An intrauterine device (IUD) is inserted into the uterus through the vaginal canal and cervix using a tube or slider. Before insertion, a doctor performs a bimanual exam and sounds the uterus to determine its position and the depth of the uterine cavity. The IUD is then inserted to the indicated depth, and the doctor cuts the threads to a length that allows the patient to check its position. Once in place, the IUD’s arms open into a “T” shape and strings hang down through the cervix into the vaginal canal. The provider can then use these strings to remove the IUD when it expires or if the patient wants it taken out.

You may notice changes in your menstrual cycle after the IUD is inserted. This is normal and these changes can be temporary and may go away as your body gets used to the IUD. Some patients report no longer getting a cycle or having a very light period, if these changes concern you, talk with your health care professional.

Patients have also reported headaches, nausea, breast tenderness and mood changes a few weeks after the IUD is inserted. These are normal side effects when new hormones are introduced, it should get better as your body gets used to the medication.

If you develop severe pelvic pain, unexplained fever or unusual discharge you should contact your provider to let them know. If needed the IUD can be removed if the issues become too great. You should also let the provider know if you start to feel the IUD in the vaginal or cervix.
