Is this normal or has this happened to anyone 😭

I’m 29 weeks pregnant and I had my second growth scan baby is measuring 2 weeks ahead still & is already 3 pounces 10 ounces his head is in the 99th percentile, I really want a natural child birth & my doctor was telling me if he reaches 9 pounds and keeps growing at this rate we’re going to have to have a c section 😔 has this happened to anyone or has anyone been told they might need a c section but everything turn out normal in the end and you didn’t have to end up having one ?
