I Am A 31 Year Old Female. I Have Pcos.

I am a 31 year old female. I have pcos. I am ttc but no luck. Have taken one round of clomid but doctor said it didn't work. He put me on progesterone for 10 days and I haven't started my period yet. I can't start the second round of clomid til I start. Now when I pee there is a light pink on the paper, but my pee is not discolored. The pink was not there before I pee, soi don't think it's my period. I burn some when I pee as well. What could this be? Should I be concerned?
