What are the best ways to truly prevent uti during pregnancy? thanks.

Hydrate, Probiotics: Staying well hydrated is a simple way to decrease the frequency of urinary infections. A probiotic supplement, supplying "healthy" bacteria, may help restore balance to the bacterial population in the intestine, and has the added benefit of reducing yeast infections. Yogurt is a good example of a probiotic, also supplying a calcium source. Cranberry tablets have protective benefits, too.
