I'm 38 weeks pregnant, i know..about to pop..but this is still eating me alive.. Me and my boyfriend broke up before new years, i went to a new years eve party, drunk a little..i don't remember doing anythingggg at all with a guy (my friend said i didn't either) btw, i was on my period.. i started either dec. 27th or 28th..anyways me and my boyfriend got back together and we had unprotected sex on Jan 10th, and the 13th.. and if i'm calculating it right i would have been ovulating around that time.. which when i had sex with my bf it was unprotected and he didn't pull out.. the only thing that's bugging me is i found out reallyyy early.after i had sex with my bf, i just felt off.. i took a pregnancy test multiple times each time it was a negative. I took a digital test on Jan. 21st and it was a positive. So i found out i was pregnant 11 days after i had sex with my boyfriend..On my ultra sound i'm due Oct. 2nd.. and that puts my conception date on jan 10th, which was my boyfriend...Like i said i'm almost 100% sure it's my boyfriends, i just want others imput..is there any possible chance that if i did do anything with someone at that party, could it be their baby?  any opinions help.. thank you!!
