So I had unprotected sex 3 days after my period. (Monday evening) My partner was certain he didn’t ejaculate in me however just to be on the safe side I took the morning after pill. (On Thursday evening). Since taking the pill by Friday I began to feel cramps and started to get very very gassy. Today is Saturday and I’ve been feeling gassy all day constantly having to excuse myself to the bathroom. Could these be very early signs of pregnancy?
