The due date scan is usually the first ultrasound scan in pregnancy. Ideally it is made between 10 and 11 weeks to determine the gestational age of the embryo and set the due date. We will also look for a heartbeat and check if there is one embryo or maybe more. This scan can be made earlier or later but could then be a bit less reliable. Your midwife will send us a referral for this scan so the insurance will cover it. The insurance will only pay for one due date scan.
