Baby’s head measure

Hello, today I got the results for my 32w ultrasound, I got it done because they diagnosed me with GD, all my sugar levels have been ok, only few here and there a little high but nothing to be concerned about, but with the scan, the Dr told me that my baby’s head is measuring big 😥, most my family from my dad’s side have big heads, but should I be concerned about it? Has anyone had this results and their baby came out with normal size? And were you able to deliver natural or needed C-section? Isn’t a lot to measure 3w ahead only his head?
