I have mirena and am having it removed tomorrow. I had severe abdominal pain tonight and went to the hospital and they told me the mirena caused me to have endometriosis. I thought mirena was supposed to help endometriosis? I have also had numerous bad side effects. I have had severe cramping, migranes, weight gain, major mood swings, anxiety, and depression. My doctor prescribed me lexapro and zanex but I never had these problems before mirena. How do I get in on a class action lawsuit?
