Ok I now have the report...
With the culture and sensitivity they only isolated candida (thrush).
They also did a gram stain for bacterial vaginosis and graded it as Hay's grade 2.
Grade 1: lactobacillus predominates
Grade 2: mixed flora with some lactobacillus present, but gardnerella or mobiluncus also present.
Grade 3: predominantly gardnerella or morbiluncus, few or absent lactobacillus.
To be honest I would have expected grade 2, since I'd been taking daily vaginal probiotics up until 2 days before the swab, so they likely just picked up the ones I was putting up there in and I already knew there would be gardnerella. It's annoying that they could culture the gardnerella ans test sensitivity though.
My gp has prescribed me some clotrimazope cream and 1 x 500mg pessary, I will probably use the high dose pessary as soon as I stop the antibiotics.
