I continue to have intermittent vaginal itching. I have had a yeast infection years ago that improved with monistat 1. At that same time I also started my menstral cycle. The intermittent itching and burning started 10 days ago then I noticed cottage cheese like discharge. 4 dad ago I used monistat 1 and I've improved somewhat, but at random times I'll have uncomfortable itching again. Could I not be responding to the monistat 1 this time since it is not during my menstral cycle? Also I do have the mirena IUD and have not had a menstral cycle since it was placed Oct 2012.
