I Have A Thick Discharge, Kind Of Chunky And Off

I have a thick discharge, kind of chunky and off color...looks like oatmeal. It smells terrible. I went to a clinic and they treated me with Flagel I think its called. That did not work so they treated me for BV next then a yeast infection after all of the meds. I still have this awful smell and oatmeal discharge and now the smell is getting stronger. I know this smell is not right. I have not had sex in two years and been with the same man for 13 years.
