The IUD (IUCD, Copper-T)
The IUD is a small object or device that is inserted into the womb by a specially trained health worker or midwife. Once in the womb, the IUD prevents the man’s sperm from fertilizing the woman’s egg. The IUD can stay in the womb for up to 10 or 12 years (depending on the kind of IUD it is) before it must be removed and replaced. An IUD can be used without the man knowing you are using it (although sometimes a man can feel the strings).
The most common IUDs are made of plastic, or plastic and copper.
IUDs can be used safely by women who are breastfeeding.
Do not use an IUD if you are unable to get to a health center or clinic where you can have the IUD removed if necessary.
Do not use an IUD if you:
- are pregnant or might be pregnant.
- have an STI or are in danger of getting an STI. (This includes any woman who has more than one partner, or whose partner may have other sex partners.)
- have a lot of bleeding and pain during your monthly bleeding (a progestin IUD may be better).
- are very anemic (a progestin IUD may be better).
Wait for at least 3 months before using an IUD if you have had an infection in your tubes or womb, or an infection after giving birth or after having an abortion.
Common side effects:
You may have some light bleeding during the first week after getting an IUD. Some women also have longer, heavier, and more painful monthly bleeding, but this usually stops after the first 3 months.
How to use the IUD:
An IUD must be inserted by a specially trained health worker after doing a pelvic exam. The best time to have the IUD put in is during your monthly bleeding. After childbirth, it is best to wait 6 weeks for the womb to return to its normal size and shape before getting an IUD. Occasionally an IUD will slip out of place. If this happens, it will not be effective in preventing pregnancy, so it is important to learn to check your IUD to make sure it is still in place.
How to check the IUD strings:
- Wash your hands.
- Squat down and reach as far as you can into your vagina with your 2 fingers. Feel for the IUD strings, but do not pull them.
- Take out your fingers and wash your hands again.
Warning signs for problems with an IUD:
Pelvic inflammatory disease is the most serious problem that can result from having an IUD. Most infections happen in the first 3 months, usually because the woman already had an infection when the IUD was put in. Or it may happen because the health worker did not put in the IUD under clean conditions.
If you have any of the following signs, you should see a health worker trained to insert IUDs and to treat complications, or go to a hospital immediately:
- Your monthly bleeding is late.
- You have pain in your lower belly or pain during sex.
- You have a heavy or bad-smelling discharge from the vagina.
- You do not feel well, or have fever or chills.
- Your IUD string is missing, or is shorter or longer than usual.
- Your partner can feel the IUD (not just the strings) during sex.
To stop using an IUD:
When you want to stop using an IUD, it must be removed by a trained health worker. Never try to remove an IUD yourself. You can become pregnant as soon as it has been removed.
