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.
