A member asked:
Concerned about edd accuracy. is it possible for ultrasound measurements in the first try to be a month off? all of my edds have matched through preg.

Yes: If your doctor or technician made an error on your first tri ultrasound, then it would be possible for your edd to be wrong. If ur saying that every us you had after your 1st tri us agreed with each other and gave a different edd, consider discussing with ur doc to have edd changed. 1st tri us are most accurate, but you are right to suggest that person can make a mistake while performing.
