I've never been on Yasmin, Yaz, the Nuvaring, or Mircette. I can tell you, though, that where the pill is concerned, most likely the reason for your mood issues with it is the fact that birth control pills deplete many of the B vitamins, which are important for the mood. Taking a B complex vitamin every day with your pill might help you feel better emotionally. It worked very well for me when I had depression from the pill. I don't know if it would work with the Nuvaring or not, but I think it's worth a try. Good luck. :)
