32 week scan size??

So I had my 32 week growth scan yesterday and it says baby is measuring 4 lbs 13 oz which is the 78% percentile (and yes I understand it’s plus or minus one pound) but holy big baby. Has anyone had their babe measure that big at 32 weeks and not have a monster 8-10 pounder? I’m getting a little nervous for birth now and my biggest fear is a c section. I really want to do this natural (and it’s my first) so I’m a little worried now. Also my belly is measuring exact every time so my dr is not concerned at all about size, but she also doesn’t have to push him out... lol
