Need advice !!

Kallie
I was diagnosed with PCOS when I was 16 I am now 25. It feels like it is getting worse every year and I am scared that my window is closing sooner than I want. My fiance and I have been trying for the past two 1/2 years and nothing has happened. We have tried ovulation kits and I have even been on the fertility cycles from the doctor. Nothing yet :(. Ladies with PCOS what are some tips and advice that could possible help us conceive or help me get through this without stressing beyond belief??
