pcos - next options

Hi all. My husband and I have been trying for a baby for 10 months now. The doctors have told me I have pcos but all my hormones are fine and my ovaries have no cysts. I am overweight and have lots of hair on my face chin etc. I have asked what now? and they have said to wait till January to be referred on the NHS. have long cycles roughly 45 days but I am ovulating. I take vitex but it doesn't seem to be doing much. I just wanted to know if metformin would be next option? I don't have IR according to the tests so not sure if it's suitable? any help would be appreciated.
