Hi, I am 30 + 1 weeks today as per scans, and as per due date 30+6 weeks. I have had my growth scan today and found out that my baby boy's head circumference is measuring at 90th centile and the posterior ventricles are 10.1 mm and 9.6 mm. Everything was normal in my 19+4 week scan, where the ventricle was 7.7 mm. I am scared now. Will the measurements (specially that of the ventricle) go down? or can it increase more?
