I keep having these recurring white, almost dead skin like discharge right after every period. I'm guessing this might be some yeast infection however there is no itching in or around my vagina or any swelling/pain. It's just a thick white residue that can I can feel and see on my finger is left in my vaginal canal. I was going to start on the betadine vaginal pessaries, is that okay or Is there any over the counter product that is helpful for it?
