Does Plan B Make Your Period Come Early

How Effective Is Levonorgestrel

I missed my period. Is it because I took the i-pill, or am I pregnant?

If you take the pill within 72 hours after you’ve had unprotected sex, levonorgestrel can reduce the risk of pregnancy by up to 87% if taken as directed. If you take Plan B One-Step within 24 hours, it is much more effective.

But you should know that Plan B One-Step is not as effective as regular contraception. So don’t take it as a form of birth control. And, it does not protect you against sexually transmitted diseases. Think of it as a backup — not for routine use. That’s why it’s called Plan B. Get more information on emergency contraception and its effectiveness.

More Faqs On Delayed Periods After Morning After Pill

  • Can the morning after pill mess up your cycle for months?
  • Yes, it can. Although it will not cause significant harm, taking the EC pill more than once in a cycle can mess up your cycle for months. And this is why we advise you to have a regular, reliable form of contraception, so you only need the morning after pill occasionally or rarely.
  • What it means – morning after pill, period late 2 weeks?
  • In this case, I would recommend a urine pregnancy test straight away. If the test is negative, you can wait another seven days and repeat it. At this point, you can also look for signs of early pregnancy like breast soreness, tiredness and so on.
  • Bleeding a week after plan b – is that my period?
  • Most often, bleeding that happens soon after taking the pill is a side effect of the hormones in the pill – not your period. The bleeding also tends to be lighter than a period, e.g. spotting. Even if the bleeding is a little heavier, it will not cause blood clots. It will not last as long as a usual period.
  • What are the side effects of morning after pill on menstrual cycle/effects of morning after pills on periods?
  • The pill has two main bleeding effects: it can i) cause bleeding unrelated to the menstrual cycle and ii) affect the periods.
  • For the periods, the pill can have zero effect. That means the period is unchanged and comes at the expected time. In other cases, it may be delayed or might come earlier.

    How Does The Morning

    The morning-after pill will prevent or delay the release of an egg from the ovary if given prior to ovulation, or it will help prevent the egg from traveling down the fallopian tubes and implanting in the uterus if you have already ovulated. The morning-after pill reduces the chance of getting pregnant it does NOT cause an abortion.

    Heavy Bleeding A Week 5 Or 4 Days After

    Heavy bleeding seven days, 5 or 4 days after taking plan B is considered normal. The bleeding is occasioned by the shedding of your uterine lining, which is exactly what plan B was designed to do. You will find that your next period will pick up in the following month.

    However, it is recommended that you do not engage in unprotected sex until your normal cycle is back. If possible, ensure that you get on a birth control method, as Plan B One-Step should only be used as an emergency method, and not as a regular method of birth control. It is always best to practice safe sex as it also reduces your chances of contracting an STD.

    Other Causes Of Bleeding

    In the weeks after taking Plan B, light spotting between periods or a heavier flow are not typically a cause for concern. However, if these issues do not go away within a month or so, something other than Plan B may be responsible.

    Heavy bleeding and intense pain can signal a serious underlying condition, such as endometriosis. Also, heavy bleeding can indicate an early miscarriage.

    A healthcare provider should assess all heavy bleeding. If a persons periods are irregular and heavy, taking additional hormonal contraceptives can help. If the bleeding results from pregnancy loss, the doctor may recommend surgery to remove remaining tissue.

    What If It Didnt Work

    A few factors play into Plan Bs effectiveness. Doctors recommend taking it within 72 hours after a whoopee whoopsy so you have 3 days to head to the pharmacy and pick it up. If youre already on birth control, you should keep taking that as you normally would.

    Research shows that, while its generally effective, Plan B doesnt have a 100 percent success rate. About 7 out of 8 women who wouldve become preggo wont conceive if they take Plan B within 3 days after sex. That means 1 out of 8 will get pregnant.

    Plan B may not work if you vomit within 2 hours of taking it. Additionally, body size may come into play. It may be less effective in women who have a BMI over 25 or who weigh more than 165 pounds.

    But thats doesnt mean for sure that it wont work.

    Is It Normal To Bleed After Plan B

    It is normal to bleed after taking plan B, and as such, there is no reason for you to worry in case you experience bleeding after plan B. Even though this side effect is not very common, these pills contain hormones that could influence the hormones that are already present in your body, and may, therefore, cause some women to start bleeding at unexpected times.

    According to, approximately twenty-five percent of all women who take plan B emergency contraceptive pills are likely to notice some changes in their menstrual cycle. As mentioned earlier, you need to consult your physician if this bleeding goes on for more than a few days, as it could mean that there is a serious underlying issue.

    Is Bleeding After Plan B Normal

    “It is common for there to be unexpected or atypical bleeding after taking Plan B,” says Felice Gersh, MD, the medical director of the Integrative Medical Group of Irvine.

    Around 15% of people experience bleeding right after taking Plan B, before their period starts. This means that you may have spots, but that your period doesn’t start right away.

    In other cases, Plan B can trigger your period to come early, so bleeding may be a sign that it’s working, Gersh says.

    Bleeding can start and stop any time in the first three weeks after taking Plan B. The length of your bleeding can vary, but it generally won’t last longer than a few days.

    Plan B works by delivering a chemical called levonorgestrel, which mimics the hormones that control your menstrual cycle. Levonorgestrel can stop your ovaries from releasing an egg or stop a fertilized egg from implanting in your uterus.

    Taking Plan B can cause bleeding because levonorgestrel changes the stability of the uterine lining that you shed during your period, which can lead to unexpected bleeding, Gersh says.
