Can self-diagnosis deter doctor from helping me?

When I suggested to my doctor that I have PCOS (Poly-Cystic Ovary Syndrome), explaining to her my symptoms; which are hallmarks of this condition. She concluded that the symptoms i'm experiencing dosen't sound like PCOS. I also stated that my Mom has PCOS and still she did not believe me. I'm having acute hair loss( lost about 3/4ths of my hair); bodily hair growth (legs,arms groin,navel,auxillary,etc);heavy menses; skin discoloration, etc. So any advice on how to proceed with this doctor or if I should change doc is well appreciated.
