Wellbeing Ultrasound


  • Third trimester


The purpose of a Wellbeing Ultrasound varies depending on your pregnancy, but often are used to:

  • Evaluate the growth and health of the baby/babies
  • Confirm the baby's position in preparation for delivery
  • Measure the size of the fetus and estimate fetal weight
  • Examine movements of the fetus
  • Measure the amount of amniotic fluid


Not all women need ultrasounds in their third trimester. Your doctor may refer you for a 3rd-trimester ultrasound if there are signs of increased concern for you or your pregnancy or childbirth.

Your doctor may want you to have a 3rd trimester ultrasound if:

  • You have had previous complications of pregnancy such as pre-eclampsia, growth restriction, diabetes, or stillbirth.
  • You have a multiple pregnancy (twins, triplets).
  • You are concerned about the movement of your baby/babies.
  • There is concern that your baby has stopped growing.

Sometimes done in a series

If you have a higher-risk pregnancy, your pregnancy care may include a series of ultrasounds as we keep close watch over the health and development of your baby (or babies).
