Still having bad cramps 6 months after IUD

Kait

Got an IUD put in in October. It was excruciating and so were the cramps days after. Now 6 months later I still get cramps that are worse than they were before I had the IUD the week before my period starts. During my periods cramps are not very bad. Will these cramps ever get better? My doc said the IUD was supposed to lessen cramps and shorten periods but it seems to being doing the opposite so far.
