What is an intrauterine device?
An intrauterine device (IUD) is a type of birth control that is inserted into your uterus. It is a small, flexible piece of plastic with a string on the end. It is inserted and removed by your caregiver. IUDs prevent sperm from reaching or fertilizing an egg. IUDs also prevent a fertilized egg from attaching to the uterus and developing into a fetus.
What are the most common types of IUDs?
- Copper: This type of IUD slowly releases a small amount of copper into your uterus. This IUD can remain in place for up to 10 years.
- Hormone-releasing: This type of IUD slowly releases a small amount of progesterone into your uterus. Progesterone is a hormone that is made by your body to help control your periods. This IUD can remain in place for up to 5 years.
What are the advantages of an IUD?
- Effective: An IUD is 98% to 99% effective in preventing pregnancy.
- Easily removable: The IUD can be removed if you decide to have a baby. You may be able to get pregnant as soon as the IUD is removed.
- Immediate: An IUD protects you from pregnancy right after it is inserted.
- Convenient: You do not have to stop sexual activity to insert it or worry about remembering to take your birth control pill.
- Safe: Copper IUDs are safer for some women than oral birth control pills. Examples include women who smoke or have a history of blood clots.
- Health effects: Hormone-releasing IUDs may decrease certain health problems. Examples include bleeding and cramping that happen with your monthly period.
What are the risks of an IUD?
- An IUD does not protect you from sexually transmitted infections. You may have cramps during the first weeks after you get the IUD. A copper IUD may cause your monthly period to be heavier or more painful. This is more common within the first 3 months after you get the IUD. You may need to have your IUD removed if your bleeding or pain becomes severe. You may have spotting between periods.
- There is a small chance that you could get pregnant. Sometimes the IUD cannot be removed after you get pregnant. This increases your risk of a miscarriage or an ectopic pregnancy. Ectopic pregnancy is when the fertilized egg starts to grow somewhere other than your uterus. There is a small risk of an infection within the first 20 days after the IUD is placed. Infection can lead to pelvic inflammatory disease. This can cause infertility. Your uterus may tear when the IUD is inserted. The IUD may slip part or all of the way out of your uterus.
How is the IUD inserted?
- The IUD is usually inserted during your monthly period. This may help decrease the amount of discomfort you have during the procedure. It also helps ensure that you are not pregnant. You will be asked to lie down and place your feet in stirrups. Your caregiver will gently insert a speculum into your vagina. This is the same tool used during a pap smear. The speculum allows your caregiver to see inside your vagina to your cervix. The cervix is the opening of your uterus.
- Your caregiver will clean your cervix with an antiseptic solution to prevent infection. You may be given numbing medicine. A long plastic tube is gently passed through your cervix and into your uterus. This tube has the IUD inside of it. The IUD is pushed out of the tube and into your uterus. You may have cramps as the IUD is inserted. The tube is removed after the IUD is in place.
How can I make sure my IUD is still in place?
An IUD has a string made of plastic thread. One to 2 inches of this string hangs into your vagina. You cannot see this string, and it will not cause problems when you have sex. Check your IUD string every 3 days for the first 3 months after it is inserted. After that, check the string after each monthly period. Do the following to check the placement of your IUD:
- Wash your hands with soap and warm water. Dry them with a clean towel.
- Bend your knees and squat low to the ground.
- Gently put your index finger inside your vagina. The cervix is at the top of the vagina and feels like the tip of your nose. Feel for the IUD string. Do not pull on the string. You should not be able to feel the firm plastic of the IUD itself.
- Wash your hands after you check your IUD string.
