I think your doctor will probably tell you which brand of treatment is best. Yeast infections are a pain, even when not pregnant.
As a preventative, eating yogurt is great. You need to make sure that you buy a kind that has active yogurt cultures. Most of them do but some of the more processed kinds ( with all the fun things like candy and the like added to them) have a lower count of these cultures. I try to buy plain and I add a ton of fruit to it. It also has the added benefit of being a great source of calcium and low fat or fat free if you buy the right kind.
