I had sex on Febuary 28th coming off my period, and then on March 2nd with the same guy. I then had sex on March 8th around 12 so really march 9th. he didn't go inside me. My due date is decemeber 5th and i counted back 40 weeks and i would have concieved on the 7th of march. i'm trying to figure out who the dad would be? if that's when i concieved then there's no way it could be the second person because we wouldn't of even had sex yet. what do you guys think? i know to take a DNA test but who's more likey to be the dad?
