An intrauterine device (IUD) is a small plastic T-shaped device used for birth control. It is inserted into the uterus where it stays to prevent pregnancy.
An IUD is usually inserted by your health care provider during your monthly period. Either type can be inserted quickly and easily in the provider's office or clinic.
The strings have two purposes:
This procedure can cause discomfort and pain, but not all women have the same side effects. During insertion, you may feel:
Some women have cramps and backaches for 1 to 2 days after insertion. Other may have cramps and backaches for weeks or months. Over-the-counter pain relievers can ease the discomfort.
Why the Procedure is Performed
IUDs are an excellent choice if you want:
But you should learn more about IUDs when deciding if you want to get an IUD.
An IUD can prevent pregnancy for 3 to 10 years. Exactly how long the IUD will prevent pregnancy depends on the type of IUD you are using.
IUDs can also be used as an emergency contraception. It must be inserted within 5 days of having unprotected sex.
While uncommon, IUDs carry some risks:
Before the Procedure
Talk with your provider about whether an IUD is a good choice for you.
Also ask your provider:
For the most part, an IUD can be inserted at any time:
If you have an infection, you should NOT have an IUD inserted.
Your provider may advise you to take an over-the-counter painkiller before getting the IUD inserted. If you are sensitive to pain in your vagina or cervix, ask for a local anesthetic to be applied before the procedure starts.
After the Procedure
You may want to have someone drive you home after the procedure. Some women have mild cramping, low backache, and spotting for a couple of days.
If you have a progestin-releasing IUD, it takes about 7 days for it to start to work. You do not need to wait to have sex. But you should use a backup form of birth control, such as a condom, for the first week.
Your provider will want to see you 4 to 6 weeks after the procedure to be sure the IUD is still in place. Ask your provider to show you how to check that the IUD is still in place, and how often you should check it.
An IUD can slip partly or all of the way out of your uterus. If this happens, contact your health care provider right away. Do NOT try to remove an IUD that has come part of the way out or has slipped out of place.
