Odd smell?????

So I went to the doctor with concern of infection in my happy place, but he said that there were no signs. I don't have any itching, or weird discharge. I shower regularly, but it seems like no matter what I do, I can't ever smell fresh and good down there. I don't have the best diet in the world and I have PCOS. Am I crazy? Anybody else have this problem? What could this be? Thank you for your help ladies!!
