Can Plan B make you infertile?

Plan B is a brand of levonorgestrel “morning-after” pill that can be taken anywhere up to five days after unprotected sex. This morning-after pill can reduce a woman’s chance of pregnancy by 75% to 89%. It’s most effective when it’s taken immediately after unprotected sex occurs and is generally recommended to be taken within 3 days after unprotected sex. Waiting extended periods of time after sex to take the morning-after pill reduces its efficacy. It’s important to note that Plan B might not work for women who weigh over 165 pounds. Plan B and other levonorgestrel pills are considered emergency contraceptives that prevent pregnancy by delaying ovulation. 

Some people believe that taking Plan B can lead to infertility or impair a woman’s fertility. Is this actually true? You can find out if Plan B affects fertility in women by reading the information below.

Is it true that taking Plan B can eventually lead to infertility?

The idea that Plan B will affect your fertility or somehow make you less fertile is a myth. Taking Plan B after unprotected sex will not make you less fertile and will not affect any future pregnancy attempts. Morning-after pills contain the same synthetic hormone that’s in birth control, just in a higher dose. It’s designed to slow or prevent ovulation before it happens and does not work after someone has ovulated. Many people believe that Plan B works by affecting fertilization or implantation, which research suggests isn’t true. Simply put, Plan B doesn’t affect your fertility. It just temporarily slows or stops ovulation so that your body can’t release an egg that could become fertilized.

Some of the most common symptoms women experience following an emergency contraceptive pill include the following:

  • Nausea.
  • Tender breasts.
  • Cramps.
  • Headaches.

These symptoms are relatively typical to experience and don’t indicate any long-term effects on fertility.

It is worth noting, however, that some women who take the Plan B morning-after pill may experience abnormal period symptoms for their first period after the pill. They may notice their periods arrive earlier or later than expected. They may also experience a heavier or lighter flow than normal. This isn’t the case for all women, though. You can typically expect your period to return to your normal after the first one occurs. 

Frequent use of morning-after pills is more likely to interrupt your regular menstrual cycles, which is why it should only be used as an emergency contraceptive. If you’d prefer to be sexually active without becoming pregnant, it’s generally recommended that you use forms of birth control like an IUD, patch, daily birth control pill, ring, condoms, or the shot.
