About this episode

This episode discusses the role of ultrasounds during pregnancy, including safety, accuracy, and what to expect at different stages.

Ultrasound during pregnancy is one of the most common tools your care provider uses to monitor your baby's health and development. Whether it is your first scan in the early weeks or the anatomy scan in your second trimester, ultrasounds provide valuable information about how your baby is growing. However, many expecting parents have questions about how many ultrasounds are necessary, how accurate the measurements are, and whether there are any risks. This episode walks you through what to expect at each stage of pregnancy, from the first-trimester scan to third-trimester growth checks. Hear about the research on ultrasound safety, what professional medical organizations recommend, and how accurate ultrasounds are for estimating your baby's size. Plus, 3D and 4D ultrasounds, home Dopplers, and what happens when an ultrasound reveals something unexpected. If you want to feel informed and confident heading into your next ultrasound appointment, this episode will help you get there.
