Paraguard iud painful

Patient: I had the Paraguard IUD inserted on the December 19. I looked up the product online and had intense conversations with my doctor about the product, and we both agreed that it was the right move for me. But now, I am rethinking my decision. I been having some real serious pain in my lower admomen(which i have been having before the IUD was inserted) the pain has been constant and i have been spotting and releasing some huge blod clots. I am unsure of what to do now..
