HELPPPP

Okay so a few weeks ago I went to the doctor and they claimed I had a bladder infection. I didn't have any symptoms nothing that even made me think I had one, but I still took the medicine. On Saturday, I started to get symptoms, weird discharge, burning urination, a handful of other symptoms as well. Now I know I shouldn't have done this but a friend of mine had the same bladder infection medicine that she wasn't using so she gave it to me to take. Before I started taking the medicine I noticed I had a cut on the inside of my labia minora. Over the past couple days I've noticed more cuts and white bumps. They don't itch or anything, they are just very irritated and hurt when pee or are constructed by my underwear.
