Cramping 2 weeks after insertion

Mishelle
I got my IUD on the 17th and I cramped and spotted for four days afterward. I was fine until about three days ago when I started cramping again and spotting. My period is due in a little over a week and I usually get cramps beforehand but this is a more consistent pain like when I first got it inserted. I don't want to get a doctor's appointment just for pre-period cramps. Has anyone else experienced this???
