Confused 🤷‍♀️

Went in for my normal check up I was 31.2 (according to glow and my due date) doctor says WOW he's really growing your measuring 35

I said wow that's a lot since in only 31.2

He said no 2 weeks isn't bad but since you have a history of GD we will monitor it. I said "um isn't that 4 weeks larger not 2? I'm 31.2"

He said no your 33 weeks

Me: isn't my due date November 18? Wouldn't that make me 31.2?

He goes and checks my dates on his computer and says yes my due date is November 18 but I'm 33 weeks based on ultrasound .....

Uhhh

I'm confused

Would make a little more since if he was going on the due date based on my LMP which would be nov 12

But saying I'm two weeks farther with November 18 due date has me lost....
