I'm on birth control and have been for quite sometime. I take it everyday at 8:00 pm. If I'm ever late it's maybe an hour max. I have an ap that tracks when I'm fertile and when I'm ovulating. During that time of the month my boyfriend doesn't go inside me just for extra precaution (since I am on birth control). I am supposed to start my period next thursday and I am having extremely sore nipple. It's really weird because I've never had tender breasts or nipples before any period. The only time I had tender breasts was after I had my son and I was nursing. Do you think maybe I could be pregnant even if a pregnancy test says no? I'm just worried that I have one more week on my birth control and I could be pregnant. If I am I wouldn't want to risk something by taking medication.
