A member asked:
If lmp and first trim scans all point to same edd, is the conception date range accurate?
A doctor has provided 1 answer
Yes: If your dates and ultrasounds are consistent the estimated conception date should be reliable within a few days. Short of tracking ovulation with daily ultrasounds or one of the in vitro methods, that is the best we can do.
