I haven't personally seen Valerie Low at SGH, but I asked around my mum group and one of my friends said she had a good experience with a female gynae there and felt very comfortable throughout her appointments. If you are looking specifically for a female doctor, SGH does have a few good ones and it might be worth calling the clinic directly to ask about her availability and whether she takes subsidised or private patients. A few of us always recommend going with whoever you feel most at ease with, since that rapport really matters for gynae visits lah.
