Many people choose an IUD for long term, low maintenance contraception, but worry about whether it can fall out. Understanding how placement works, what normal expulsion feels like, and when to contact your clinician helps you feel more confident and prepared.
Below is a focused guide that explains the likelihood, warning signs, and practical steps you can take if you are concerned about your IUD moving or coming out.
| Aspect | What It Means | Likelihood | Action if Concerned |
|---|---|---|---|
| Spontaneous expulsion | The IUD partially or fully slips out through the cervix | Low to moderate within first year, higher in first few weeks | Check strings after each period, use backup contraception, call your provider |
| Malposition | The IUD is in the uterus but tilted or embedded | Uncommon, found during routine checks | Professional assessment, possible removal or replacement |
| Perforation | The IUD passes through the uterine wall | Rare, more likely soon after insertion | Urgent medical evaluation, ultrasound, possible removal by specialist |
| String detection | Feeling the strings with your finger after placement | Recommended monthly check | If strings are missing, contact your clinician for ultrasound or exam |
How IUD Placement Affects Risk of Falling Out
Immediate Post Insertion Checks
Right after an IUD is placed, your clinician will confirm the position using a speculum and feeling the strings. They will show you how to check your own strings monthly, so you notice if the IUD shifts. Expulsion is most likely in the first three months, often during menstruation when the uterus contracts.
Understanding the Anatomy of the Uterus
The size and shape of your uterus, how the IUD fits inside, and the strength of the cervix all influence stability. If your uterus is very large or the IUD sits too low, the device has a slightly higher chance of being expelled. Discuss any history of painful periods or uterine anomalies with your provider before insertion to lower risk.
Signs of IUD Expulsion or Partial Expulsion
Signs that your IUD may be falling out include longer strings, strings that feel softer, or strings that seem to have moved deeper. Some people notice the IUD itself at the cervix or feel it coming out. Cramping, heavier bleeding, or spotting that is unusual for you can also signal expulsion.
Not all string changes mean the IUD is coming out, but they should prompt a visit to your clinician for an ultrasound or exam. Ignoring these signs increases the risk of pregnancy or infection, so early evaluation is important.
IUD Effectiveness When Malpositioned
Pregnancy Risk and Protection Gap
If an IUD is expelled or significantly shifted, its contraceptive protection drops. Emergency contraception should be considered if you had unprotected sex after noticing the problem. Consistent use of condoms or another backup method is recommended until your clinician confirms the IUD is properly in place.
How Clinicians Check Position
Providers use a pelvic exam to feel the IUD strings, an ultrasound to see the device inside the uterine cavity, or sometimes an X ray if a perforation is suspected. If the IUD is only partially expelled, removal under guidance is usually advised to prevent embedding or infection.
Prevention and Correct Use Steps
- Learn how to check your IUD strings correctly after each period.
- Avoid pulling or cutting the strings too short to prevent accidental removal.
- Use a backup contraceptive method if you suspect expulsion.
- Schedule follow up visits and ultrasounds if your clinician recommends them.
- Report heavy bleeding, severe pain, or missing strings right away.
When to Seek Care and Next Steps
Quick medical attention for suspected expulsion, severe pain, heavy bleeding, or signs of infection protects your long term reproductive health. Partnering with your clinician ensures your method stays effective and comfortable over time.
FAQ
Reader questions
Can I feel my IUD if it is starting to fall out?
You may feel the IUD itself or increased cramping if it is moving, but many people notice only a change in the strings first. Checking strings monthly helps catch early signs.
What do I do if I see the IUD coming out but it is still attached?
Do not try to push it back in. Use backup contraception, avoid intercourse if possible, and contact your clinician immediately for removal or repositioning to reduce infection risk.
Will a partially expelled IUD still protect me from pregnancy?
Protection can drop significantly with partial expulsion, so assume the IUD is less effective and use condoms or another method until your provider confirms proper placement.
Can my IUD fall out after years in place?
While most expulsions happen early, rare late expulsions can occur, especially if there are uterine contractions or ongoing inflammation. Regular check ups and string awareness help catch this at any time.
