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.
Alternative Names
Mirena; ParaGard
Description
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 provider slides a plastic tube containing the IUD through the vagina and into the uterus.
- Using a plunger in the tube, the provider pushes the IUD into the uterus.
- The provider removes the tube, leaving two small strings that dangle outside the cervix within the vagina.
The strings have two purposes:
- They let the provider or woman check that the IUD stays properly in position.
- They are used to pull the IUD out of the uterus when it is time to remove it. This should only be done by a health care provider.
This procedure can cause discomfort and pain, but not all women have the same side effects. During insertion, you may feel:
- Little pain and some discomfort
- Cramping and pain
- Dizzy or light-headed
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.
