Alhamdulillah, congrats on your pregnancy! Macam-macam factor ada yang influence baby size, genes, nutrition, mama's health, so memang boleh ada babies yang besar, tapi hard to predict exactly berapa kg nanti la. Since doctor dah monitor and your glucose test okay, best thing is just keep doing what you're doing, maintain healthy diet and check-ups regularly, then let the doctor track growth at each scan. A few of my mum friends had bigger babies and alhamdulillah semua deliver okay, tapi memang doctor akan adjust plan dekat akhir trimester kalau needed. So far so good on your end!
