I had a mirena in a couple of years ago. I didn't like it, as I had a lot of pain some times, and went to my gp to take it out. He also put it in - he has ultrasound. I could only feel it the first couple of weeks, and then te strings disapeared. When I went to him to take it out, he couldn't get it out, the strings moved back or watever. I had to get my obgyn to do it in theatre.
