how to get rid of bv/yeast infection?

first of all, im so sorry that this is super long, ive just been so worried about this and had no one to talk to or a way to get rid of it so i resorted to asking reddit.

this started the day i was leaving japan which was around may 7th. i noticed something was off with my discharge and i was super itchy down there. at first i thought it was just because of the pads i was using since i got them from a convenience store in japan but when i got home, the itchy was so irritating and my discharge was a grey color. i feel like it might have been the soap that i used to clean my v when i was there that may have caused this but im not completely sure. i usually use the dove unscented soap to clean it and i’ve never had any problems with it before. my symptoms towards the beginning was grey discharge, severe itching, and CONSTANT discharge. my underwear would be soaked because of the amount of discharge i would get and that’s not normal for me because while i do get a lot of discharge, i never have THAT much. i can’t remember if there was a smell or not. it’s currently june 1st and i think i still have BV or a yeast infection, though i can’t tell which one it is or if they’re essentially the same thing. my symptoms now are just still a lot of discharge but a yellow color with a kind of sour ish smell? it’s not fishy but it doesn’t smell right either. im 17 years old and i’ve never gotten this before. im also not sexually active/never had sex so it can’t be an sti nor fingered myself before this happened. i already talked to my mom and she said she would set up an appointment with my doctor but it’s already been almost a month since i’ve had it and im getting really worried and concerned. i also haven’t seen the doctor yet.

im seeing the guy im with in july (long time from now, i know😭) and i have a feeling sexual stuff might happen which is why i want to get rid of it. i know better than to have sex/do sexual stuff if i did have an infection or bv so is there any way to get rid of it asap (not for sex but for my sanity)?
