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 evidence suggests that ultrasound is more accurate than the last menstrual period date in predicting when the baby will be bornâbut only in the first trimester (weeks 1 through 12) and early second trimester (until roughly 20 weeks.) During the first 20 weeks of pregnancy, the margin of error is roughly 1.2 weeks.
