Confused iud stuck

Rebecca
I went in to see my ob yesterday because since I got my iud in last year it's cause back pain so I wanted to get it removed. She went to remove it and it was stuck she yanked on it for like an hour and it would not come out. She did and ultrasound to see where and she can't tell. We'll she scheduled me for a d & c. Where I'm confused is I'm in a lot of pain still from her yanking on it today i checked to see if i could tell if it was hangin out. I could not find the strings. Do you think it could be up in me now? I have not felt it dislodge or anything. And I haven't seen it. What's your thoughts???
