Hello and welcome CP
I'm afraid it is pretty common to start getting thrush , BV and Urinary tract infections in peri and post meno as the natural flora of the vaginal area starts to atrophy so is far more prone to infections etc.
It's wise to practise ' Be kind to your bits': take showers not baths, avoid anything scented, drink plenty of water, wear cotton pants and avoid wearing very tight trousers. There are gels that can help keep the area moist and healthy - Multi gyn Actigel, Hyalofemme etc.
Try not to worry - we are here to help. DG x
