I had unprotected sex twice but used ecp on third day of the first time and first day of second time I had sex. then after two weeks or three just day before yesterday I bled and thought it was my period because I was expecting it even though it came 6 days early but just lasted two days and I bled heavily and now on the third day there’s nothing. So I thought maybe it’s implantation bleeding or the breakthrough bleeding (bleeding after using ecp) because it can’t be my period, it’s never this s
