My boyfriend and I split up in December of last year and got back together mid January this year. Problem is, I found out this April I was pregnant (the doc said around 10 weeks) and while me and my guy were separated I ended up fooling around with my ex. Now the doc gave me a due date of Dec. 2 and the last time I slept with my ex was Jan. 1st. I actually ended up having my son on Nov. 27th. Question, is there any possibility in the world my ex fathered my son? Or, should I just kick myself for allow there to be such a close call?
