Okay So I A Few Months Ago I Got A

okay so i a few months ago i got a bladder infection, then i got vaginl intching and my docotr figured i got a yeast infection never gave an exam even though i had never had one and sent me on my way telling me to get monistat. The otc creams burned me pretty badly and by the time i got to plan parenthood and got swabbed they said i had nothing, and by that time the itching had went away.
now, again i had he same feeling of the itching, i didnt have a particularly different odor and a pharmasicit told me to use a different cream for a yeast infection with an active ingredient that started with a c. today was the fist day i havent used it and NOW the discharged is white, kinda whiteish with spots of brown (i did just finsh my period about a week ago) and the itching is back. any adivce until i can get an appointment. my mom thinks trich i think BV but nothing seems to help, i am clueless
