  • “How many ultrasound scans do I get on the NHS during pregnancy?”
Updated by Maria Birch on 20/02/21

In a normal, low-risk pregnancy—which is the case for most people—you will be offered two NHS scans.

The first scan will be between 11 and 14 weeks gestation. The second will be around 20 weeks gestation.

All being well, there will be no need for any other NHS scans after that.

There are many reasons, however, why a pregnant woman may go on to have further scans.

It may be, for example, that the pregnancy is deemed high risk due to maternal health problems. That includes complications in a previous pregnancy or if an abnormality has been detected in this pregnancy.

From 24 weeks, after the two routine scans, your midwife will periodically measure your baby bump and, if she feels there is any discrepancy in babies size—either you are measuring small or large for your dates—you may be offered another scan.

Finally, you may need extra scans in the third trimester if you notice a change or reduction in baby’s movements. Those performed in the third trimester are called growth scans.
