One of the most common side effects of Plan B use is menstrual irregularity. Therefore, your next period could be heavier than normal, earlier than usual, later than usual, or spotty (meaning you may bleed for a few days, stop, and then bleed some more). If you normally have a 28-day cycle, your period should come around March 1 (today).
If you are more than one week late for your period, take a pregnancy test. If it is negative, repeat the test every two weeks until you either have a normal period or a positive test result. Unfortunately, Plan B is not 100% effective and you can still become pregnant.
Just remember that Plan B should not be used as a regular method of birth control as it is less effective than other methods. If you are going to continue to have sexual intercourse, it is best to use another more reliable form of birth control. If you would like to discuss your birth control options, please call one of our clinics to make an appointment. If you live too far away, contact the Family Planning or Planned Parenthood office closest to you.
