Sayang, I know this is scary for first-timers! Tapi honestly, size kantung yang kecil dari expected dates tu quite common, a few of my mum friends went through this and everything turned out fine. Jangan risau dulu, tapi kena follow up closely dengan ob kamu. Sebab tu dia suruh datang scan lagi bulan depan, to track growth properly. Kita tak boleh predict outcome based on one scan je, kena tengok trend growth masa follow-up. Trust your ob's plan, and try to relax dalam few weeks ni while you wait. Lepas scan yang next one, baru ada clearer picture. Sending you lots of baby dust!
