Wa'alaikum assalam sayang! Polyhydramnios (air ketuban berlebih) boleh ada banyak sebab, sometimes it's just how baby's developing, sometimes ada mild issues yang doktor kena monitor je. Since you've confirmed no GDM and pakar dah arrange follow-up, that's the right move, pakar akan tengok pattern and track everything untuk safety baby and you. I had one mum friend dekat pakar dengan situation similar, and just regular scans helped doktor understand apa happening. The good news is you're already under supervision, so rest assured you're doing exactly what you should! Jangan stress sangat ye, follow-up appointments tu untuk peace of mind both sides. Any questions or if you notice anything different (like sudden shortness of breath, belly pain), mention to your pakar right away, okay? You're doing great, mama!
