INFORMATION
While using the IUD you can use tampons and/or towels.
You may get some period-type pain and possibly some light bleeding for a few days afterwards.
The IUD 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.
It is very unlikely that the IUD will come out but if you are worried and can feel the IUD itself, or cannot feel the threads you should see a doctor or nurse straight away.
You will then only need to go back when the IUD needs to be replaced (5 to 10 years depending on the type of IUD).
You should go back to the or doctor or nurse if you notice any of the below symptoms:
The IUD can be fitted at any time in your cycle if it is certain that you are not pregnant. It may also be possible to fit the IUD as emergency contraception. Check the emergency contraception calculator to work out if it is not too late to fit an IUD.
As soon as the IUD is fitted then you will be protected immediately. You will be asked to take a pregnancy test before the IUD is fitted and another three weeks later if there is a pregnancy risk.
The IUD must be removed by a trained doctor or nurse, the procedure should be less painful and quicker than having the IUD fitted. If you are not going to have another IUD you will need to use additional contraception, such as condoms, for the seven days before the IUD is taken out if you do not want to become pregnant.
Your fertility should return to normal as soon as the IUD is removed.
