Your GP can definitely refer you for a scan for PCOS if you ask - cost me around $250, but could claim most on insurance. I'm pretty sure in NZ you need to have a high follicle count to get an 'official' pcos diagnosis, though I do know that AMH levels via blood tests can be used as well overseas.
If you did see a specialist, it's around $250 for the first appointment (depending on where you go), which includes an internal scan to check for any visible issues. I also know that they would almost definitely give you clomid to make you ovulate, and take it from there. While you can have a period without ovulating, you can't ovulate and not get a period (unless you get pregnant that cycle), so the fact you haven't had a cycle since April means you're not currently ovulating. It might be your cycle is still stuffed up from the pill (can take a full year to come right), and will sort itself out with a bit more time, or you might need drugs! Apart from clomid, the other thing that can help is metformin (which your GP can prescribe, especially if you emphasise weight-loss, acne, etc) - metformin is a insulin-sensitizing drug that is good for people with pcos in addition to diabetics.
Hope this helps at all!
