Anyone else measuring ahead

Jaqueline
So I went in today to take my glucose test (which btw was disgusting I thought I was going to puke the whole hour lol) and my doctor measure my uterus. I've always been right on track but today he said I'm measuring 2 weeks ahead. I'm 27 weeks but measuring 29 weeks. Is anyone else measuring ahead and if so what exactly does it mean? My doctor told me not to worry and he'd check again in two weeks when I go for my next appointment. I've only gained 15 lbs so far so it's not that I'm overly 'fluffy' haha 😲 could it mean my due date will change??
