Is this normal?!?! Thoughts please!!!

FTM here. I’m 27w 2d & my baby is measuring 29w 3d, & approximately 2 pounds 9 ounces and he’s in the 93rd percentile, but they are not changing my due date apparently. Could my baby come sooner at this rate? Is there a reason my due date is still the same even though he’s big? Maybe he’s just growing fast. Thoughts?
