Ok I'm on trifeme birth control, have been for 5 years and about 2-3 weeks ago I went out and didn't take my pill.. I didn't take it the next day either and I slept at my boyfriends house and we had unprotected sex a few times but I took my pill at like midnight that night and ive been taking it since and a few days after that night I started the red pills and I did get my period but just thinking could I be pregnant and I got my period because it was only a week at most after we had sex ? Has anyone else experienced the same?
