Measuring ahead....

Audrian
So at 20 weeks my baby was measuring 2 weeks ahead. My doctor did an early glucose test and it came back normal and negative for GD. He is going to have me retest my glucose at 28 weeks to be safe. He said since I have already had an average sized baby that's it's unusual to have a big baby. He guesstimates this baby will be 9+ pounds. Has anyone had this before?
