girl saids she has sex with boy june16th,2011 and due march 26th,2012
doesnt add up if due 26 she couldnt have conceived at that time.
i think she conceived at end of june upto july4.2011.meaning she would have had to be with another partner.
I don't know that's like 20 days off. Even if the semen lasted like 5-7 days, which would be the most it could last you'd still be off by like almost 2 weeks. If her due date is 100% correct I'd say there's slim to no chance. BUT really you can't tell until you take a paternity test. And anytime you have sex with someone there's the chance of pregnancy and you so you have to own up to the possibility that you could be the dad.
