Best birth control options for pcos

I am waiting for ins. approval for RNY and my surgical team suggests that I go on bc now.  I don't even know where to start as I have never had regular cycles and was never able to get pregnant even with fertility meds.  So what's the best type of birth control pills for pcos?  OR should I try to go another route?  Not really too interested in an IUD.  What are my best options?  I am also not a spring chicken at 42 yo. 

Hey!
I am currently on the depo shot. As I do not want anymore kids, I double checked with my ob and she said since it is absorbed differently than the pill, my chances are greater at not getting pregnant. So if you're looking to not get pregnant, I would check more into the depo shot.

Thanks for the reply... somehow I missed it until today.  I had my b.c.consult yesterday.  My best options were the depo shot or the mirena.  So although I didn't think I wanted the mirena, it does seem to be my best option...so we scheduled it for the end of Sept.
