Burning sensation while urinating is often a sign of urinary tract infection as opposed to vulval fungal infection.
The topical cream and tab.fluconazole you tried are both anti fungal and if your infection is bacterial, they will not help.
I would suggest a urine routine test to analyse the degree of infection and based on that a course of antibiotics can be started.
In the meanwhile, drink plenty of water and urinate frequently.
