I had a colposcopy and the doct used vinegar and iodine solutions. i have a brown coagulated tissue-like discharge. normal? how long should this last?

Normal: It was vineger and iodine to make the lesions show up better, then after the put an orange-colored rusty substance to help stop bleeding. You can gently rinse it out in the shower with a finger and water and then you won't have a week or more of random orange-staining goo coming out. Good look, and ALWAYS were condoms so you won't have to go through this again.
