I took a plan b last week. im spotting now and my period is supposed to come next friday. is this normal?

Yes: Plan b will change up the mestrual cycle since it works by preventing ovulation. Bleeding is expected. You should always take a pregnancy test afte rusing Plan B to make sure that it worked.

Side effect: Emergency contraception symptoms can include spotting or bleeding, changes in menstrual flow or your period may be late or early. Take a home pregnancy test & notify your GYN if your period is 7 or > days late.
