Growth Scan: I had a growth scan ultrasound where everything appeared normal but my little one's AC measured for 28 weeks i.e; smaller than the size his abdomen should be at this stage. She will be conducting dopplers(which I am completely unaware of) next week. But, this had me worried like crazy as she said that we might have to deliver the baby early if the doppler shows risks of low blood flow or any other issues. Please tell me if I should be worried sick or what should I do to improve the baby's SC before that scan ?
