2 doses of diflucan didn’t work

okay, so i am not sexually active currently, and in this time frame, i got a yeast infection. the first yeast infection i’ve ever gotten. i went to the doctor and i was given diflucan, took the two doses three days apart, and then started my period. the doctor said periods usually clear up yeast infections, but i am still experiencing mild itching and burning almost seven days after the second dose. i cannot make it back in to the doctor until monday. has anyone else ever experienced this? should i try using monistat 7-day until i can make it in?
