New pill for my PCOS

So I have pcos and I've tried about 5 different pills in the past year and none of them have suited me, they've all given me super bad pains, and either made me clot badly or barely bleed at all.
Now being off of the pill for about 2 months- heavy, painful and irregular periods. I'm now being put onto the pill Dianette- I think it's called. 
But my doctor is a little wary because of my weight- however she will be monitoring me on it. But does anyone have any experience of that pill? 
Also, I am extremely flat chested and due to my size it makes me really insecure as they do not suit my body with them being so small, and I think that is partially down to the pcos and the imbalance of hormones making my breasts not develop properly. Therefore, I was wondering if this pill might stimulate their growth?
