Scheduled c-section due to big baby

Have any of y'all had to have a scheduled c-section due to baby being on the bigger side? How do doctors make the decision on how big is too big for mom? We are 34 weeks and baby is measuring kinda big but not too big. I see my OB in a few days and I want to ask her. I'm just scared I won't be able to push out a baby let alone deliver a 9+ pound baby!

Edit: biggest reason for this thought is at 32+3 we had a growth scan and baby was measuring almost 6 pounds. Her head alone was measuring at 35+6! Daddy has a fat head so I'm concerned.
