I had the mirena put in in August of 2009 after my son was born. I had it in for 4 years. With the last year I started getting the worst problems. I started itching in January 2012 and the cramps they started getting worse with my periods, than with my ovulation cycles and than it was almost everyday. It was out around August or September 2012 and though most of the symptoms are gone, I can't stop itching.
