I am experiencing the same thing. My doctor can still see my iud in my uterus but can't get it out. He has even tried to deaden my cervix to get it out and it did not work so now I have to have surgery. I am also having really bad headaches, lots of cramping, very bloated and dizzy. My doctor is not really sure why he can't get it out since he can see it on the ultrasound. Any suggestions, I feel so lost right now.
