recurring yeast infections for 5 months

i’m at my wits end at this point. countless gyno appointments, probiotics everyday, fixing my diet, nothing changes. i’ve been getting a yeast infection before my period for 5 months now. i feel like i’m in absolute misery. i’m about to go to target to pick up non scented laundry detergent to see if that will really help my issue. i’ve taken countless diflucan pills, creams, and boric acid pills and nothing seems to prevent them from coming back! i’m praying this is the reason why, and my gyno even told me that’s a big reason for a lot of women. i just wanna know if anyone else has this issue cause i feel so alone
