My second son was measuring large too through out pregrancy he was in the 97 th percentile and even at 3 weeks when we did his week check up he was measuring at 55cm and 7 lbs 10 oz so our Dr was like he will be a tall boy
“Measuring large for gestational age means your fundal height is more than 3 centimeters larger than expected for your stage of pregnancy, based on your due date. Your provider will probably schedule an ultrasound to find out why. You could be measuring large for gestational age if: Your due date is off.”
