Yasmin Drospirenone, Managable, Whiteheads, Yaz, Cysts

I am in my second month of Yaz having switched from Yasmin -- Yasmin (or rather, the generic form) did not seem to have perfect results for my acne and after a year I decided to switch to Yaz because I thought that the longer amount of the drospirenone would help my skin.

Unfortunately, it seems as if my skin has gotten WORSE. I have no cysts on my face, but I have a lot of small whiteheads on my forehead and around my chin. And additionally, I seem to have little bumps on my chest and back -- places where I never had acne before. While my skin was not perfect with Yasmin, it was DEFINITELY clearer and more manageable, and this is just terrible.

I am worried that this is because Yaz has less estrogen than Yasmin. Is it the estrogen or the drospirenone that helps prevent acne? Is this just my skin reacting to the change in hormones? Should I stick with Yaz for a third month, or should I switch back to Yasmin at the end of this second month? How long should I wait before giving up?

I should also note that I started Epiduo gel about two and a half weeks ago, so I don't know if that would contribute to the fact that my acne has been getting worse, too.

HELP!
