Yeast

Hi guys so I got my first yeast infection and it’s been there for 2 month. I took 3 diflucan in the span of 2 months and monstat, etc I visited 3 gynos.. how do you know if it’s going away. Also every time I put in the suppositary it gets itchy I have to wash it out.. is it supposed to itch in the night? How does it go away? Does it go away slowly or does it stop all of a sudden
