I took the plan b pill 11 days ago now i have this brown discharge but my period isn't due for another week or two what's this mean?

Took too late?: You may be pregnant. Take a home pregnancy test to be sure.

Plan B: The brown discharge is likely old blood being cleaned from the uterus. Plan B can alter your menstrual cycle. 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.
