I have a yeast infection and began a 3-day treatment with monistat last night. I think I'm starting my period today. Instructions on the box say not to use with tampons. Does that mean just not after inserting the suppository (which I wouldn't do) or not at all during the course of treatment? Also, is there any point to treating this during my period, as it will only provide a moist environment for the yeast to grow?
