I have been on aviane-28 birth control pill for almost a year. I take it about the same time every day. I had unprotected sex yesterday, July 15, and he pulled put long before ejaculation. He also hadn t ejaculated in days before then and urinated many times since last ejaculation. My question is, what are the odds of me being pregnant if he didn t ejaculate anywhere near me, no sperm in his Pre-ejaculate, and I am on the pill?
