I think I have a yeast infection.

yesterday I was in the bathroom, and.......
nasty white discharge... and it smells BAD!!!!
that's a yeast infecion... right?
I didn't really think to post about it yesterday,
because I really didn't think much of it, because
I guess I kinda thought it wasn't one, because
it didn't itch, and don't yeast infections itch?
Well...... guess what? today it is starting to itch.
