A member asked:

Can the first 2 ultrasounds of pregnancy taken a month apart with the same accuracy of gestational age in the second trimester be off by +- 25 days ?

A doctor has provided 1 answer

Dr. Cynthia Palabrica answered

Ultrasound: The earlier an ultrasound is done the more accurate it is. The due date should never be changed to the date received on a later ultrasound.
