So I'm 16 and on the pill. Me and the guy I'm with have had sex 4 times in the past couple months I've had my period since we started having sex. But I've been on my sugar pills for 3 days and haven't started bleeding yet. Today I had really bad cramps which I usually get before/during my period. Last time we had sex was 3 days ago and we didnt use protection and he didnt cum in me. So idk if I'm just paranoid and my body is weird or if I'm pregnant.
