"I had the Paraguard put in by my Midwife, who recommended I take 3 Motrin beforehand. It was excruciating and didn't let up. It felt like a knife was inside my cervix, and the pain made me nauseous, dizzy, shaky, and see stars. I felt like I was going to pass out that night. The next day when I called, they ordered an emergency ultrasound. My body was trying to push the IUD out and it "migrated" so that instead of the top of the T laying horizontal and flat, one side was poking into me. They removed it immediately and the removal was also painful, but I had relief from the stabbing pain right away. She looked at the device and it had even bent (in 24 hours). I would not recommend this device."
