Plan B Spotting Vs Implantation Bleeding

You may experience spotting after taking Plan B. It is a common side effect of the medication.

However, some may believe that spotting is actually implantation bleeding, which is a small amount of light bleeding that typically occurs 10 to 14 days after conception, suggesting a possible pregnancy.

One difference between spotting after Plan B medication vs. implantation bleeding is:

  • Implantation bleeding can usually be pinkish. It is also rare for females to experience implantation bleeding
  • On the contrary, spotting after Plan B is common, and it is usually reddish or brown

The other test that will help confirm the difference is undergoing a pregnancy test, putting your mind at ease.

Changes In The Menstrual Cycle

In a clinical trial, 31% of participants experienced some change in their menstrual cycle after taking Plan B, but the potential menstrual changes are varied. Plan B may cause some women to experience heavier or lighter menstrual bleeding compared to their regular periods.

After taking Plan B, some women get their period sooner than expected, while others get it later. However, clinical trial data suggest most women will get their period within two days to one week of the anticipated time. Women who take Plan B and experience a delay in their period greater than one week are recommended to take a pregnancy test.

During your menstrual cycle, the time at which Plan B is taken can affect how your menstruation changes.

  • Some studies suggest that taking Plan B early on in your menstrual cycle can increase the likelihood of spotting before menstruation begins and can sometimes cause the next period to be shorter than usual.
  • When Plan B is taken later in your menstrual cycle, it may not affect period length, or it may be more likely to result in prolonged menstrualbleeding.

What The Pill Does

The emergency pills work by delaying ovulation, that is, the release of an egg from the ovary.

  • In a woman with a regular 28-day cycle, the release of an egg usually happens about 14 days following the first day of the last menstrual period.
  • A regular cycle means you usually will have a montly bleeding about the same time each month with one or two days earlier or later on some occasion.
  • The day after ovulation, ovulation day and the four days just before ovulation are known as your fertile window.
  • Your fertile window is the time of the month during which you are most likely to fall pregnant. But the timing of the fertile window can change from one month to the next, even in a woman who has a regular cycle.
  • Some studies suggest that more than 7 out of ten women may be in their FW before day ten or after day seventeen in their cycle.
  • Using a good ovulation app can help you keep track of your periods. You can also estimate your fertile window if you have a regular cycle.
  • The pill changes your hormones to prevent the release of the egg, usually till sperm from sexual activity have died off.

    Since we know that sperm can remain alive in the woman for 3-5 days, the hEC pill delays ovulation for 5 days after which you then ovulate.

    If you do have sex again after the postponed ovulation happens, you could get pregnant despite the pill. Hence you must resume your regular contraception method straight away or use another emergency pill after sex.

    The Side Effects Of Plan B

    How Does Plan B Affect Your Period?

    The way emergency contraceptives work is that they contain a large dose of levonorgestrel. Levonorgestrel is a synthetic hormone that mimics the sex hormone progesterone, which prevents ovulation and, hence, pregnancy.

    Plan B and other emergency contraceptives contain 1.5 milligrams of levonorgestrel. That’s three times more than what you get in a regular birth control pill. As a result, this large, concentrated dose can cause side effects like:

    • Fatigue
    • You might also notice changes to your menstrual cycle, like irregular bleeding.

    Less common side effects include:

    • Vomiting
    • Headaches
    • Breast tenderness

    While plan B side effects can be uncomfortable, they shouldn’t feel excessively extreme or severe. Pelvic pain and a disruption in your cycle should be the most severe side effects of taking plan B.

    If you experience side effects that go beyond these symptoms, or if they worsen after more than a few days, consider consulting a doctor. Moreover, if you notice irregularities in your period persisting for more than one cycle, take a pregnancy test.

    How Does Plan B Work

    Plan B® works as an emergency contraceptive by preventing ovulation , or if ovulation has occurred, it may prevent sperm from reaching the egg. In addition, Plan B® may prevent the implantation of a fertilized egg. If implantation has already occurred, Plan B® is not effective. It cannot be used to end a pregnancy after implantation has occurred. Plan B® is intended for emergency use and should not be used as a replacement for birth control.

    If you took Plan B® and now your period is late, you may want to come in for a pregnancy test. A support worker will provide a free pregnancy test and discuss your options with you.

