DD - early 20s has had thrush twice in fairly quick succession. Went to GP who prescribed a pill x 2. I think she had it about a year ago too as she’s at uni and is only home in the holidays so I sort of remember her talking about it and getting the pessary.
GP did swabs but to rule out std (v unlikely as she’s gay - has a female partner atm but has had pv sex albeit a year or so ago)
I did advised cutting down on sugar, as I know that can aggravate things but wondering if anyone else has suffered.
