Intrauterine device (IUD) insertion can sometimes lead to unscheduled uterine bleeding. This occurrence is a common side effect, particularly in the initial months following placement. The bleeding may manifest as spotting, light flow, or heavier periods than usual.
Understanding this potential consequence is essential for patient satisfaction and continued IUD use. Historically, irregular bleeding has been a major reason for IUD discontinuation. Proper counseling regarding this possibility can improve patient adherence and acceptance of this highly effective contraceptive method.
