Family Planning Plus

Your period may be starting, depending on your cycle. You may be having irregular bleeding.

Plan B helps prevent pregnancy by delaying ovulation. After taking it, you may experience some irregular bleeding or spotting until your next period. Your next period may be a little earlier or later than usual. It may be lighter, heavier or spottier than normal. If you do not have a period within 3 weeks of taking Plan B, do a pregnancy test.
