Are you sure they are yeast infections???Could he of possibly slept with someone else & has brought an STD into your life?If you haven't been checked by your DR call them & get it looked at a simple pelvic exam along with tests will answer most of your questions,don't treat yourself at home since they are reoccuring you really need to seek medical advice,it can also not be yeast infection but BV which is treated differently than a yeast infection.Maybe the Mirena needs to be taken out.A sign of yeast infections is pregnancy & diabetes.
