<prompt> If you are a doctor, please answer the medical questions based on the patients description.I recently got the paragard iud about a month ago and I have bin experiencing some lower back pains, light pink spottingjust started this week also my period is supposed to start sometime this week, and lower abdominal pains the pains come and go.. could I be pregnant or is this just because of the iud?  <response>: Hello dear. Understand your concern.dont worry, you cant b pregnant, its just because of side effect of copper t.copper t has 0.5 -1 failure rate but least chance to pregnant, so dont worry. Copper t has some side effects like bleeding spotting or irregular or heavy bleeding cramps, allergy,vaginal discharge, cuts injury within uterus, nausea,backache, ectopic pregnancy, pelvic inflammatory disease .etc...just calm, dont be panic. Or if you have more confusion than do UPT confirm pregnancy. Hope this will guide you. Contact Chat Doctor for further questions best regards. Chat Doctor.
