Quoting sara77*:" Kaaw--- thats what I think, too. B/c if I would've conceived when he says I did.. I keep coming up with a due date at the beginning of August?! That's why Im soooo confused. "
pregnancy lasts 40wks that is the very last day of the 9th mo. so say 10mo to be exact then dont forget 2wks after your period for the egg to drop and be ready to get "spermed" for a total of 10mo and 2 weeks.....my calculations could be wrong though. but i would go with the doctor and say it's the ex's baby.
