Alah ada lah sis, at 16 weeks scan dia akan show baby's limbs, heart, spine, semua organs, tapi still quite small in the image so tidak as detailed as the 20-week scan. Masa aku 16 weeks dulu, sonographer tengok basic development je and confirm heartbeat, tapi the 20-week scan is the one yang laaaaagi detailed where they can see almost everything with clarity lah!
