Alright so March 27th my boyfriend and I had unprotected sex, he came in me. Later on that day (it may have been early the 28th) we went to get plan b. I took it, got my period April 8th then him and I had unprotected sex again and he came in me (shoot me now) because I know when I ovulate. Is it possible that plan b changed my ovulation and I may be pregnant?
