[|Human|] My girlfriend is on Loestrin 24 Fe birth control pill and has been for probably 8 months. She takes it religously. We recently had sexual intercourse and I was not wearing a condom but I pulled out before ejaculation. She had her period a week before sexual intercourse, and now, 1 week later, when she is taking the placebo pills and supposed to have her period she isnt. Whats the deal?
