Ideally the 1st scan which is you dating scan which is taken as your due date. The fetal age will be measured to correspond with it and to figure if there's any IUGR(intrauterine growth restriction). If you NT scan came back as normal with the right levels of amniotic fluid and no other abnormalities you don't need to worry. I would suggest you to follow up with your OBGYN regularly as your age is considered as high risk during pregnancy.
