Yeast infections

I suffer from yeast infections for as long as I can remember. I've taken diflucan, otc stuff and they will go away but ALWAYS come right back. I tend to go to the doctor to get tested a lot for it just so I'm aware when I have one and When I go to the doctor they test me and they always say I have a yeast infection but I'm always suprised because whenever I have one I don't have any itching. My symptoms are usually just discharge. Does anyone else get yeast infections a lot? And what has worked for you? I've been taking probiotics and I know that can take a while to kick in. What has worked for you? I would like to know. Just so tired of dealing with them and I also notice that whenever I have a yeast infection I'm always dry down there so I think that has a role in it too. And I've been tested for diabetes, stds, everything else so I know it's not anything else so no comments of that kind.  Thank youu :)
