First of all you always check with a Pharmacist first. Its true that certain antibiotics can give you a yeast infection due to the fact they tend to "kill off" the flora in that part of your body. Also be aware that certain and most can also make birth control pills non effective for 30 days so use another form of protectection until your next full cycle.
Conventional doctors will not listen to you about this, unless the fungus is enough to make you sick enough to be in a hospital bed. I suggest seeing a naturopath and get on a Candidas diet. You will have to radically change your diet, but it is worth it. The Candidas diet should help prevent diabetes, too.
