I recently started birth control on July 10th and my boyfriend came in me like 3 times before I had been taking it for a week. What are my chances of being pregnant? My period is very regular but now it's messed up because I just started birth control. I took two pregnancy test a week ago and they came out negative. Would that pregnancy test count for those times? I took it then because that's when my period was due but I never got it due to starting birth control
