Still itchy?

So I been having some itching down there. I went to the gyno to get it checked out so I got an std test and she told me I have Bv which I get kinda often and so I got the antibiotic cream you put up your vagina and a pill for yeast infection. I used both as instructed & my std test was negative. But I’m STILLLL itchy. Idk what do do??
