Aiyoh jangan stress sangat lah, a few of my mum friends also kena sama situation and semua okay je! Two weeks behind is actually normal range, doctor boleh monitor closely ja and usually babies catch up after birth especially if measurements lain okay. Since head, bones, dan weight semua normal, it's just the body size slightly smaller which is truly not a big deal, banyak healthy babies born yang kecil sikit. Just make sure you're eating well, drink plenty of water, and go for your regular scans so doc can keep an eye, then relax okay? Most of the time these babies do just fine!
