I think my due date was wrong

They changed it at my first scar from July 4 to June 22 due to measurements at the 8 week ultrasound. I had a growth scan this week at 36+5 and he measured at all points between 39 and 40+3. Has anyone else had a baby measuring this big??? I’m not diabetic, and they’re saying he’s 8lbs already 😱😱😱😱 they aren’t willing to induce earlier then 39 weeks either. I’m freaking out. I don’t want to deliver a 10lb baby!

UPDATE:

Baby Fitz born 6/4/18 (18 days early) at 7lb 10oz
