Perinatologist appointment

I’m 34 weeks pregnant now and had a growth scan at 32weeks. My baby was breech ( doctor not concern about it yet) but my baby belly was measuring 3 weeks ahead of his head and c-section was mentioned due to him being big. I want natural vaginal delivery. I have appointment with perinatologist by the end of the month for another growth scan. Anyone was maybe in the same situation?

I also wanted to mention that on my 32 week scan lady was hurrying and I am thinking now if she could’ve not measured the baby carefully.
