Cancer of the cervix or uterus or suspected cancer would certianly rule out the insertion of an I.U.D. Copper I.U.D. s should not be inserted if there is a proven allergy to copper or any disorder of copper metabolism such as Wilson s Disease. Your doctor will explain the significance of this and other conditions which may involve copper. Common reactions which can occur with the use of an I.U.D. include post insertion pain and cramping, complete or partial expulsion of the I.U.D., breakthrough bleeding which occurs in between periods, heavy or prolonged periods, pelvic inflammatory disease and pregnancy. Fainting attacks associated with low heat rate. Less common reactions can include perforation of the uterus or cervix, inflammatory conditions of the uterus, the cervix or vagina, loss of periods, painful periods and pain on intercourse.
Anaemia can occur due to a heavy loss of blood during period time.
You should have regularly yearly check ups with your doctor when using an I.U.D. and be on the lookout for the presence of persistent, unusual and uncomfortable pelvic symptoms and signs. Remember that a light or missed period associated with pain may indicate that the I.U.D. has failed and that you are pregnant.
