need help ? any idea what this could be ?

alright ; so i'm not suppose to start my period for another 2 weeks. i am on birth control, i'm taking the pill. well ; i had sex with my boyfriend yesterday around 5p.m. and about an hour and a half after that i started having a brown discharge. a lot comes out at once. i'm having lower abdominalcramps, every once in a while.i don't know what it is, or what it could be. has anybody ever had something like this? any idea what it could be?

just sounds like blood.... prolly period

It sounds like just your normal period blood. Sometimes I bleed a little bit aday or two before I actually start my period.

If its brown discharge then its probably just old blood.you may have bled a little early from having sex.I wouldn't be worried about it.

thank you
