A member asked:

Sex dec. 31 jan. 4 and jan. 16 got a positive pregnancy test jan. 21 both us i had pointed to the first 2 dates at my 8 an 12 week appt. how accurate?

A doctor has provided 1 answer

Earliest ultrasound : Doctors use last menstrual period as a dates guide, but the earlier you have an ultrasound, the more accurate it is. If you had an ultrasound back at 8 weeks, it's the best indicator for accurate dating.
