Intrauterine devices (IUDs) are a popular form of long-term contraception. They are a highly effective method for preventing pregnancy, with a failure rate of less than 1%. However, in rare cases, an IUD may move from its original position in the uterus. Which can cause discomfort and decrease its effectiveness in preventing pregnancy. In this blog post, we will discuss the various factors that can cause an IUD to move.
Before we dive into the causes of an IUD moving, it is essential to understand what an IUD is and how it works. An IUD is a small, T-shaped device that is inserted into the uterus by a healthcare provider. There are two types of IUDs: hormonal and non-hormonal. Hormonal IUDs release progestin, a hormone that thickens cervical mucus and thins the uterine lining. Making it difficult for sperm to reach and fertilize an egg. Non-hormonal IUDs are made of copper, which creates an environment that is toxic to sperm, preventing them from fertilizing an egg.
Does the IUD move?
Before talking about the causes of the IUD movement. The IUD must be in the correct position precisely to ensure successful contraception.
The doctor confirms that the IUD is in its correct place, as the normal IUD is located inside the uterine cavity. However, the IUD can move from its place, causing symptoms of IUD movement. And this may be a result of incorrect installation or failure to adhere to the doctor’s instructions after IUD installation.
What Causes an IUD To Move?
- Incorrect placement: The most common cause of an IUD moving is incorrect placement. If the IUD is not inserted correctly, it may not be properly anchored in the uterus, which can lead to it shifting or even falling out. This is why it is crucial to have an experienced healthcare provider insert your IUD.
- Uterine contractions: The uterus naturally contracts, which can cause an IUD to shift or move slightly. This is typically not a cause for concern, as the IUD will usually settle back into place on its own. However, if you experience pain or discomfort, it’s best to consult with your healthcare provider.
- Menstrual bleeding: During menstrual bleeding, the cervix opens slightly, which can cause an IUD to move. This is another reason why it’s essential to check your IUD strings regularly to ensure that it’s still in place.
- Sexual activity: Sexual activity can also cause an IUD to move. This is especially true if your partner’s penis hits your cervix during sex, which can displace the IUD. Using a condom can help reduce the risk of this happening.
- Physical trauma: Any physical trauma to the abdomen or pelvis can cause an IUD to move. This includes activities such as contact sports, heavy lifting, or falls.
- Weight loss: Significant weight loss can cause an IUD to move. This is because the uterus may shrink with weight loss, which can cause the IUD to shift or become dislodged.
What Are The Symptoms Of IUD Moving Out Of Place?

After Knowing about the causes of an iud to move, we will discuss the Symptoms of an IUD that has moved out of place including:
Pain During Sexual Intercourse
There may be a slight change in the sensation during sexual intercourse. But there is a difference between this and feeling pain during sexual intercourse.
Pain during sexual relations may indicate that the IUD has moved from its place and moved to another place where it is not supposed to be, such as the cervix. Then you should know the causes of IUD to move.
Menorrhagia or Bleeding
The menstrual cycle changes naturally after the insertion of the IUD, and this change varies according to the type of IUD.
If a hormonal IUD is installed, it is expected that the menstrual cycle will become lighter than before, while if a copper IUD is installed, it is expected that the menstrual cycle will be heavier than it was in the past.
But also one of the symptoms of the IUD moving from its place is the release of bloody spots at times other than usual, or the abundance and pain of menstruation unusually.
If these symptoms appear, it is recommended to see a doctor. To make sure that the IUD is in the correct place.
Abnormal Vaginal Secretions
Vaginal secretions are normal most of the time. But if strange secretions come out for a woman, or they have an unpleasant odor. This may indicate that the IUD has moved from its place, or something else.
IUD Strings Changing Places or Losing Their Place
After installing the IUD, the doctor leaves its threads extending somewhat into the vaginal canal, 2 or 3 centimeters; To facilitate the removal of the IUD when needed.
Also, it allows the woman to check that the IUD is in place from time to time.
If a woman loses the ability to touch the IUD threads inside the vaginal canal, this may be a symptom of the IUD moving, or it may be normal, as the threads bend over time.
Some specialists recommend that you see a doctor if you are unable to touch the threads of the IUD inside the vaginal canal.
Feeling Crampy or Severe Pain
Most women feel cramps in the lower abdomen after IUD insertion, which is normal.
This feeling of colic may increase after the copper IUD is installed.
But if the colic gets worse, or lasts longer than usual, this may be a symptom of the IUD moving that calls for a visit to the doctor.
Feeling The Presence Of IUD during sexual relations
It is assumed that the man will not be able to feel the presence of the IUD inside the uterus during sexual relations.
If the man feels the IUD, this may mean that the IUD is inside the cervix, unlike its normal location inside the uterine cavity.
Conclusion :
In conclusion, an IUD is a highly effective form of long-term contraception. But it’s important to be aware of the causes of an iud to move. If you experience any pain, or discomfort, or notice that your IUD has shifted. It’s essential to contact your healthcare provider. They can help determine if the IUD is still effective in preventing pregnancy and if any action needs to be taken to reposition it.
