Does the Morning After Pill Cause Infertility?

Taking the morning after pill will not impact your fertility in any way. It doesn’t matter how many times you take it, or whether you need to use it several times during a short period.

Emergency contraceptives contain higher doses of the same hormones in birth control pills. However, the dose isn’t so high that it has long-term effects on the body. Morning after pills prevent the ovaries from releasing eggs and sperm from reaching them in the short term. You could become pregnant weeks or even days after taking the morning after pill if you have sex without contraceptives.

If you are struggling to conceive, consult a health care professional for advice. Since you know the morning after pill is not to blame, your health care professional can conduct testing to see what might be the problem and suggest strategies to help you conceive.

Side Effects of the Morning After Pill

While infertility isn’t a side effect of the morning after pill, there are several common side effects you should know about. You may notice the following side effects after taking Plan B or Ella:

  • Irregular bleeding (spotting) a week before or after your period.
  • Nausea, sometimes causing vomiting.
  • Headaches.
  • Dizziness.
  • Breast tenderness.
  • Stomach cramps.
