Eh boleh lah, 6 minggu dah boleh scan dan usually dah nampak heartbeat dia! Tapi aku suggest ko check dengan doc dulu, sebab some clinics prefer tunggu 8-12 minggu baru scan untuk tengok more details macam nuchal fold at all the measurements. A few of my mum friends, some did early scan at 6-7 weeks just untuk confirm baby is there and growing, so depends on your doc's preference juga lah.
