When and Why to Get Ultrasounds During Pregnancy

Posted March 8, 2023 by in Health + Fitness

Pregnancy is a unique experience that comes with its own set of joys and challenges. One way to ensure that the pregnancy is progressing as it should is to undergo regular checkups and ultrasounds.

Ultrasound is basically a small test that uses sound waves to produce images of the developing fetus in the womb. These images can provide valuable information about the health of the baby and the mother. In this post, we will explore the basics of pregnancy ultrasounds, the benefits of getting them, and when they should be done.

Let’s get started!

Pregnancy Ultrasounds: The Basics

As mentioned earlier, pregnancy ultrasounds are a type of medical imaging that uses sound waves to create images of the developing fetus in the womb. The ultrasound machine sends high-frequency sound waves into the body, which bounce back and create an image on the screen. It is a non-invasive, safe, and painless procedure for both the mother and the baby.

Now, there are three types of pregnancy ultrasounds: 

  • 2D baby scans: These are the most common type of ultrasounds and they create flat, two-dimensional images. The images produced are black and white in color and show the baby’s internal organs and structures. Moreover, these are usually used to confirm the pregnancy, determine the gestational age, and identify any potential issues.
  • 3D baby scans: These create a three-dimensional image of the baby, providing more detail and depth than 2D images. This type of ultrasound can show the baby’s facial features, such as the nose and mouth. Hence, it is often used for diagnostic purposes, such as identifying any facial abnormalities.
  • 4D baby scans: These are live videos of the baby in real time, allowing parents to see their baby moving and even smiling or yawning. This type of ultrasound provides more detail and depth than 3D images and is often used for non-medical purposes, such as creating keepsake videos or photos. 

In comparison to 2D and 3D scans, 4D baby scans expose babies to greater energy. Hence, even if you decide to spend a fortune on 4D scans (they cost up to $500), do it only once in the nine-month long pregnancy journey.

Apart from the differences mentioned above, it is also worth noting that not all of these baby scans are available at all facilities. 4D baby scans are the latest version of ultrasounds and demand the latest expensive tech. Hence, these are only available at a select few well-established medical facilities.

Why get pregnancy ultrasounds?

The primary purpose of a pregnancy ultrasound is to ensure that the pregnancy is coming along as it should. It allows healthcare providers to:

  • Monitor the growth and development of the baby
  • Identify any abnormalities or complications in the womb
  • Check the position of the placenta and the amount of amniotic fluid

If desired, ultrasounds can also help to determine the gender of the baby.

In this way, pregnancy ultrasounds help identify any potential issues or abnormalities early on. This can allow healthcare providers to take the necessary steps to ensure the health and safety of both the mother and the baby.

When to get pregnancy ultrasounds?

During a healthy pregnancy, it is recommended to have two ultrasounds only. The first ultrasound is usually done between weeks 8 and 14 of the pregnancy, and the second ultrasound is done between weeks 18 and 22. These ultrasounds can help to determine the due date, monitor the growth and development of the baby, and identify any potential issues.

In cases where the pregnancy is high-risk or there are concerns about the health of the baby or the mother, your doctor may recommend additional ultrasounds. For example, if the mother has gestational diabetes, she may need more frequent ultrasounds to monitor the baby’s growth.


Summing up, pregnancy ultrasounds are an excellent means of monitoring the health and development of the baby. They are safe, non-invasive, and provide valuable information about the pregnancy.  

If you decide to have a 4D ultrasound, keep in mind that it is not medically necessary. But it can be a fun and exciting way to see your baby in real-time. Always follow the advice of your healthcare provider, and don’t forget to enjoy the journey!
