How to deal with numerous - HPT?

I have been trying to conceive baby number one since we got married in September 2007. I just started a gluten free diet due to my body not handling wheat well, on 4/21/11. I cycled 4/9/11 - 4/16/11 and had light bleeding and lots of CM from 4/29 - 5/3. I took a test on Monday 5/16/11 the day my period was due, and got a NOT PREGNANT! I still haven't had AF yet, but have been having cramping, sore , and backache... since my fertile time. I was hoping to get a BFP pregnancy test, but I guess it's not time. Anyone else out there have this issue? I have pcos, and have lost 65 pounds... any ideas on how to handle the downs of the pcos and ttcing? thanks
