Welcome to HCM.
Your ultrasound study report is perfectly normal.
There is nothing to worry. You have not mentioned the calculated gestational age
as per sonography
. If it is corresponding with your LMP gestational age then every thing is absolutely fine.
Banana and lemon sign are seen if there is some pathology in the brain of the child. Since they are negative, it means baby has no organic problem in the brain.
Wishing you a very healthy cute child with safe delivery.
