The due date scan is usually the first ultrasound scan in pregnancy. Ideally it is made between 10 and 12 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 than 10 weeks but could be less reliable if made too early. Your midwife will send a referral for this scan so the insurance will cover it. The insurance will only pay forone due date scan though so if you come too early the first time you will have to pay for the second scan yourself.
