Your Pregnancy Journey in 3D Ultrasound: What’s Happening at 6 Weeks?

At 6 weeks pregnant, your baby is growing rapidly, and exciting milestones are happening!

✨ 3D Ultrasound at 6 Weeks

• A gestational sac, yolk sac, and tiny fetal pole may be visible on 2D and 3D ultrasound depending on the ultrasound equipment and the practitioner.

• A heartbeat may be detected, though in some cases, it may still be too early.

• Visualizing and documenting an intrauterine gestational sac, yolk sac and an embryo with a normal heart rate (120 bpm) would be considered a viable pregnancy.
