Ultrasound and Pregnancy: The Third Trimester

The third trimester of pregnancy can be a kick in the ribs – literally! As the newest member of your family grows and moves, the closer the crown of the head moves toward the birth canal. This is something of a slow somersault. Often times, it’s noticeable by the kicking-in-new-places.

But sometimes it’s not readily obvious. This doesn’t necessarily mean anything is wrong, but that may be a moment when your doctor would order a third trimester ultrasound.

Here’s What To Expect:

Third trimester ultrasounds are less common but not unheard of. Just as during the first or second term ultrasound, measurements can be taken to confirm size and due date.

Here’s What You’ll See:

This ultrasound can be used to look for fetal development, size, fluid and position.  The examination is typically performed by scanning with the probe on mom’s abdomen.  It is uncommon to perform transvaginal fetal ultrasound during the third trimester.

So, if you don’t need a third trimester ultrasound – that’s totally fine. As doctors we try to be judicious about the use of imaging. Again, while an ultrasound is harmless, why go in for unnecessary tests? If your doctor does recommend a third trimester ultrasound, again – don’t worry. We simply want the best possible health – for all!
