confused on who my unborn childs father is :(

if you are pretty sure u had periods then be sure its your bf's baby.

Hi mommytobe, I have to disagree here, I counted back 8 weeks from Sept. 12th, that would put your conception date at around the 18th of July, so....given that doctor's can be off by a week either way, (a week too soon, or a week later,) a week before would be the 11th...sex with the Ex, or a week later, which was the 25th, which you didn't have sex with either guy that day. Not to mention that you were ovulating the entire week you were having sex with your ex, and not the 30th when you were with your boyfriend. You wouldn't have had an egg for your boyfriend to fertilize on the 30th sweety. So, either your doctor is off on how far along you are, (which isn't hard to do when very early in pregnancy,) and will change your due date when you get farther along and have another ultrasound of your baby. Or, this is your ex's baby. Mind you this is just the opinion of someone who is the mother of 4, so been pregnant 4 times. Not a doctor by any means. I hope this helped. Good luck!
