Getting tested for pcos??

I’m trying to get a doctors appointment to discuss possibly having pcos and I just wondered what would happen at the appointment? Like what sort of questions should I ask? What type of questions will the doctor ask? What kind of tests do they do? I’m fairly certain I may have it as I’ve been ttc for about 15 months now and according to ovulation tests and bbt it looks like I may not be ovulating every month and my periods are really irregular I’m on cycle day 57 now. Can they give me clomid if I don’t ovulate every month? Sorry for so many questions but I’d like to be prepared
