The viability scan is the first scan of pregnancy.
Although this scan can be done from 6 weeks, we believe it is best to wait until at least 7 weeks if you have no concerns because it will allow you to see the early anatomy which will make the scan even more reassuring. `The viability scan is an ultrasound examination performed early in pregnancy.
The scan checks that the pregnancy is growing as expected in the womb. The scan will also tell you if you have one or more babies. The early baby at this stage is called an embryo. We will check for the heart beat and measure the length of the baby, this is the crown rump length. This measurement determines the gestational age. It establishes how old the pregnancy is and can give you your due date.
We may see the yolk sac, which is a circular bright structure that is the baby’s initial nutrition supply. The scan can be done through the tummy (transabdominal). The scan lasts around 20 minutes. You will get a printed report included.
