If you’re 40 or over when you have an IUD fitted, it can be left in until you reach the menopause or you no longer need contraception. Check your IUD is in place a few times in the first month and then after each period, or at regular intervals. An IUD has 2 thin threads that hang down a little way from your womb into the top of your vagina. The GP or nurse that fits your IUD will teach you how to feel for these threads and check that it’s still in place. It’s very unlikely that your IUD will come out, but if you cannot feel the threads or think it’s moved, you may not be protected against pregnancy. See a GP or nurse straight away and use additional contraception, such as condoms, until your IUD has been checked.
