Repeating an anomaly scan just a few days apart is safe for your baby. Ultrasound works using sound waves, not radiation, so there's no added risk from doing it again so soon.
Next Steps
The missed views were most likely due to the baby's position that day, not a problem with your pregnancy. Carry your first report to the new radiologist so they know exactly which views to focus on.
Health Tips
If the second scan also misses those views, please see your obstetrician to discuss timing. Waiting until 22 to 24 weeks often gives a clearer picture.
