I'm sorry you have been through so much. I hope your surgery goes well and that you feel better soon.
The possibility that these IUDs are defective and are releasing more than the advertised trace amount of progesterine (sp?)is very worrisome to me, as I was nursing for most of the time that I had this IUD. I know it sounds kind of crazy, but I wish I would have kept the IUD after I had it removed just in case, heaven forbid, it could have impacted by baby.
