I got a yeast infection, how long will it last?!

when i get them they last anywhere from a week to two. try eating lots of yogurt that has acidophiles in it, that will eat it away, they have cream for it, but i never tried it so i don't know how good it works.

If you're SURE that it's a yeast infection, you should be able to go to any grocery store or pharmacy and buy some Monostat or any of the other creams to treat it. It should go away in a few days. The sooner you treat it the better.
