An intrauterine device (IUD) is supposed to prevent pregnancy, but occasionally a woman with an IUD in place may become pregnant. The presence of an IUD increases the risk for complications.


Complications that can occur in a woman who becomes pregnant with an IUD in place:

(1) ectopic pregnancy (fallopian tube, ovary, elsewhere)

(2) miscarriage

(3) infection with sepsis

(4) premature labor and delivery


If a woman becomes pregnant while an IUD is in place, then it should be removed as early as possible if this can be done safely.
