Cramps after IUD insertion--How long does this go on?!

Hello everyone! I had an IUD (Paragard) inserted Monday (this is my third day having it). I've been having terrible cramps, but it seems like they're getting a little less severe, or at least more easily managed with ibuprofen and a hot compress. Even so, I've already missed a couple days of work due to the pain.

How long did your cramps last after getting an IUD, and how did you deal with it?

In case it's relevant, I'm 24, never been pregnant, and I wasn't on my period during the insertion.
