Do you know about pro-biotics? Acidophulus bifodus can be bought from health food shops and will help restore the balance of mircroflora.
Candidas feeds on sugary, yeasty foods so cut right back on them for a bit.
I had terrible thrush in pg, cream didn't clear it. MW suggested I thread cotton through a garlic clove, put a couple of drops of tea tree on clove, and put it inside vagina (leaving a cotton tail haging out for easy retrieval).
Sounds radical, but it cleared overnight. What a relief it was.
Good luck.
