Yeast infection

I've had a yeast infection for months now and I told my mom we went to the doctor 3 times and the medicine they prescribed me didn't work and we just moved to a new state so I dont have no family to ask and my mom think something else is wrong but she won't take me to the doctor... does anyone know anything that worked or helped with a yeast infection because I'm a virgin and the doctor said I tested positive for yeast infection
