Aish, 34 weeks memang tough period lah, a few of my mum friends had the same gejala around that time, macam preeclampsia symptoms or just the weight of baby pressing everything jadi semua rasa uncomfortable and nauseous. Sakit kepala + loya + perut sebu tu memang perlu check dengan doctor jangan tunda, especially at this stage kena pastikan blood pressure okay and semua normal je. Drink plenty of water, rest as much as you can, tapi honestly best go get yourself checked out, better safe than sorry when you're this far along!
