I had sex with my mistress last Nov. 20 and Nov. 21 but she also had regular sex with her Bf every week aside from the date we had sex. Now we had an ultra sound results that said on Jan. 03, 2014 she is 7 weeks and 2 days pregnant. Who do you think is the father of the baby? By the way her LMP is Nov. 13, 2013.
Thanks
