How Does the Morning After Pill Work?

Depending on what brand you use, a set number of pills need to be taken within the first 72 hours, followed by more pills 12 hours later. According to where you are in your menstrual cycle, the pill could affect you in three different ways:

  1. Ovulation will be prevented if you haven’t already started ovulating (the egg will not be released to meet with the sperm. Sperm can survive in your vagina up to 72 hours after intercourse)
  2. Your normal menstrual cycle will be altered, delaying ovulation (the release of the egg from the ovary.)
  3. If the egg has already been released, the lining of your uterus will become irritated, and this irritation will interfere with the ability of the fertilized egg to implant in your uterus. (Your body will reject the baby, and he/she will die.)
