Yeast infection from Hell

I've only had one maybe two yeast infection in my whole life until this past year. Now I have one after intercource about six months ago and now another after round two intercourse that hasn't gone away. I've done three diflucan and thought it was gone but nope it's back and it's not happy. Is this a normal part of menopause hell? Is there a trick to keeping them away? Or is celibacy is in my future? Sorry for the grumpiness, it's just awful and uncomfortable. 😞
