I need someone to put my mind at ease!! I had unprotected sex around the 13th Feb, he did finish inside me but I then had a period on the 2nd March that was very normal and heavy like always and lasted 5 days, I’ve had sex less than a week after my period with someone else but he pulled out but a possibility he didn’t do it on time, I’m now 10 days late and I have taken 3 HCG tests which have come back positive. Is there any possibility the first guy could be the dad ? Or am I being stupid ?
