Everyone is different in what will or wont work for you, if you are not insulin resistant then metformin wont likely do anything for you since it is a diabetic drug given to type 2s to help them control glucose levels (some people do better on it in extended release form over the instant stuff).
I've never dun BCP never had a reason to start them, i was on depo provera for a few years but not for BC reasons and all i did was have the weight come off (over 130 pounds and have kept if off since long off of it in 08 and continuing to louse).
There are a number of things that impact PCOS when it comes to weight loss, what you eat can be one of them, plus stress and like all things how many calories you burn vs take in (its all like a fine line it doe seem/feel).
I've not been on anything hormonal myself since 08, though I do take a menopausal supplement from time to time, but thats about it. I just mostly watch what I eat trying to keep my glucose levels within range and keep as much soy content out of my system as I can (with soy being natural natural estrogen, i've found it does me no good and only causing problems/issues).
