Right now I have in the Mirena and I've heard some scary things about it. I've heard it can pierce through the uterus wall and cause infection among other things. I know of a woman who had to have it removed because it damaged her uterus. I havn't had a "normal" period since before I got pregnant. I also have pelvic cramping often. Should I go se a GYN and get it removed or am I just peranoid??
