Baby measured BIG 😳

So I am supposed to be 37w5d (due Sept 30), and at my high risk doctor the other day a sonogram showed that baby was measuring a couple weeks ahead at an estimated 9lbs 4oz, which would be typical for around 40w3d. I am going to see my regular doctor today for the weekly check (he will do the stress test and check me for dilation).. I am just wondering what other Moms who have measured big have been told?

I know people have 9lb babies, it’s just that my first was born at 35 week and was 5lbs, so 9lbs sounds very big to me. 😬😳😂
