PCOS: Metformin & Clomid

I was diagosed with PCOS about 7 months ago. My doctor informed me that the best chances for me to conceive would be to stay on birth control until I was ready, and when I was ready to come back and he would put me on Metformin and Clomid. We are going in on Monday to start the process. 
I would love to hear your experiences being on Metformin and Clomid and what to expect. Or anything about your experience with PCOS!! Thank you.
