Alright so on Monday I came down with a pretty serious yeast beast. I'm 100% positive it is a yeast infection. I'm prone to them so I've had a ton. Last month I had one an used my cup for the first day of my period after which I just let things flow and the infection cured itself. This month I forgot to boil the hell out of my cup and reinfected myself. This is day 3 of my boric acid treatments (not the first time treating with boric acid) but the outside of my vag is still VERY red, swollen, burny and itchy. Is this an external yeast infection? I'm not sure what to do. Please help!
