How bad are IUD period cramps supposed to be???

Grace • Thankful for what I have, thankful for what I can get.
My period cramps feel like I'm getting my IUD/abortion procedure all over again and it's so bad that I've begun crying from the pain. I've never had very bad cramps to begin with but this is nearly unbearable. So tell me exactly how terrible are these cramps supposed to be because I'm starting to become worried.
