BV or Yeast infection?

Ivy
Can anyone please tell me the difference of symptoms between the two (BV AND yeast infection) !. I am currently experiencing a very itchy and sorta burning vagina, swollen and sometimes I get this white discharge that is chunky like cheese like queso fresco or ricotta. If this is a yeast infection please refer me to some over the counter medicine and how to prevent this from happening. There are so many that idk which to choose 😔
I am clean, always change underwear everyday, shower every night and only clean my cookie with warm water no douching.
