulation, this may mean that your next period may come later than usual. So, if your next period hasn’t come when it’s supposed to, don’t panic. Always take a pregnancy test 3 weeks after using the morning-after pill, even if you have your period on time, to make sure it has worked.

You don’t have to worry about the morning after pill messing with your hormones. There are no long-term side effects on your body or fertility from using the morning after pill. It is safe to use and any changes in menstrual cycle or physical side effects are temporary.

Plan B & The Abortion Pill: How Are They Different?

The emergency pill should not be used as a regular contraceptive method, as its high hormone content can cause menstrual cycle disturbances and other unwanted side effects.

Below is an index with the 9 points we will expand on in this article.

The active ingredient in most morning-after pills is levonorgestrel, a synthetic steroid that mimics the effects of the hormone progesterone.

There are also methods that combine the progestin levonorgestrel and estrogen. On the other hand, we find a new type of emergency contraception whose main compound is ulipristal acetate.

How Effective Is The Morning After Pill And Emergency Contraception?

The emergency pill should be considered as an exceptional method, only in unforeseen situations, such as the condom breaking. For regular sex, other methods are more effective

It is very important to know that the morning-after pill, although it offers a high degree of effectiveness if taken in the hours after intercourse, is not 100% reliable. Despite taking it, there are many cases of unplanned pregnancy.

It’s important to note that hormonal contraceptives generally do not protect against STDs.

The emergency pill has three possible mechanisms of action depending on the time of your menstrual cycle.

Psa: That Is Not A Plan B Pill Inside Your Pregnancy Test

Also, how quickly you take the pill after intercourse also influences how well it works, as it will depend on whether or not fertilization has occurred.

The cervical mucus is disturbed and thickened to prevent the sperm from advancing towards the egg. The motility of the fallopian tubes is also altered.

If there has been fertilization, that is to say, the sperm is attached to the egg, the pill acts on the endometrium of the uterus to prevent implantation of the embryo.

The emergency pill prevents pregnancy if taken within 72 hours of unprotected intercourse. However, this effectiveness decreases as the hours pass since intercourse.

How Many Times Can You Take Plan B?

During the first 24 hours, the effectiveness rate is 95%. However, in the next 24 to 48 hours, this effectiveness has already dropped to 85%.

The effectiveness of the emergency pill is highest when taken within 12 hours of sex and decreases over time.

When the emergency pill is taken on the third day of the sexual act, that is to say, between 48 and 72 hours, it will only be effective in 58% of cases. Finally, postcoital hormonal contraceptives are not as effective at preventing pregnancy as methods used before or during sex, such as condoms.

If you have taken the emergency pill and you are already pregnant, the pill will have no effect on your pregnancy and an abortion will not occur.

Emergency Contraception Pills Are Safe, But Not Always Available

In addition, it is important to clarify that taking the emergency pill, once or several times, does not cause infertility. The hormone content of these pills is the same as all other birth control pills, but with higher doses.

There are several types of morning after pills depending on the active ingredient they contain. The best known are the following:

Is a single pill that carries a dose of 1.5 mg of levonorgestrel. There is also the format in two doses of 750 mg taken in 12 hours. It usually works up to 72 hours after intercourse.

Consists of taking two pills with a dose of 50 µg of ethinylestradiol and 250 µg of levonorgestrel. The first pill should be taken within 72 hours of intercourse and the second 12 hours after the first dose. This method is rarely used today, as it is considered to have low effectiveness compared to the previous method.

Doxypep Is A Morning After Pill To Prevent Sexually Transmitted Infections

Is a non-hormonal contraceptive, as it is a selective progesterone receptor modulator that helps prevent unwanted pregnancies. It was authorized in Europe in 2009 and is more effective than levonorgestrel.

In all cases, the effectiveness is greater as it is taken early in a risky sexual relationship. In other words, the longer it’s been since unprotected sex, the less effective the emergency pill will be.
