Plan B works by either delaying or preventing ovulation, and by altering the cervical mucus to create a hostile environment for sperm. You might still have had the protective effects the next day.
Your period may be slightly delayed as a result of taking Plan B so close to when you were due. If your period is late by more than seven days, take a home pregnancy test.
