Dr. Miguel Cano answered

Specializes in Obstetrics and Gynecology

Ask your Doc: An ultrasound date of 9 weeks is fairly accurate so your doc can extrapolate backwards and calculate when you most likely ovulated and which days you most likely conceived. For example, if you were 9 weeks today (11-14-2012) you most likely conceived around 9-26-12 (7 weeks ago). Remember conception age is always 2 weeks less than the gestational age we calculate. Take care.
