Hi, me and my fiancé are sexually active and she's worried about her chances getting pregnant. first off, she takes birth control pills for medical reasons. when she didn't take them, one of her ovaries stopped functioning and her periods were irregular, but she takes the pills to fix that. I don't know if taking it for medical reasons still prevents her from ovulating or not. I also use the pull out method, and she always used the Plan B pill every time just in case. So my two questions are; do her pills still work for not getting pregnant even with her condition, and if so, are the Plan B pills and pull out method even necessary?
