I have the mirana put in around the end of last year. I have had a period you would say or light bleeding since March. I Started having light bleeding and been doing so for about a week and half. Today I notice a bout almost quarter size chunk of flesh like blood it was very thick. No pain just body been feeling sore but figured it was due to the bed I had cause it was my back and neck and chest that felt sore and well a few times my stomach did as well. What could this be?
