Since your previous gynae has left NUH, it might be worth calling the NUH Women's Centre directly to ask which doctors are currently available and taking new patients, as the lineup does change. Going private at NUH still gives you the hospital's facilities which you are already familiar with, though some mums do explore Mount Elizabeth or Gleneagles if they want more options to compare. I would suggest asking around in your antenatal class or even the NUH Facebook page, as other mums there often share recent first-hand recommendations. Congrats on your 3rd pregnancy, hope you find someone you are comfortable with soon lah.
