So I'm on birth control pills and I missed one day and I took the next day pill an hour or two later than when I usually take them. My boyfriend has been finishing inside me since then and it was the first week of my pills (I've been on the pill since last year, I mean it was the first week of a new pack) and now for some reason I have HORRIBLE cramps I feel sick and I'm bleeding it's basically a period I wear a tampon but it's not as bad and heavy as my period usually is and the blood is super clotty.. help what could it be ?? Could I have gotten pregnant and these are super early symptoms
