I recently switched from Femcon to Yaz. Drospirenone allegedly is extra-beneficial for women with PCOS (though I had little improvement when I was on Yasmin, but that was among the first HBC I ever took, so it's been a while). Offhand, I know I've been on Ortho-Novum, Ortho Tri-Cyclen, Ortho-Cyclen, Yasmin, Estrostep, Ovcon 50 (holy God, never that much estrogen again for me, thank you), and Ovcon 35, which eventually became Femcon. I feel like I'm missing something in that list, but just to give you a general idea.
