Update - I went for a pelvic ultrasound today, but there was nobody around to read the results properly, so now I have to wait until Friday to see my regular doctor again and find out where the damn thing has gotten to. The hospital said they would call me if they found anything serious - but in my mind it is serious already! I'm not a wimp, but really - I have an IUD missing from my uterus! I have noticed all the doctors and nurses I have dealt with have a very casual attitude about this - tells you something about how often this happens. I bet I have to wait until after Christmas to get this thing removed. FYI, I read some other posts today about the side effects of MIRENA. I also have no sex drive - I think my husband has reached his limit. I have mood swings and am often angry with my kids and husband for no real reason. Was never depressed before MIRENA.
