My mirena landed me in the emergency department in hospital at 2am this week. I had my mirena fitted 16 months ago. I haven't had children, so perhaps that's why the fitting was so painful, with lots of bleeding and vomiting. I had periods that lasted 20 days each for the first 3 months, and it took 8 months for my period to drop to a lighter bleed lasting around 8 days. I had cramps on and off during each month, and cramps after sex. I never felt really good, and my hair loss also seemed to be greater. I had it removed in the emergency department this week. Apparently it had become dislodged (unusual after 16 months) and had cut a vein in my uterus. I had extremely heavy bleeding for 5 hours before going to hospital, where the gynecologist pulled it out immediately (painful, but quick). I've had heavy bleeding for a few days since, but it is easing up now, thanks to 3 prescribed progesterone pills a day. I have a friend who loves her Mirena, but for me it did not work. My body seemed to fight it all the way.
