Possible conception date?

[Bethy86]

May 24th 2015 I was with a man, then again on June 13th 2015 I was with someone different. I tested positive for pregnancy on June 29th 2015. Also I do not remember my last menstrual period, I do remember bleeding on the May 30th 2015, but now that I think about it I don't know if it was implantation bleeding or a regular period. I've had multiple ultrasounds that range from March 2nd to March 7th.  My question is, what man did I get pregnant by. The first or second? How accurate are ultrasound dating? And is that 3 week gap big enough to tell which man impregnanted me?

Hi, Bethy.  Those early ultrasounds are pretty conclusive that the dad is the guy on June 13.  The three-week gap is enough, given your early ultrasounds, not to have to wonder.

My earliest ultrasound was dated for March 4th. And I was less than 8 weeks along. And I had an ultrasound at 12 weeks and it dated me for March 3rd.

If your due date is march 7 i would GUESS with not much details you got preggo on june 13th.

Hi, how early in your pregnancy was your first ultrasound that gave you an estimated due date, and what was that date?

[Bethy86]

My earliest ultrasound was dated for March 4th. And I was less than 8 weeks along.

At 12 weeks I was dated for March 3rd.
