A member asked:

Looking for second opinions please with someone with a due date of august 29, 2013 according to 6 week ultrasound conceived from sex in nov or dec :-)?

A doctor has provided 1 answer

Likely: This would correlate with conception around 12/ 2-10. This is not an exact science and is based on a 28 day cycle. First trimester ultrasound is accurate within 5-7 days. 2nd trimester ultrasound has accuracy of +/_ 2 weeks. . There is no test that can date conception more accurately than a 1 week window.
