Baby is BIG. No GDM

Hi, i feel like my baby is getting too big (1kg @ 26 weeks measuring close to 28 weeks GA). Here’s the thing, I’m not a big fan of rice, have it many once in 4 days or so. My bread has always been wholemeal and I take my tea/coffee without sugar (since uni days) but my baby keep growing bigger and doc keeps advising me to control my carbs/sugar intake. I seriously feel like I’m not taking carbs and sugar like average people since i dont like them. Tested for GDM and my glucose level was normal, borderline low.
