Pk women (Dr tan poh kok)

I haven't heard of Dr Tan Poh Kok at Potong Pasir myself, but a friend did mention going to a women's clinic in that area and she was quite satisfied with the doctor's approach and the cleanliness of the place. Since there aren't many reviews floating around online, maybe try calling them first to ask about their services and fees, or check if they're registered with MOH so you know they're legit.
