Aww don't worry, 3.2kg at 37 weeks is actually normal-normal je, not considered big! A few of my mum friends dengan GDM on diet control pun deliver around their due date or even slightly early, jadi macam-macam je lah, every baby different. The best thing is to have a proper chat with your OB about your baby's growth trajectory and their plan lah, sebab they'll look at your scan, blood sugar control, and baby's development, bukan just the weight number aje. Hopefully everything goes smoothly for you!
