I had my mirena fitted April 08, and four days ago I had it removed... What a relief! A week after it was fitted, i went to a gyn because of the cramps and they scanned my uterus. Everything was in perfect order. But the cramps didn't stop and I was bleeding more or less all the time. Sometimes I could feel it when having sex, and my boyfriend did too. I also had that PMS feeling for about three weeks before having my period, getting irritating and moody. Before period I got acne and blisters in my mouth (never had any of it before!). I had to convince the doctor to take it out, she said it was such a good birth control. Now I am feeling happier with no mirena in my body. But I am bleeding quite heavily. I can't find any information about what happens to your body when mirena is removed?
