A member asked:

I had an early ultrasound on 01/15/14 baby measured at 6 weeks. did i conceive nov 9th or 12th?

5 doctors weighed in across 2 answers

Ultrasound guesses: Ultrasounds are only accurate 10 days to 2 weeks and aer not the best way to determine dates of conception.

Dr Fowler and 2 doctors agreed

Either could be: Ultrasound is not accurate to the exact day but to a range of dates. It cannot distinguish a 3 day difference in age.
