Okay Feb 26 or 27 of 2018 i had sex with my ex and he nutted in me. Feb 28 2018 was "supposedly" my last period. Well i thought it was my period not sure. It was very light spotting. Then on march 8, 2018 i had unprotected sex with someone, literally a quickie as they call it. But he was the pull out method which i saw on his hand. Maybe like 3 to 4 hours later i had sex with my ex again and he nutted in me again. Then i found out around 2 weeks after maybe like end of march i was pregnant. Im pretty sure my ex is the father but need other opinions.
