Anyone had their babys abdomen measuring bigger?

So today i went for a growth scan at 28 weeks and I could see her measuring things everything looked fine but the babys abdomen measured 30wks. I dont see my doctor until next week but of course by googling I got spooked lol.

I just did my GD test today as well so won’t get those results for a couple of days. I read it can be GD?

Anyone went through that?
