i got my mirena IUD in last year, Ive been getting a lot of the side affects like headache,mood swings,depression,weight gain,hair lost,nausea,really bad sharp pains,insomnia,and really heavy periods and, i couldn't feel the string...so yesterday i went to the hospital with the sharp pain and they did a CT on me.....get this, they told me that the IUD is in the pelvis,however, it is outside of the uterus and adjacent to the sigmoid colon and, a low density lesion in the adnexal region probably representing an ovarian cyst which has ruptured!!!! so they sent me home with some pain killers and told me to call the doctor that put it in......ohh yeah and I forgot to tell you they said i need to have surgery to remove it.(how nice!!!) GOOD LUCK TO EVERYBODY
