Hi Julie
I don't think GP's here will have an attitude towards any woman who wants to go on the pill. The pill although mainly used for contraception is used by alot of women for other reasons such as regulating periods and regulating the flow.
There are expat doctors here both male and female that you could go and see but after living here for 10 years and having had both Expat and Singaporean doctors, I am happy with the standard of care offered by both.
Good Luck
