Can a hormonal IUD get lost?
The hormonal coil lies well protected in the womb and suits the shape of the uterine cavity. Very rarely, the hormonal coil may become dislodged or be expelled (the risk of this is lower than with copper coils). Expulsion occurs in about 3% of women, and this tends to happen in the first few months, often without the woman noticing. Of course, with the Mirena® gone there’s no protection against pregnancy! It is therefore sensible to check regularly that the Mirena® is still in place, either by feeling for the threads against the cervix or by regular gynaecological examinations via ultrasound (see How often to check)
