Yeast/bv causing me not to get pregnant

Help like I’m seriously about to lose it . I can not shake these Bv/yeast infection i am so tired of diflucan im tired of getting screened and it’s just yeast . Currently TTC... i take medicine clears up for a day or two then it’s back . I am beyond frustrated and I’m tired of these doctors telling me the same thing and i get the same results . Anybody know anything about chronic/reoccurring yeast infection . I think this is why I have no luck conceiving. Any natural remedies ?
