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.
After 3 weeks, ultrasound is the most accurate and important way we monitor early pregnancy. A pregnancy can first be visualized as a collection of fluid (gestational sac) within the uterus about 18-23 days after conception.When we are worried that a patient might have a pregnancy in her fallopian tube (ectopic pregnancy), we will perform an ultrasound to see whether a gestational sac is in the uterus. pregnancy can first be visualized as a collection of fluid (gestational sac) within the uterus about 18-23 days after conception.
