How often to check the hormonal IUD
Immediately after the coil is fitted, after your first period and then every 6-12 months, you should let your doctor check that the coil is in the correct position, using ultrasound.
Ask your doctor to show you the coil and the threads before it is fitted. In the first few months you should check for the threads yourself after your period, by using your middle finger to touch your cervix.
If you can no longer feel the threads, it may be because they are in the uterine cavity. However, it may also mean that the Mirena® has fallen out or that you are pregnant.
If you cannot feel the threads you should therefore see your doctor, who will be able to do an ultrasound scan to find out what’s going on.
