I’ve had two IUD’s put in, one in america that bothered me and ended up slipping out, and a different one here in China that is awesome. I’ve never had kids either. I love the IUD and would highly recommend it. Like I said, I don’t have a whole lot of info for you. I saw a doctor in the last city I lived in, in another province and she was a friend of my friend. The experience was great but that doesn’t help you in Chengdu. I know there is a women’s hospital though, you could probably google. I’ll ask my friend who used to live here if she knows anything.
