Aih mama, 3rd pregnancy memang lain sikit kan, I can feel how anxious you are especially dengan GDM yang baru kali ni kena! The good news is you're almost at the finish line (3 days away!), and your doc is on top of things dengan metformin na. Just one thing though, that sudden 15kg weight loss + not feeling hungry + frequent nosebleeds yang heavy tu sebaiknya you mention again to your doctor or even just call the clinic, sebab tu combination yang tak typical even for GDM, and better safe than sorry when you're this close to labour. You're doing great, mama, doakan semuanya smooth for you soon!
