Aww, 22 minggu lagi best time nak monitor perkembangan baby! Generally around 400-500g je pada stage tu, tapi every baby is different jadi yang penting is your doctor sees consistent growth at each scan, a few of my mum friends got slightly different numbers dari their ultrasounds and doctor kata semua normal je. Best check dengan your gynae during your next appointment so dia boleh track baby's growth properly untuk you, okay?
