Baby dating scan accuracy

At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound.This can be for many reasons but the most common is to confirm pregnancy and to check that the embryo is viable and “everything’s ok”.Even when the last period is known, ultrasound is reassuring to demonstrate adequate growth, especially when there’s a risk of delayed growth, as in hypertension or smoking, or if there’s the risk of exaggerated growth, as in gestational diabetes.It is not uncommon for babies that are labeled “Large for Gestational Age (LGA)” and “Intra Uterine Growth Restriction (IUGR)” to have monthly or even weekly ultrasounds during the pregnancy.When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done.

Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period (as in breast-feeding or irregular cycles).

Having a scan in the first few months of pregnancy can be a thrilling experience.

It's amazing to see the little blob with a heartbeat that will soon become your baby.

You may have calculated the length of your pregnancy from the first day of your last menstrual period (LMP).

This is even though you don't actually conceive until 14 days after your LMP, or later than this if your cycle is longer than 28 days.

The limbs and the yolk sac, though obviously important, are not the primary means of measuring growth.
