I've had mirena for about 4 years now, since I've had this put in, I have not had a period. my obgyn says this is normal, but for the last couple of days, I have been spotting a lot. and had a lot of cramping, which they say is normal too, but I've been having some pain during intercourse, and bleeding afterwards. it's becoming uncomfortable now, I sometimes get random pains in the pelvic area, so sharp I can't move for a minute or two. I heard about this product, and tending to attach it self onto the uterus wall. is this true? and is this happening to me???
