Aww sayang, jangan risau sangat okay, a few of my mum friends ada baby yang measured small on scan jugak, and baby diaorang lahir perfectly fine at normal weight! Doc ko betul, at 22-24 weeks the difference mmg tak besar sangat, and yang paling important is baby ko active, heart beating strong, and air ketuban normal, tu semua good signs Pergi je to the government clinic untuk confirm scan, they'll monitor ko closely, but honestly baby yang kick-kick aktif macam tu usually doing just fine. Firstborn anxiety is real, but try to trust your body and your baby's signals, you're doing great, mama!
