"I had unprotected sex and he ejaculated completely inside me. About 38 hours later, I took the pill with food and water. I was expecting my period about a week from that day. Throughout the whole time waiting for my period I had absolutely zero side affects, and it really really worried me. It was about 2 weeks after I took it that I finally got my period, and I was never so happy to be in so much pain."
