Okay.. this may be a stupid question so I'm sorry. I've been on the pill for two years now. I've only missed a day maybe twice(nothing recent) and Monday was the start of my period. Well my period only lasted Monday to Wednesday and I had a dark red/brown discharge. Well I had unprotected sex Thursday (no he didn't come in me) and yada yada. Well I started my pill again on Sunday and saw a little pink discharge in the morning? Didn't get any more throughout the day... And I woke up again today, took my pill, went to the bathroom and saw more light pink discharge?? It's only been four days since I've had sex and my period was supposed to be over??? What is this light pink discharge? Does it mean I'm pregnant even though I've been on the pill for two years? And he also didn't come in me??? Help
