Yeah, you're going to have to have a DNA test done. We can't determine who the father is for you. :/
well i had a situation like this once with my oldest son, my ex boyfriend and i were still messing around and i was seeing someone else on the side i know dirty girl, but the best way i can answer this question is your going to have to wait till baby is born with the time frame beng so close it is hard to say and sperm lives inside the female body up to 5 days pending on how fertile you were at the time on intercourse. i once heard to if multiple men's sperm is in the body the sperm does fight each other there dna dont mix, but i dont know if that is true, in my case my ex turned out to be the father and he was the one i slept with after the fling. fling was april 3,5,7 and ex was 8-17th conception date was april 14th wow i cant believe i remember that after 7 years lol, i wish you luck sorry i could not be any more help but really you are going to have to wait till your little one is born and dna testing can be preformed. good luck
