help please

so i feel like i always have something wrong down there. i’ve noticed after sex i smell some what fishy/off down there. i have like white creamy discharge then the smell. sometimes it itches just a little nothing crazy. i started taking probiotics. idk what to do to get rid of the smell and discharge. i’ve been a lot drier down there like with sex and every day. i got tested for stds recently and i was fine. what should i do? i’m tired of going to the doctor for this sfuff

all the time so if anyone has some tips or advice that would be helpful
