1st trimester sonos: Pregnancy sonograms performed by a skilled certified sonographer between 6 and 14 weeks are very reliable "dating scans" and can help determine the gestational age with fairly good accuracy and estimate the expected date of delivery. Sonograms performed later in the 2nd or 3rd trimester are still useful but are not as accurate.
