Some Kind of Vaginal/Urinary Infection

First of all, I’m so sorry to be that poster that asks for medical advice about stupid things. This has me freaking out a little though. Yesterday, it started hurting a little when I peed. It has progressively gotten worse over yesterday and today until I can hardly walk for the pain and it has spread to my vagina. I just took a shower and checked “everything” out and I got what looks and feels like a little piece of skin (pictured) off of a q-tip I was using to clean off

pus. It’s all raw and bleeding when I clean it. My husband and I are both exclusive and have been tested. Is this just a yeast infection or something else in your opinions?
