New users of the intrauterine device (IUD) are most likely to discontinue use within the first six months after insertion. The most common reason for discontinuation of the copper IUD is symptoms related to bleeding. Research looking at disturbances in bleeding patterns among new IUD users is sparse and dated. Perceived changes in vaginal bleeding may impact method satisfaction, acceptability, and continuation. There is a need for updated research evaluating changes in bleeding patterns in order for providers to better counsel patients on what to expect during the months after initiation of an IUD.
