A member asked:

Do fetuses in the 1st trimester measure the same or can there be a wide variation in mm?

A doctor has provided 1 answer
Dr. Liza Kunz answered

Normal range: There is no exact normal measurement at any gestational age. There is a range in which measurements are considered normal. If you are outside of that range the pregnancy may need to be redated.
