Babies belly measuring bigger?

I had a growth ultrasound today (I've had them monthly due to hypertension) and overall she's in the 62nd percent which is great but they said her belly is measuring in the 90s and asked me a couple times about my GD testing. She's at 3.3 lbs also . I actually took that test twice and passed with flying colors both times. My ob appointment is tomorrow but in the meantime any other mamas have this happen? Any idea if there's a reason or if it just evens out? I got lucky with a couple 3D pics too 😍
