Baby head 99th percentile

Hi, I am a FTM, 30 weeks pregnant. Our baby boy has head circumference in 99th percentile, weight in 86th percentile, abdomen in 92nd percentile. His head has consistently measured around 95 percentile. Doctor brought up the topic of a planned c section. I am sad and nervous because I always wanted to have a natural delivery. C section recovery stories really scare me.

Just wanted to say this out loud and understand any positive delivery stories with large baby heads...

Edit: I do not have gestational diabetes and I have not gained a lot of weight (6 kgs/ 13 lbs so far). The doctor advised me to cut down on carbs and sugar to be safe
