A member asked:
Are 11 week ultrasound more accurate for dating conception than 6 week ultrasound, both are transvaginal?
A doctor has provided 1 answer
Not necessarily: Due dating pregnancies is more accurate with more than one ultrasound performed. However, the 6 week ultrasound might be more accurate in dating your conception. Either way ultrasounds have a 'fudge factor' of 1 to 2 weeks in determining accuracy.
