Hello, hopefully someone can help me. So on February 4th, my boyfriend and I had unprotected sex. He did ejaculate inside me, but after a couple of hours we went and bought an emergency contraceptive pill. I am not supposed to get my period until February 25th, but today, i started to get cramps and bleeding. I have taken emergency contraceptives before and they have never messed with my cycle. Could I possibly be pregnant?
