I had unprotected sex about 5 days ago. It was thursday. Friday I git the morning after pill. My boyfriend didn't finish in me though. I was at that stage already 3/4 days late. It was exams the week before so I had alot of stres. But there were menstrual symptoms like tender breasts. Today is Tuesday. I hadn't start with my period yet! Should I worry?? I'm 8 days late!!
