My boyfriend and I had unprotected sex on what my calendar said was peak/high fertility. That was Friday night into Saturday morning. We talked about it and anything was good but Sunday evening he gave me a plan b pill and asked me to take it. I did and about 30 minutes after got pretty bad cramps like I thought about going to the hospital but the next day they weren’t as painful. It has been a week since all of this has happened and I still have cramps and the pain hasn’t changed. Has this happened to anyone and what should I do?
