When did u do it with guy #1 if none after guy #2 then I would think it would be his. Unless it was both within a 1-2 day period.
I would love to help you on this but since the dates are so close to eachother its really hard to tell. I know you would prefer to know who the father is but it seems to me your gonna have to wait till the baby is here && do a dna test. How far along are you ?
