I used to go to Thomson TCM before I was pregnant. I think they do see pregnant ladies there, but mostly to help stabilise the pregnancy and relieve the symptoms in the first trimester. The physician I saw has left, so I can't recommend a specific physician. But I think most of their physicians specialize in gynaecology. https://www.thomsontcm.sg/physicians/ If not, I heard that some of the physicians at Eu Yan Sang paragon clinic also specialize in gynaecology. But I did not try them.
