How long were you ttc before clomid

Cassie
My husband and I have been ttc for almost a year and a half and last time I went to the doctor she told me I was still really young (24 at the time) and just basically to keep trying and try to be more active. I have pcos and I am overweight so her advice was valid and I have been trying ever since. I was thinking about going back to her in January but I am afraid I will just hear the same response, that I am still young (now 25). I was just wondering how long are couples typically ttc before they are prescribed clomid? I know each case is different but just trying to get a feel. Thanks in advance for any comments and baby dust to all!
