The first day of my last period was December 28, 2016 and lasted til the 31st with some spotting on the 1st. I had a one night stand on the 1st and 3rd of January, 2017. We had unprotected sex and he claims to not even *** while we had sex. Which I believe cause he wanted to keep going while I told him to stop. I was separated from my boyfriend the whole month of December til January 8th, 2017. The day we got back together he came inside me every day from then on. I believe the father of my baby is my boyfriend (now my husband). He knows I had sex with someone else and is always doubting that he is the father. My due date is October 1st. If I count 38 weeks back it lands on the 8th exactly. I really wanna believe he is the father. But I know sperm can live inside you up to 5 days. So that basically means the one night stand could still be a possibility. I guess I just need some reassurance or some input as far as what everyone thinks who the father is. Thank you.
