Ever Since I Had My Daughter 2 Years Ago (via

Ever since i had my daughter 2 years ago (via c-section) my vagina has felt loose and airy. It always has a strong metalic smell. I also always have a white mucus-like discharge. I've tried using yeast infection medicine and have even gotten some from a doctor but I'm afraid that I have some sort of constant incurable yeast infection. Plus, i have an extremely low libido. I also currently have the mirena iud. Do you have any idea what this could be?
