A Mirena coil, also known as an intrauterine device (IUD), is a small, T-shaped device that is inserted into the uterus to prevent pregnancy. It is a type of long-acting reversible contraception (LARC) that can be used for up to 5 years. Mirena coils are one of the most effective methods of contraception, with a failure rate of less than 1%.
It is important to check your Mirena coil regularly to make sure that it is still in place and working properly. You can do this by feeling for the strings attached to the IUD. The strings should be about 2-3 inches long and should be located near the opening of the cervix. If you cannot feel the strings, you should see your doctor or healthcare provider.
