IUD help please!!!

Hazel

So I am 18 years old I just got my iud about a month ago on the second of September. I was on my period when I got it and since then I have been bleeding everyday it has been mostly light spotting. I am not on my next period ( I am assuming because I am bleeding a lot more) and I am having excruciatingly painful cramps and my blood is a lighter pink bright red, it’s usually more darker. Im wondering if I should go to the doctor and get my iud checked or something because I have been bleeding so so much the last 2-3 days and it’s absolutely awful pain I can’t stand anymore and I feel like throwing up :( has anyone had this problem before? Thank you:(
