I always get a yeast infection during the week before my period. I've been to the doctor the multiple times and there isn't anything wrong that they can pinpoint. I've always been told by the doctors that some people are just prone. My mother has the exact same problem. Always in the week before our period to varying degrees of severity. Sometimes I need to treat it, other times I can wait it out and if I can make it to my period my body will usually correct itself. Does anyone else experience these types of problems?
