Should I get my IUD removed?

Am

It's been almost a year now since I got my Kyleena IUD inserted. And I'm still getting really bad cramps (when before I had it, my cramps were at a 2.5/5 in pain level). Now I'm literally out of breath sometimes, or having a cold sweat because of the pain and need to move to the side to wait for it to pass.

I missed my period 2 months ago but got it last month for only 2-3 days. I'm due for my next period in 8 days but the pain and the horrible cramps make me wonder if this IUD is worth it.

I'm in a committed relationship with my boyfriend, but we aren't ready to have kids yet. I don't know what to do or if I should continue to wait and see if my body will adjust to it.

(I also never got an ultrasound afterwards. I was too busy preparing for my 2nd year in university)
