Yeast Infection - 3dpo

Sorry TMI!! Just curios if anyone has experience a rapid onset yeast infection a few days after ovulation? I've never had one come on this quickly or be this bad. I'm obviously treating it now with 7 day over the counter meds since prescription  diflucan is not safe to take when TTC.  Just curios if the hormone surge could have caused it since I've never had one just after ovulation.
