I'm experiencing only my second bout of thrush. The first was last year after some major antibiotics which I know is very common. However this time it's come from nowhere so I'm wondering if it's something I've done? I assumed I wasn't particularly prone to getting it so don't know what has changed. I am well aware the vagina is self cleaning and doesn't need to actually be washed but could it be z hygiene thing? Or any other suggestions? It's so expensive to treat I'd like to minimise occurrences if I can!
