IUD and pregnancy

Katie
So I've had my IUD in place for 4 years now. After a night of rough sex I have had cramps and nausea. Side note- this happened 10/28 I was also ovulating at the time. What are the chances that the little sucker moved and I got pregnant? Just wondering on anyone's opinions. Will test in the morning since it's close to my period starting. And if it makes any difference I have paragard.
