Plan B is about 95% effective in reducing the risk of pregnancy if taken within 24 hours of unprotected sex, 89% effective if taken within 72 hours following unprotected sex.
Plan B can cause your next period to be start earlier or later than is normal for you. If you don't get your period within three weeks, get a pregnancy test to make sure that you're not pregnant.
