How can I treat pcos naturally?

I've tried birth control and metaformin I wanna try to do herbal stuff, vitamins, basically, healthy stuff I no longer want to take metaformin because I don't want to damage my kidneys and I want to avoid birth control because of the weight I pick up fast from them especially when I'm supposed to lose weight and not put on........Plus I've spoken with my doctor before and I've told him my concerns with the medicine's (and with the metaformin I would have to take for life is what I was told) and he said that it was best for me to just eat healthy and just exercise to lose weight and balance my hormones because both pills are not good for me in the long run.......has anyone have some advice and tips on how to go natural with pcos?
