Measuring BIG!

FTM here, so I had an appointment today, I’m 33+2 but measuring 38. I know fundal height can be way off but I have consistently been measuring big and it seems to be getting bigger each time. My midwife wants me to do two separate growth scans to see how big/fast he’s growing. Just wondering if any other mamas have experienced this with their pregnancy’s and how it turned out! I don’t have GD and have only gained about 8 lbs so far so it seems crazy to think he would be so big!!
