Boleh je scan lagi kalau nak tenang hati, especially yang first baby macam you! A few of my mum friends did extra scans near the end just to check baby's position and amniotic fluid level, terutama kalau takda tanda² bersalin lagi. Private clinics usually boleh arrange on short notice. Tapi sebaiknya check with your KK doctor dulu, sebab dia ada your full medical history, sometimes depa pun boleh arrange scan cepat kalau ada concerns, atau even refer you to check at hospital instead. Good luck with your delivery soon!