    Research Findings Vs Fda Labeling

    Monique Rainford, MD, is board-certified in obstetrics-gynecology, and currently serves as an Assistant Clinical Professor at Yale Medicine. She is the former chief of obstetrics-gynecology at Yale Health.

    Plan B One-Step is an emergency contraceptive. Emergency contraceptives are used to prevent pregnancy after birth control failure or unprotected sex. Generic forms of Plan B include My Way, Take Action, and Next Choice One Dose.

    Emergency contraception is safe and effective. Still, Plan B is controversial. Much of the debate is based on a misunderstanding about how Plan B works.

    Some people believe Plan B prevents a fertilized egg from implanting in the lining of the uterus. This belief is based on the product’s FDA labeling. Research, however, has not confirmed the information on the FDA label.

    This article will discuss the controversy around the FDA labeling for Plan B. It will also look at what research says about how Plan B actually works.

    Emergency Contraception Pill Forms

    EC pills come mainly in 3 different forms.

  • The most common method is Levonorgestrel , an artificial progesterone similar to the Progesterone found in your body. It is what you find in the most familiar methods like Plan B, Take Action, Post pill, Postinor, and so on.
  • With Levonorgesterel, you have up to 72 hours of having unprotected sex in which to use the tablet. It is up to 95% in preventing pregnancy when taken within the first 24 hours. This reduces to about 89% by the 3rd day after sex. Thereafter, it is not reliable.
  • The second form of emergency contraception pill known as Ella contains the antiprogesterone, Ulipristal acetate. It is the most effective emergency pill method you can take .
  • Less commonly, some types of the combined pill can be used as emergency contraception. However, this is less effective than the Ella or LNG and not frequently recommended.

    Period Update: Missed Period, Pregnancy Test and Plan B | How late was my period?

    Plan B is 95 percent effective if taken within a day after sex and 88 percent if taken between 3 days after. But theres always a slim chance it wont work.

    If you take Plan B and your period is over a week late, theres a slight chance that you might be pregnant. Take a pregnancy test to play it safe.

    If its been 2 weeks, your pregnancy odds are even greater and you should likewise take a test. If your pregnancy test is positive, visit a doctor or midwife to confirm your result and walk you through your options.

    If youre not sure what stage of your cycle youre at or you have irregular periods, Planned Parenthood recommends waiting 3 weeks after taking Plan B before you take a pregnancy test.

    Pregnancy tests measure the hormone human chorionic gonadotropin , which the body starts to produce a few days after conception. So if you take a test too early, it could show a false-negative result.

    If your period is still MIA 2 months after taking Plan B, you could be pregnant. Its unlikely its the EC still messing with your cycle.

    Take a pregnancy test and visit a doctor or midwife ASAP to know for sure.

If you notice unusual delay in your period, you may want to take a pregnancy test to confirm if you have already conceived.

    • In the first study, women experienced their period sooner than expected when they took 1.5mg levonorgestrel in the first three weeks of their monthly cycle. However, there was no change in the menstrual cycle for women who took Plan B in the fourth week of their cycle.
    • The second study showed that the period arrived at usual time for women who took 1.5mg levonorgestrel within two days before or after ovulation. Some women had their period a day earlier when they took contraception more than two days before ovulation.The duration of menstrual period increased when emergency contraception pills were taken three days before ovulation. About 15% of women experienced inter-menstrual bleeding when they took ECPs during the pre-ovulatory phase.

    Can The Morning

    Yes, although generally speaking, most women who use the morning-after pill have minimal or no significant changes to their menstrual cycle. Nonetheless, changes can last for 5 to 7 days. It is important to highlight the the repetitive or frequent use of the morning-after pill can worsen any menstrual disturbances, making it difficult to identify your fertile days and menstrual phase.

    It is also important to note that bleeding usually does not occur immediately after taking the morning-after pill.

    When To Use It

    Plan B One-Step should be taken as soon as possible within 72 hours of condomless sex or contraceptive failure to reduce the risk of an unplanned pregnancy. The sooner Plan B One-Step is taken, the more effective it’ll be. Plan B One-Step can also be used any time during your menstrual cycle. However, if you vomit within two hours of taking the pill, you should immediately contact your healthcare provider to discuss taking another pill.

    Note: In general, emergency contraception can be used up to five days after condomless sex. So it may still be useful to take Plan B One-Step for up to 120 hours after condomless sex.
