New to the board, hello

Warning: this might get a bit long. I've now been off the pill (I was previously prescribed Diane 35 and took it for about 5 years) for about three months. I was taken off the pill because I had high blood pressure readings in the last two or so months I was on it. Diane worked brilliantly for me - I had regular periods, I've lost about 13 kg and had great skin, even my neck discolouration went away.
Now that I'm off the pill I'm still getting the regular periods 3 months on which is good, but I've noticed that my skin's gotten a lot worse and I'm steadily gaining weight. I absolutely hate it and I want to get back on the pill, but my GP is erring on the side of caution and wants me to be completely off it. I was referred to an endocrinologist to chat about my options, but she basically spent that time dismissing my concerns - she didn't believe I have PCOS because I don't "look" like I have PCOS. Duh, I've worked really hard to look like I do now??? The original doctor who diagnosed me with PCOS 5 years ago didn't check for cysts but saw that my hormone levels are whacked and said that I don't need to have cysts to have PCOS symptoms. The endo on the other hand thinks that you need to have cysts to have PCOS and thought that the diagnosis was made in error.
I'm due for a follow up with the endo in February next year and I plan to talk to her about oral contraceptive options but I want to go in there with as much info as I can about any possible options so I don't leave without knowing that I've asked her everything I need to know.
So! After that mini novel (thank you if you got to this point btw

) - what are my non-barrier contraceptive options? I'm basically looking for something that helps the PCOS, doesn't affect blood pressure and ideally won't make me gain heaps of weight. Nice skin is also a bonus. Does such a thing exist or am I just dreaming? Someone else recommended the Mirena IUD but I don't think they'll give it to me since I haven't had kids (I'm in Australia). Also the pain factor of IUD insertion scares me a bit. Thanks for any insight!
