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.
Two ultrasound exams are performed over the course of your pregnancy-one in the first trimester and one in the second. 1  The first trimester ultrasound is used by health care providers to confirm and date the pregnancy, so you will get a fairly accurate idea of your due date.
