Vagina discharge

Hi beautiful people

So for the longest months I’ve been struggling with discharge I’ve tried yeast infection cream it clears it up than i get it back

I’ve tried douche it also help for a few days

I’ve been to my doctor and she send me to the lab to get tested for hiv/aids std and more ( basically i did blood test and vagina pop test or how ever you call it)

I know this is long but I’m tired my test game out good so I don’t have those

my doctor can not give me an answer to what i have

Right after my period i got like a watery discharge and it itches really bad down there
