should i get it check or no?

I got my IUD but in little over a week ago. I bleed for a day after that then stopped well 3 days ago I started bleeding again with major cramps. the next day I was throwing up and in a ball all night because my whole stomach hurt. I've had two kids and this pain was so much worse. well the pain has lighted up a little. but my question is, is this normal or should I got in to get it check.
