Customer Question
OB/GYN Dr only please. Paternity...
OB/GYN Dr only please. Paternity determination via dates with no uncertainty. Dates pertain to 2016. On 8/31/16 I had a miscarriage. Just adding because I don’t know if it could matter. 10/13/16 sexual encounter with one partner. Sole encounter. A week later encounters with partner number 2 which continued for next two months. 12/29/16 transvaginal ultrasound puts me at 8 weeks 2 days. I understand this puts me ovulation on or around 11/15/16. Is there anyway factoring absolutely everything in that the pregnancy could have resulted from the 10/13 encounter? Including late implantation, how long sperm can live in the female genital tract, margin of error for first trimester ultrasounds, possible human error, measuring smaller etc. I read somewhere that the machinery used could affect the accuracy....but even with a really terrible one could it make be a month off? Or 3 weeks off if you factor in sperm surviving inside for 7 days? The only reason I am still so worried is the baby looks identical to me. So off looks alone there is absolutely no indication.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
