IUD and labor pains

Hi ladies! So I had a child back in May. I got the paraguard IUD inserted a few months afterwards. Ever since I have been getting this excruciating pains similar to labor contractions. I would have to stop and breathe and sometimes I would even fall to my knees! I went to the doctors and they did a placement check with ultrasound and said everything was in correctly but the pain still keeps occurring. Has anyone experienced this? I don’t want to feel this pain but I also want to try and keep it in. Please help!
