Me & a lady had a one night stand on August 27, 2012 . She then later had sex with another guy on September 27, 2012 she is still with him & they now had a baby on June 27 , 2013 . Could I be the father of the baby ?
No, you are not the father if she had a baby on June 27. The baby would have to be 5 weeks overdue for you to be the father, and babies are never that overdue.
