I've been on Microgestin FE 1/20 for a little while now. I'm almost done my 2nd packet and on my 1st packet my boyfriend and i had sex alot and he came inside of me alot and i still got my period. but on my second packet im on my last week of pills and i havent gotten my period yet. i've been taking my pills religiously, meaning i haven't missed a day. i've been a few hours late to take them only a few times. is it possible that i am i pregnant?
