I can't really think of much to ask, as I'd also suspected PCOS and had researched into the area before my diagnosis, and researched a lot more thoroughly after my ultrasound revealed PCO, so I knew a lot about it before I saw my GP again.

Basically, you are going to want in internal US to check your ovaries, and you are going to want blood tests to check hormone levels. It may be an idea to get other tests done (such as thyroid) so that you don't end up missing anything by skipping to the obvious - this is what I'm starting to suspect may have happened with me.

If they do diagnose PCOS, make sure you ask about metformin and other treatments.

You may find that a GP is reluctant to actually do too much themselves (and they mostly don't appear to know about metformin as a PCOS treatment yet) and will mostly want to just refer you to a specialist. In that case, insist on the internal US and blood tests first so you can take them with you to the specialist and get the ball rolling from there rather than having to wait for other tests first.
