Hey ladies, 21+5 weeks now. In my 21 week anatomy scan, Radiologist said my baby's bpd is in the 3rd percentile and head circumference is in the 5th percentile. Which she said may be genetics to have a small head. No abnormality is seen otherwise. And also I have bilateral grade 2 uterine artery notch. When consulted with my obstetrician, he advised a follow up scan after 3 weeks and could only discuss comparing both the reports. This is my rainbow baby I'm worried. Any advice or suggestions are welcome.
