Can Iud Fall Out? What Experts Say

An intrauterine device (IUD) sitting in the wrong place or coming out sounds alarming. But how often does this actually happen? The short answer is yes, IUDs can fall out, but it is not common. Research published in journals like Contraception reports that expulsion occurs in about 2 to 10 percent of users. Most cases happen in the first year, often within the first few months. Knowing the signs and what raises your risk helps you catch it early and avoid surprises.

What Does It Mean When an IUD Falls Out?

When doctors talk about an IUD falling out, they call it expulsion. This means the device moves from its correct place inside the uterus. It may come out partway or all the way. Partial expulsion is more common. The IUD shifts down into the cervix or the lower part of the uterus. Complete expulsion means the IUD comes out of the body entirely.

Partial expulsion is tricky because you might not notice it right away. The device is no longer doing its job. You lose pregnancy protection. The copper IUD and hormonal IUDs both have similar expulsion rates. The American College of Obstetricians and Gynecologists (ACOG) states that expulsion is most likely in the first year after insertion.

How Common Is IUD Expulsion Really?

The numbers vary depending on who you ask and which study you read. The CDC cites a typical expulsion rate of 2 to 10 percent for most IUD users. A large study in Obstetrics & Gynecology followed over 5,000 women and found a 5 percent expulsion rate within the first year. That means 95 out of 100 people kept their IUD in place.

Some groups have higher rates. Women who have never given birth have a slightly higher expulsion risk than those who have. Teenagers also show higher rates in some studies. The type of IUD matters less than the person using it. Copper IUDs and hormonal IUDs have similar expulsion numbers overall. One exception is the Mirena IUD, which some studies show a slightly lower risk of expulsion compared to the copper IUD. But the difference is small.

What Causes an IUD to Fall Out?

The uterus is a muscle. It can push the IUD out the same way it pushes a baby out during labor. For most people, this does not happen. But certain things make expulsion more likely.

Heavy menstrual bleeding is a known risk factor. The strong contractions that push out blood and tissue can also push out the IUD. Women with conditions like fibroids or endometriosis may have heavier periods and a higher expulsion risk.

Insertion timing matters too. IUDs placed right after childbirth or abortion have a higher expulsion rate. The uterus is still soft and enlarged. It contracts more strongly during this time. ACOG recommends waiting at least four weeks after delivery before insertion to lower the risk.

Uterine abnormalities like a septum or fibroids can change the shape of the uterine cavity. The IUD may not sit properly. This increases the chance it will shift or come out.

Can You Feel an IUD Falling Out?

Sometimes yes, sometimes no. Many people feel nothing at all. The IUD just slips out without pain or cramping. You might only notice when you check your strings or when your period comes earlier than expected.

Other people feel sudden cramping or lower back pain. The pain can be sharp or dull. Some women describe it as similar to menstrual cramps but more intense. If the IUD is partially expelled and sitting in the cervix, you may feel a foreign body sensation or pressure.

Bleeding can change too. Spotting between periods or heavier flow can signal a problem. But these symptoms are also common in the first few months after insertion. The key is to watch for a change from your normal pattern.

How to Check If Your IUD Is Still in Place

You can check your IUD strings at home. Wash your hands first. Insert one or two fingers into your vagina until you feel your cervix. It feels like the tip of your nose. The strings should be coming out of the cervix. They feel like thin fishing line or thread.

Here is what to look for:

• Strings feel shorter or longer than usual — this can mean the IUD has moved
• You feel the hard plastic of the IUD itself — this means it is partially expelled
• You cannot feel the strings at all — the IUD may have fallen out or moved higher

Do not pull on the strings. That can dislodge the IUD. If you are unsure, call your doctor. They can do an ultrasound or a pelvic exam to check placement. ACOG recommends checking your strings once a month, especially in the first few months after insertion.

What Happens If You Do Not Catch Expulsion Early?

If your IUD falls out completely, you lose pregnancy protection immediately. You can get pregnant that same cycle. If you have sex without a backup method, pregnancy is possible.

Partial expulsion is more dangerous because it is easier to miss. The IUD is still partially inside the uterus. It may still release hormones if it is a hormonal IUD. But it is not in the right position to prevent pregnancy effectively. The risk of pregnancy goes up. In rare cases, a partially expelled IUD can cause infection or injury to the uterine lining.

If you think your IUD has moved, use a backup method like condoms until you see your doctor. Do not wait. An ultrasound is the best way to confirm placement. The doctor can remove the displaced IUD and insert a new one if you want.

Does the IUD Type Affect Expulsion Risk?

Here is a quick comparison of the most common IUDs and their reported expulsion rates based on published studies:

The differences are small. Your personal risk factors matter more than the brand you choose. If you have heavy periods or a history of expulsion, talk to your doctor. They may recommend a hormonal IUD, which some studies suggest has a slightly lower expulsion rate. But the evidence is not strong enough to say one is clearly better.

Common Misconceptions About IUD Expulsion

A lot of misinformation floats around online. Let me clear up a few things based on what the evidence actually shows.

Myth: IUDs fall out during sex. This is not true. The IUD sits inside the uterus. The strings hang through the cervix into the vagina. Sex cannot pull the IUD out. The strings may shift slightly during intercourse, but that is normal.

Myth: If your IUD falls out, you will know immediately. Many people do not notice. The IUD can come out during a bowel movement or while wiping. You might see it in the toilet or on toilet paper. But some people never see it and only find out during a routine checkup.

Myth: You can push an IUD back in yourself. Never try this. Pushing a foreign object into your uterus can cause serious infection or injury. If your IUD comes out, call your doctor. They will remove the old one and insert a new one if you want.

Myth: Expulsion means you cannot use an IUD again. Not true. Many women who expel one IUD go on to have a second one placed successfully. The risk of expulsion is higher the second time, but it is still not guaranteed. Some doctors use ultrasound guidance during insertion to improve placement.

What to Do If You Suspect Your IUD Has Fallen Out

If you cannot feel your strings or you feel the hard plastic of the IUD, take these steps:

• Use a backup birth control method like condoms
• Call your doctor or clinic and schedule an appointment
• Tell them you think your IUD has moved or fallen out
• Do not try to remove it yourself

Your doctor will do a pelvic exam. They may use an ultrasound to see exactly where the IUD is. If it is partially expelled, they will remove it. If it is completely out, you can choose to have a new one placed right away or wait. Some clinics offer same-day replacement.

If you had unprotected sex around the time the IUD fell out, ask about emergency contraception. You can get a copper IUD inserted as emergency contraception up to five days after unprotected sex. It works as well as the morning-after pill and gives you long-term protection.
