Who's the father?

[JDD123]

I am 21 weeks and 3days pregnant. My due date is May 13, 2014. I Had sex with my current bf at the end of July before I went out of town Aug. 2 nd I started my period Aug.2 nd ended Aug.6 when I returned home but with in that time period after Aug.6th I had sex with another guy and my current bf but I got conceived Aug.20th so which is most likely the father my current bf or the one I cheated with? But me and the other guy used a condom but me and my bf always had unprotected sex

Hmm.  Well, 14w3d is not the very best timing to have an ultrasound if you want a reliable conception date, as it is well past the point where doctors will say "plus or minus a week" when giving a date.  Babies all start out as one cell and then move to two and then to four, but by the time 9 or 10 weeks rolls around, they can begin to diverge from the average in terms of size, and by 12 weeks some doctors even say "give or take a week or two" (though two weeks off the norm at only 12 weeks seems a bit much).

The conception calculator I use says your likely window of conception is August 16 to 24.  If you were having sex with both guys during that time period, it is anyone's guess whose the baby is.  Condoms are not 100% effective, unfortunately.

I got the due date from my OB/GYN doctor from when he did an ultrasound on my first doctors visit and he told me i was 14 weeks and 3 days

Hi, JDD, did you get the due date from an ultrasound?  If so, when was the ultrasound (how early in the pregnancy)?

My due date is May 13, 2014

Maybe your bf just got you on a fertile day but the only sure way is a DNA test. Good luck

Do you have an estimated due date from an early ultrasound?
