My IUD is causing constant spotting

Hi everyone. I got an IUD in March and I have had constant spotting since. Not a full on period yet, but spotting for about 2 days every couple of days. It's already pretty annoying, as I hate having to wear pads/liners all the time. Already getting a lot of clothes ruined. Has anyone else had this issue? I have the Skyla. I just want normal periods again. I switched from the pill because I was getting headaches. Help! :)
