I had unprotected sex a few days before my last period with a Guy used to get back at my was then ex boyfriend then the day after my period ended me and my ex got back together and had sex the same day... I took a hpt two days after my missed period and it came back negative I took another test a week after my period it came back positive with a faint line. I took a digraph one a few days later it came back pregnant.I just want to know if it is even possible if it could be the other guys?
