During my last 2 periods I've ended up very itchy and burning down below and when I had a look, it looked quite red and sore. No discharge or smell at all but last time it happened I assumed thrush, dosed myself with a Canestan capsule and cream and was fine in a few days. But now it's happened again and I'm wondering if it could be the beginning of vaginal atrophy? I've only had thrush maybe once before in my life so it would be strange for me to get it twice in the space of 2 months now. I'm only 46 but I've been on HRT for about 18 months now.
