My naturopath suggests organic yogurt.... not to eat though

If you buy a tub of the organic yogurt, and wipe it around the outside of your vagina (basically the same as you would apply the canestan).

You'll need to wear liners/pad as its messy and feels a little ew... but it apparently works

I haven't had to do it myself, but I did ask her once on behalf of my cousin who suffers really badly during pregnancy.
My cousin said it worked fantastically for relief

Good luck hun
