BornConfuzed, I understand how it is. I personally was put on bcps which weren't any help when it came to weight loss. And now I switched to Actos and my weight is coming down slowly but surely.
I wouldn't beat up myself about it, you found what works for you so make the best of it and make up for those lost/regained pounds by focusing on what works and doing your best not to go back.
You've lost 20 lbs in 9 weeks, that's amazing for someone with PCOS!! Imagine if you started doing some activity

PCOS can be frustrating, and what works for me may not work for you or the next PCOSer. But we're all here together experimenting, learning, sharing and supporting each other. It may not be curable but it is treatable, it will take us longer but we'll get there
