Dirt in my vagina???

I swear I’m not dirty at all, and I bathe every day, also I havnt had sex in 10 months, but for some reason I seem to have dirt in my vagina?!! I always rinse my vagina but today when I wiped myself there was dirt on the tissue and I rinsed myself with a cup and a lot dirt fell into the tub! Now I knoe its not period blood because I’m having 0 pms symptoms and when I get my period my pms is on 100000. What’s going on?
