I Had A Complete Hysterectomy About 5 Years Ago. Over

I had a complete hysterectomy about 5 years ago. Over the past several weeks I have had a lot of vaginal discharge; becoming increasingly foul smelling. I have been wearing adult diapers, because it is so extreme. I will be making an appt with a gyn, but just want some information before. I will be with a new dr and want to be prepared with the right questions.
