A prenatal ultrasound is a common procedure that takes place during the first, second, or third trimester of pregnancy. While this procedure is non-invasive and painless, it is normal to have some reservations before the appointment with your gynecologist. This guide will address your concerns by explaining the process in more detail.

What is the Purpose of an Ultrasound?

A prenatal ultrasound utilizes sound waves to create an image of the shape of your baby in the fetus. Gynecologists perform this procedure to check the baby’s sex, growth rate, heartbeat, and expected delivery date. Your gynecologist can also use these images for the early detection of potential complications. 

In addition to the commonly-used transabdominal ultrasound, there are other kinds that offer more specialized results.

• 3D Ultrasound: This provides more life-like images of your baby. Doctors can use these images to examine your baby’s physical appearance in more detail. To ensure that your baby is developed enough to get an accurate image, this procedure should take place between 24 and 34 weeks.
• 4D Ultrasound: This creates continuous images that help monitor your baby’s movement. During this procedure, you may be able to see your baby blinking their eyes or sucking their thumb.
• Fetal Echocardiography: This allows you to see your baby’s heart in more detail. It is mainly used for early detection of possible congenital heart defects.

What Happens During the Procedure?

Depending on the type of ultrasound, your gynecologist may ask you to come to the appointment with a full bladder since the fluid sometimes improves visibility during the procedure. This applies to ultrasounds performed in the early stages of pregnancy before the 24th week. 

During the procedure, you will lie on a padded examination table where your doctor will rub a clear gel on your belly. They will then move the transducer, which emits sound waves, over the gel. These sound waves enter your body, bounce off of your baby, and return to the transducer. The sound waves are then transported through a wire and transformed into an image on a screen. This process takes up to 30 minutes, is painless, and has no side effects.
