IUD Cramping After 2 Years

Ca

I have the Paragard IUD, and I still get random cramping even thought I’ve had it for nearly 2 years now. They’re not anything that makes me double over in pain and agony, and Ibuprofen usually gets rid of them within an hour. I also get them after sex sometimes. I was just wondering if anyone else still experiences the cramping past the first 6 months, or if it’s abnormal and something to worry about.
