Thrush? (TMI)

I've had thrush in the past, but I'm not sure if that's what I have now. I don't get itchy around my vagina, and it doesn't sting when I pee or anything - I get really itchy up higher, at the top where the pubic hair meets the fold of skin iykwim - but it's only located there. Is it still thrush? I've had it for awhile, but as it's not too severe and it sort of comes and goes, I haven't been to see a doctor about it yet.

Also, I was wondering if this is the kind of thing I share with the midwives I see when I go for my antenatal appointments, or if I should book in with a GP?

I am joining this query because I have something very similar only its occurring directly at the opening of my vagina and nowhere else. No burning but its itchy on and off. (and I'm not pg btw).

If anyone can verify whether its thrush or not would be great. Am thinking its worth the natural yoghurt anyway, jic.
