When Is an Ultrasound Performed During Pregnancy? An ultrasound is generally performed for all pregnant women around 20 weeks into her pregnancy. During this ultrasound, the doctor will confirm that the placenta is healthy and that your baby is growing properly in the uterus.
The ultrasound is called a nuchal translucency (NT) test and can be performed when you are between 11 to 14 weeks pregnant. This measures the fluid under the skin at the back of the baby's neck and can be used to determine your risk of having a baby with Down syndrome.
