So I am 24 and 4 days pregnant I had sex with my ex 31 weeks ago. Then I had got back together with my current boyfriend 29 weeks ago. We had sex several times unprotrcted. My last period was 27 weeks ago. It lasted from around may 25th to the beginning of June. (Dont remember the actual dates) which means that gives me 3 weeks after my period and then I was a weeks pregnant. COULD MY EX BE THE FATHER??
