confuzzled.

ok well ive been having nonstop vaginal infections . it started with bv after the metro gel i got a yeast infection along with anal itching . now its in a constant cycle and sometimes i have them simultaneously to the point where i dont really know what i have. O.o its very depressing. i dont really know if the anal itching is a result of yeast or from an upset stomach as i notice that it itches almost every day despite of taking 200 mg diflucans and using nystatin . anyone know what i can do to stop BV . my diet isnt horrible im relatively healthy with lots of moderate to light allergies. thank you
