I took plan b & i'm expecting my period soon;it's been 2 days since the pill &there's brown discharge..i usually get it before my period.is it coming?

Hard to guess: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time.

Plan B effect: Plan b is essentially taking a high dose of birth control to disrupt the hormonal patterns in your body to delay or present ovulation. An abnormal period afterwards is not surprising.
