Can The Morning After Pill Delay Your Period

Types Of Emergency Contraception Pills

What causes delayed periods after taking emergency pills? – Dr. Teena S Thomas

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.

    Here is a list of some possible side effects after using a “morning-after” pill like Plan B:

    • Irregular bleeding
    • Fatigue

    What Choices Are Available For Emergency Contraceptive Pills

    There are three types of emergency birth control pills available in the United States:

  • Progestin only: These pills contain only the hormone progestin. They are sold under the names Plan B One-Step, Next Choice One Dose, Take Action, My Way, and more. Its available over-the-counter to anyone of any age.

  • Ulipristal acetate: Another option is a pill containing ulipristal acetate. Its sold under the name ella in the United States and is available by prescription only.

  • Progestin plus estrogen: Combined hormonal pills contain both progestin and estrogen these are the typical daily birth control pills that you can get by prescription. Find out more about which brands can be used as emergency contraception, and how, from the Office of Population Research at Princeton University.

  • No matter which option you choose, it should be taken as soon as possible after unprotected sex. Plan B One-Step indicates it should be taken within 72 hours after sex ella should be taken within 120 hours. But the sooner you take it, the better chance it works.

    Is It Safe To Delay Periods

    Trying to stop, skip or delay anything that is natural is going against nature but not necessarily harmful. But if someone overdoes popping of pills, they can affect their body.

    Every woman has a different system. Many have irregular periods all the time and some only have such a situation when theyre pregnant or breastfeeding. While it is unnatural to stop your period completely, combined contraceptive pills can help delay it. Combined contraceptive pills are the ones that help delay the period and avoid unwanted pregnancy. The combined oral contraceptive pill is usually taken for 21 days followed by a seven-day pill-free time, during which you will experience a bleed. These were designed by doctors in an attempt to replicate a womans natural cycle, which is why there is a seven-day break for a bleed to occur. You can take these pills back to back but it is recommended by the doctors that you must have 2-3 bleeds a year to allow your womb lining to shed.

    Dr Uma Vaidyanathan, Consultant Gynaecologist and Unit Head at Max Hospital, New Delhi, says that a one-time use of period delaying pills is perfectly fine. However, one should not make it a habit of using these pills quite often as these pills suppress the natural hormonal cycle of the body. One should use it until their purpose is served and get back to their routine as early as possible.

    Changes In Your Period

    Taking a morning after pill can cause your period to be lighter or heavier, or arrive earlier or come late. These side effects are due to the high-dose progesterone acting on the lining of the uterus at variable points in time during the menstrual cycle, says Hoskins.How it affects your cycle depends on where exactly you are in your cycle when you take it. And while it may cause changes, these are always temporary, especially when the pill is used correctly, i.e. very rarely/occasionally and not regularly and repeatedly, she says.Your next period should be normal, and come at the expected time, or within a week of the expected time.

    When Will You Get Your Next Period

    You may experience some irregularities with your period after taking emergency contraception, but you should have a normal period within the following month, according to the Princeton University website for emergency contraception.

    When your period arrives may be related to when you took the emergency contraceptive pill. Generally, women started their periods a day earlier when they used emergency contraception more than two days before ovulation, and their periods were two days later than expected when they took the pills more than two days after ovulation, according to a study completed at Princeton. Because taking the emergency contraceptive pill does not guarantee that you wont get pregnant, you should take a pregnancy test if your period is more than a week late.

    You may also notice some spotting after taking the medication and before your next period. You might notice that your first period is lighter or heavier than normal. This should resolve by the following month.

We used a condom and I took the pill just to make sure.

    Official Answer

    The morning after pill is a safe and effective way to prevent pregnancy after unprotected sex. It will be most effective if taken as soon as possible after unprotected sex. Within 24 hours is best, but it can prevent pregnancy if taken up to 120 hours after sex. Side effects are usually short-term and mild. Some women feel sick and it helps to take the pill with food. Anti-nausea tablets are available on prescription if needed. Some women experience a change in bleeding pattern and this is in response to hormone fluctuations. Your next period may come at the normal time, but it may be early or late and it could be heavier than usual. All scenarios are normal.
