If you had a + opk on Tue, and slept with your hubby twice, and then the other man on the Friday, it is a very high chance of being your hubby's baby....it is very likely you already had a fertalised egg before seeing the other fellow...

I'm not sure how early you can get DNA done??? With an amnio I suspect...

I guess you have to weigh up the risk of hubby finding out anyway, (they usually do), terminating the other mans baby, or worst senario, terminating a much wanted baby concieved with your hubby....

Hon, I really feel for you and your situation, and passing blame now doesn't help anyone...

Just in my opinoin, I'd keep bubbs. It is very likely Dh's, and if its not, its still your bubba.

But you must do what is right for your own situation.
