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.
A common use of ultrasound in early pregnancy is to calculate a gestational age. For this purpose, an ultrasound is considered a highly accurate means of dating a pregnancy. In a normal pregnancy, the ultrasound results can provide an estimate of the gestational age to within five to seven days of accuracy. When a woman is having miscarriage symptoms, a doctor may order one or more ultrasounds to determine the viability of the pregnancy.
