IUDs are far more easily reversible than male or female sterilization. The IUD commonly causes irregular periods. The number of bleeding days may be greater than normal. If your bleeding pattern is bothersome to you, contact your clinic or clinician. There are medications which may give you a more acceptable pattern of bleeding.
Some women stop having periods completely.
There may be some cramping or pain at the time of insertion. It is costly to remove and reinsert a new IUD each year. You can get an IUD from your clinician, health department, or family planning clinic. Not all clinicians insert IUDs. Check in advance.
