97th Percentile at 30 weeks

SN
I had to have a 30 week ultrasound today due to high hormone levels and the risk that my baby would be small. Well, my guy is measuring in the 97th percentile weighing in at 4lbs 8oz. Now we go back at 36 weeks this time to see if he's too big and if I need a c-section! What a crazy rollercoaster!
Has anyone measured similarly and what was your outcome/ how are you doing?
