A dating scan is an ultrasound scan to determine how many weeks pregnant you are and your due date. During your pregnancy, you will be offered a number of tests and scans. You can estimate the due date of the baby by using our pregnancy calculator. You may have had a pregnancy scan recently which shows that your baby has a club foot or feet.
For instance, the EDD for a pregnancy that resulted from in vitro fertilization should be assigned using the age of the embryo and the date of transfer.
