How Should PCOS With Amenorrhea Be Treated For A Successful Pregnancy?

I have pcos, and have been on and off metformin for 2 years. all my doctor wants to do is keep putting me on metformin, now i have changed my doctor. ive read about clomid, how can i be put onto this? and how long does it take to fall pregnant on it?
i dont have monthly bleeds, although i did have one in january, started on Jan 21st for 5 days, but i havent had one since. me and my bf are sexually active as we want to get pregnant. i done a HPT in feb that said negative, and my doctor did a blood test and told me that "everythings fine and normal" but didnt say exactly what, and when i asked he just repeated "everythings fine and normal"

please adivse. :(
