Lmp: 5/11. u/s on 7/23 dated 10w2d, edd of 2/16. u/s on 10/1 dated 20w4d. 1 partner before lmp, new partner after. can i be sure its my new partners?

Reasonably Sure: The early ultrasound confirms your LMP of 5/11. This gives an edc of 2/15 which is almost exactly what your 10 week ultrasound shows. This means, if your new partner was your only "exposure" after your lmp, he would be the father. You would have ovulated approximately around 5/25, so a partner before your menstrual cycle, doesn't have a chance of being the father. I hope that helps.

I had my period on April 9th. My periods are fairly irregular by a week or so. My ultrasounds measure two weeks behind my LMP due date. I've had one done at 5WKS (too small to tell), 6WKS5DYS, & 19WKS. They all gave me the same due date by except 2 days.
