Okay, this is probably important so ill tell you everything I can remember. so I had sex with my boyfriend and we discovered I'd started my period for that month whilst we were having sex. Id taken my pill the night before however. He pulled out literally just before he ****, so never actually **** in me. So the next day my period was heavy as usual. Lasts about a week and it finished around a week and a half ago. Yesterday I discovered I was bleeding a little; only light pink. And then this morning it was a lot heavier with no cramps (there was only blood if I wiped). Now I have cramps and I'm bleeding without wiping, so it's literally coming out of me like it does on a period. But I'm still taking my pill as I should be, so I don't see how this could be another period (which is what it feels like). So what could be wrong with me?
