literally about to cut my vag off

so the past year almost, i’ve had this type of discharge that builds up throughout the day and sits on literally my whole outside vagina and it gets itchy if i don’t wash it out after a while of it sitting. it doesn’t have a smell but if i like go down to itch anything, i bring my finger back up and it looks almost chunky, not the consistency of cottage cheese, but it looks like the thickness of it was just rolled off onto my finger. i’m literally so tired of it. i take cranberry extracts daily, women’s probiotics, drink plenty of water to keep stuff flushed out, don’t wash with soaps, etc. i don’t know what it is and i’m getting to a loss.

little backstory:

i’m 16 and have been on nexplanon since december 2018 so i don’t know if that could have anything to do with it. my boyfriend used to finish in me almost every time but i started getting yeast infections from it so he pulls out almost 95% of the time now so that’s how i know it’s not that either. if this sounds familiar to anyone or if anybody has dealt with it before please share your advice!!
