Ultrasound is one of the most exciting and important parts of pregnancy. Not only does it let parents see their baby grow in real time, but it also provides doctors with crucial medical information. One of the most common questions expectant parents ask is: When should I schedule my anatomy scan?
This guide breaks down what to expect during each trimester and explains why the anatomy scan is so important.
First Trimester (Weeks 6–13): The Early Look
During the first trimester, an ultrasound is usually done to:
- Confirm the pregnancy
- Estimate your due date
- Check the baby’s heartbeat
- Rule out any early complications
This scan is typically done around 8–12 weeks, but it is not the detailed anatomy scan. At this stage, the baby is still too small to see organs clearly.
Second Trimester (Weeks 18–22): The Anatomy Scan
The mid-pregnancy ultrasound, often called the anatomy scan or 20-week scan, is the most detailed look at your baby. It usually happens between 18 and 22 weeks.
During this scan, the sonographer will:
- Measure the baby’s growth
- Examine the heart, brain, spine, stomach, kidneys, and bladder
- Check the limbs, face, and overall development
- Look at the placenta and amniotic fluid
- Sometimes determine the baby’s gender (if parents want to know)
This is the scan where many families first see their baby’s profile clearly. It’s also the point where doctors can catch important health conditions early.
Third Trimester (Weeks 28–40): Growth and Position
Not everyone needs another ultrasound in the third trimester, but doctors may recommend it if they want to:
- Check the baby’s growth and weight
- Monitor the placenta
- Confirm the baby’s position before delivery
These later scans are especially common for high-risk pregnancies or if the doctor has any concerns.
Why Timing Matters
Scheduling your anatomy scan at the right time is crucial. Too early, and the organs won’t be developed enough for clear images. Too late, and it may be harder to adjust the pregnancy plan if an issue is found. That’s why 18–22 weeks is considered the perfect window.
Key Takeaways
- First trimester: confirm pregnancy and due date.
- Second trimester: schedule your anatomy scan between 18–22 weeks.
- Third trimester: extra scans only if medically needed.
