While you are cooing over the tiny little figure, the sonogapher will accurately date your pregnancy, look for any abnormalities and make sure your baby is developing correctly. As the embryo matures to a foetus, individual genetics and growth factors influence its growth. Didn't get the email? The person performing the scan is called a sonographer. A dating scan might be recommended to confirm your due date if you are unsure of your last menstrual period or your date of conception. These can be carried out from week 5 or 6 of pregnancy, which is a notoriously tricky time to be accurate on dates.
But, assuming your pregnancy is healthy, you'll still have the dating scan at round about the week mark.
What to expect during your first scan
I agree to the Conditions of use. But it is important to remember that only a few women go into labour on their due date, so it can be more helpful to think about the month in which you are expecting your baby, rather than the exact day. This is also more likely if you are having a transvaginal ultrasound. So obtaining accurate measurements and visualising them clearly on the screen is a little easier than when they are able to do somersaults and move around a lot. Your sonographer will let you know if this is needed. The week scan is the first in-depth look at your growing baby and assesses the early development in the womb.
