The IUS is a small, T-shaped plastic device, which contains the hormone progestogen to control your fertility. The device is put into the uterus (womb) through the vagina by a specially trained doctor or nurse.
The IUS contains the hormone progestogen and works in three ways to prevent the egg being fertilised by sperm. Read more
Your periods may be lighter, shorter, or they may stop completely

It does not protect against STIs

Some services may be able to fit it at the same appointment, or you may need a second appointment.
Fitting the IUS (shouldn’t take longer than 5 minutes):
The doctor or nurse may discuss painkiller tablets and/or using local anaesthetic to make the fitting more comfortable.
Currently there are four brands of IUS – Mirena, Kyleena, Levosert and Jaydess. Some brands work for five, four or three years.
If you get periods while using the IUS you can use tampons and/or towels.
You may get period-type pain and possibly some light bleeding for a few days afterwards.
The IUS has two threads which hang through the opening at the entrance of your uterus (cervix). You should check the threads a few times during the first month and then at least once a month.
Once the IUS is fitted, you will need to go back to the doctor or nurse after three to six weeks for a check-up.
It is very unlikely that the IUS will come out but if you are worried or cannot feel the threads you should see a doctor or nurse straight away. You will then only need to go back when the IUS needs to be replaced (3 to 5 years depending on the type of IUS).

The IUS can be fitted any time in your cycle if it is certain that you are not pregnant. If fitted in the first seven days of your menstrual cycle you will be immediately protected against pregnancy. If it is fitted at any other time, you will need to use an additional method of contraception (such as condoms) for the first seven days.
If you have a short menstrual cycle, where your period normally comes every 23 days or less, you will have to start the IUS in the first six days (because you might ovulate early in your menstrual cycle).
The IUS must be removed by a trained doctor or nurse. The procedure should be less painful and quicker than when the IUS was inserted. If you are not going to have another IUS you’ll need to use additional contraception, such as condoms, for the seven days before the IUS is taken out if you do not want to become pregnant.
Your fertility should return to normal as soon as the IUS is removed.
