To continue on Vedran's point...

A woman generally knows if she is pregnant anywhere from two weeks to a month after the deed, simply because of biology. He would have had to be a one night stand and left immediately. Then she had to find another guy some time between 1-3 months after she had a one night stand, and then do all the stuff Vedran said.

It would be more believable if the dad knew the kids weren't his but accepted them anyway, because he's a nice guy.
