Can Plan B Make Your Period Late

Why Does Plan B Affect Your Period This Way

How late can your period be after taking Plan B?

Plan B uses a synthetic hormone called levonorgestrel to prevent pregnancy by stopping an egg from being released.

Levonorgestrel is found in birth control pills, but Plan B contains a higher dose that can alter your bodys natural hormone levels.

The extra hormones can, in turn, affect the menstrual cycle, leading to an earlier or delayed period as well as heavier or lighter bleeding.

How Can Plan B Affect Your Period

There are two types of emergency contraceptive pills , but you can expect these kinds of menstrual changes to happen after taking either of them:

  • An early or late period after taking the pill
  • Changes to your next period

Researchers at Princeton University looked at past studies and said that menstrual cycles could be shortened after taking Plan B, meaning that the time between now and when you get your next period could be shorter. When we talk menstrual cycles, we’re tracking the first day you get your period as day 1, up until the first day of your next period. Everyone’s different, but usually, you’d get your period every 28 days or so.

They also found even if Plan B didn’t shorten the time until your next cycle, it could cause your next period the following month to be longer.

Why Can Plan B Delay Your Period

Taking Plan B creates a hormonal imbalance in your body. While that sounds like a bad thing, it really isnt. Basically, Plan B contains high levels of progesterone. Progesterone is a hormone that naturally occurs in a womans body when she is pregnant. Progesterone slows down the ovulation process or stops it entirely which is why it occurs in such high levels while a woman is pregnant. You certainly dont want to be ovulating while youre already carrying a baby. When you take Plan B, you are getting a high dosage of that hormone which in effect tricks your body into thinking its already pregnant which stops the ovulation process. When the hormone level begins to decrease rapidly , your body then thinks youre no longer pregnant and begins the ovulation process all over again. This is also why some women experience bleeding or spotting after they take Plan B. Your body passes the blood rich uterine lining and bleeding may occur at this point. This is where the confusion may come in.

Is It Normal To Have Spotting After Plan B

Bleeding can occur within seven days after you have taken this emergency contraception. However, the bleeding should come to an end by the time your next period is starting.

Types Of Emergency Contraception Pills

There are 2 types of emergency contraceptive pills commonly sold in the U.S.:

  • Plan B One-Step – to be taken as soon as possible and within 72 hours of unprotected sex
  • ella – to be taken as quickly as possible after unprotected sex and within 5 days
  • Editor’s note: Technically, a doctor could have you take higher doses of regular combination birth control pills as emergency contraception, something called the Yuzpe regimen. But that’s not as effective as the other 2 types listed above, and it brings with it more side effects. Additionally, the copper IUD could be inserted within 5 days as a form of emergency contraception.

    Scientists have found that both Plan B One-Step that you can get over-the-counter, or the prescription for ella, are safe to use to prevent pregnancy. Any side effects that you have after taking either of the emergency contraceptive pills should be mild and short-term.

    After you take emergency contraceptive pills, the most common side effect is – you guessed it – changes to your menstrual periods.

    What Is In The Morning Pill And What Does It Do

    The morning after pill, otherwise known as plan B, is composed of a high hormonal load of levonorgestrel. Levonorgestrel is a hormone similar to progesterone and is responsible for either preventing or delaying ovulation and/or interfering with egg fertilization: depending on when it is taken. This hormone thickens the cervical mucus so that sperm cannot pass through, in turn hindering the implantation process of the ovum .

    Some morning after pills can also be made up of meloxicam, an anti-inflammatory with contraceptive effects that has been said to have fewer side effects than levonorgestrel.

    Depending on when the pill is taken and which specific type you have chosen, its effectiveness can range between 89% and 95%. It is recommended to take the pill as early as possible within the 72-hour radius.

    What If Its Been Longer Than Expected And Still No Period

    Can a plan B make my second period late?

    Its normal for Plan B to affect the timing of your period. But if its a week later than usual or still hasnt arrived within 3 weeks of taking Plan B, theres a possibility that youre pregnant.

    EC pills containing levonorgestrel can reduce the chance of pregnancy by 95 percent if taken within 24 hours of sex. This lowers to 88 percent if the pill is taken between 24 and 72 hours after sex.

    If youre unsure whether Plan B has worked, take a pregnancy test.

    Take one straight away if you keep track of your cycle and know that your period is at least a week late.

    But if youre not sure where you are in your menstrual cycle, wait 3 weeks after taking Plan B before using a pregnancy test.

    Pregnancy tests detect a specific type of hormone, human chorionic gonadotropin , which is only produced a few days after conception. So taking one too early can produce a false result.

    If your test comes back negative, wait a couple more weeks to see if your period arrives.

    If it doesnt, take another pregnancy test and visit a doctor for advice on delayed periods if the result comes back negative once again.

    If the result is positive, book a doctors appointment. Theyll be able to confirm your pregnancy and talk you through all the available options, including both medical and surgical abortions.

    How Do You Know If Plan B Worked

    Doctors say that you don’t need any tests or procedures after using emergency contraception. However, if you haven’t gotten your period within a week of when it should come or expect it to come, you should have a pregnancy test. Don’t hesitate to talk to your doctor for some good, solid medical advice.

    When you take it as directed, your emergency contraception pill should be safe and effective. The California State Board of Pharmacy says that emergency contraception could reduce your risk of getting pregnant by up to 89%. Note that this number is only an estimate, and it rides upon the fact that you take it on time, as soon as possible after having unprotected sex.

    Period Symptoms Associated With Plan B-Common Gyn Problems

    Some spotting after using Plan B is harmless. It shouldnt be taken as a sure sign that youre not pregnant, though.

    Implantation spotting can happen when a fertilized egg attaches to the lining of the uterus. This is perfectly normal in early pregnancy, usually occurring about 10 to 14 days after conception.

    Youll only know that youre not pregnant when you get your period or have a negative pregnancy test.

    In addition to spotting and menstrual changes, other potential side effects from Plan B may include:

    • nausea
    • breast tenderness
    • vomiting

    If they happen at all, these side effects should only last a few days and you probably wont have all of them.

    Emergency contraceptive pills are not associated with serious or long-term side effects. Plan B wont affect your ability to get pregnant or carry a pregnancy in the future.

    Remember, your period may be late even if youre not pregnant.

    You dont have to do anything for spotting, getting your period early, or a heavier-than-normal period. When you take Plan B, keep some menstrual products on hand just in case.

    Your cycle should return to normal the following month.
