Vaginal Odor

I am in the process of transitioning to a raw vegan diet - two weeks now. All of a sudden during the last week I have this awful vaginal odor with no discharge. How can I get rid of it and is it diet related? Just curious. If I go do my physician I am sure he will prescribe Antibiotics and I don't know if that is the correct course. There is no discomfort whatsoever. I do have lichen sclerosis but that has been under control for several years now.
