Check w gyn/PCP: First step is have an exam by your health care provider her put the IUD in. IUD's can become dislodged or cause pelvic inflammation/infection, perforation or other serious problems. So again get examined.

Need urgent exam: Many things could cause LLQ abdominal pain, among those are ovarian cyst, pelvic infection, bladder infection, diverticulitis, colitis and constipation. More history and an exam is needed to make a diagnosis and recommend treatment. IUD's have been reported to become displaced and to rarely penetrate the uterine wall, but you need to consider all the options.
