8 Weeks Pregnant: See Your Baby Move on Ultrasound
At 8 weeks pregnant, your baby is growing fast. One exciting thing you can see now through an ultrasound scan is your baby starting to move. It's a special moment that shows your baby is active and healthy.
Heartbeat at 140–170 BPM
By this week, your baby's heartbeat speeds up to 140–170 beats per minute. That fast heartbeat is a good sign that your baby is growing well.
How Big Is the Baby?
Your baby is now about the size of a raspberry. Even though still tiny, your baby is already forming organs, muscles, and nerves — the basics for a healthy body.
Baby's First Movements on 4D Ultrasound
You might see small movements during your ultrasound scan. Using 4D technology, you can watch your baby move for the first time. You won't feel anything yet — that usually starts around the second trimester — but seeing movement is a great sign your baby is active.
What Are the Black Spots in the Brain?
During the scan, you may notice black areas in your baby's head. These aren't dangerous. They show where the brain is developing — including the forebrain, midbrain, and hindbrain — which are all part of the nervous system.
Why This Scan Matters
The 8-week ultrasound scan helps confirm your baby's heartbeat, size, movement, and brain development. It gives you peace of mind and allows your doctor to check that everything is going well.
It's important to choose a scan center that offers clear images and explains things properly. SonoCare Ultrasound Scan Centre provides detailed early pregnancy scans with care and support.
What's Next
After 8 weeks, your baby will keep growing fast. Organs and systems will develop further, and in the coming weeks, you'll begin to feel those little movements. Regular scans help track progress and catch any problems early.
