I was recently diagnosed with Candida Glabrata in my bladder. Prior to my diagnosis I was having UTI symptoms ... frequency, urgency, etc. I was put on two rounds of Antibiotics (worse thing they could have done) and referred to a urologist. I was given a cystoscope, ultrasounds, CT-scan, and urodynamic testing while my Urologist waited for my culture results. When the culture came back for Candida Glabrata, I was referred to an Infectious Disease specialist. They know what strains respond to which medications and how long you need to take the medications. My urologist said that I would "probably" be prescribed a day or two of Diflucan, but this particular strain is really resistant to drugs and the Infectious Disease specialist said to start off by taking it for 14 days and then come back for tests.
Point being ... I'd suggest a good Infectious Disease specialist to diagnose and treat. They know what they're doing with regard to this stuff and will save you time and pain in the long run.
In addition, I wouldn't recommend drinking a lot of Cranberry juice or anything else with a lot of Sugar in it if you're fighting off yeast in your bladder. Cranberry juice/pills and D Mannose only help with bacterial infections in the bladder.
