Can the IUD come out or get stuck?

The IUD must be fitted by a specially trained clinician who carefully puts it in the correct position. There is a small risk (about 1 in 1000) at the time of insertion that it can go into or through the muscle of the uterus (perforation) and end up in your pelvis. There is also the possibility (1 in 20) that it will be pushed out of your uterus and come out of your vagina (expulsion) . We advise that women check that they can feel the threads of their IUD 6 weeks after it has been inserted and to seek medical advice if you experience unusual pain, bleeding or discomfort, particularly in the first month after insertion.
