okay so my boyfriend and i had sex about a week ago. we had it 4 times in one night. i know it was crazy. the condom broke one of those times. i'm on the pill although i've been a little lazy with it lately, not taking it at the same time each day but it was like 3 days after my period ended. anyway, i took the emergency contraception pill 2 days later and now i'm getting this brownish period-like discharge? i know the chances are slim but i just want to know if this is a sign of pregnancy. thanks.
