Confirmation

[kls1023]

Hello my LMP was 03/13/2014. I had a fairly light cycle and had sex with guy A on 03/16/2014. I did not have intercourse again until 03/22/14 with guy B. Guy B was the only guy I continued to sleep with. My cycles are regular and normally come every month between the 10th and 17th of the month. I had an ultrasound 05/27/14 which showed I was 10.5wks pregnant which matched exactly with my LMP. According to this ultrasound I ovulated somewhere between the 26-28 of March when I got pregnant. All my ultrasounds so far throughout my pregnancy have matched up within a day or 2 of my LMP. Based on this info would guy A or guy B be the father?

Once the baby is visualized on an ultrasound, you don't have to puzzle over when your last period was or when your ovulation was.  The doctor saw the actual embryo and measured it.  That trumps all other information, the baby is the size and development level that it is, on that date.  That is what gives you your due date.

Thank you so much for your response. One other question if I ovulate early would that change my due date?

[AnnieBrooke]

It all points to Guy B.

Yes it was 12/18.

Did your earliest ultrasound give you an estimated due date?
