Hi I'm just curious about a few things that have been occuring with my discharge frequently lately I am 17 and am on birth control I had recently had unprotected sex and made sure to take plan b the day after just to make sure I didn't get pregnant. But what Was weird was I got my period mid way through my birthcontrol packet which didn't seem right. It has been about a week since my period and I am still hAving brown discharge is thAt normal? Or could there be a chance that the plan b did not work?
