Understanding how to check IUD placement helps you confirm that your contraception is working correctly and reduces worry about unseen complications. This brief guide walks you through the key steps, signs, and clinical checks you can discuss with your clinician.
Use this structured overview alongside the details in each section so you know what to expect at each stage of checking IUD placement.
| Check Type | Who Performs It | When It Happens | What It Confirms |
|---|---|---|---|
| Self String Check | You | Monthly, at home | Feeling the strings through the cervix |
| Visual Cervical Check | Clinician | During any pelvic visit | Strings visible in the vaginal canal |
| Ultrasound Verification | Clinician | When needed or during follow-up | Exact IUD location and position |
| Pelvic Exam Palpation | Clinician | During a routine pelvic exam | Firm IUD base in the cervical canal |
| Emergency Check after Expulsion | Clinician | Immediately after symptoms | Whether IUD remains in place |
How to Do a Self String Check at Home
Feeling the IUD strings during a self check is the simplest way to monitor basic placement between visits. You will gently insert a clean finger into the vagina to locate a small, firm piece of thread that should hang a little below the cervix.
Keep in mind that it is normal for the strings to be shorter or harder to feel at certain times in your cycle, after insertion, or if you have a tilted uterus. If you cannot feel the strings or they feel significantly different than before, contact your clinician rather than assume the IUD has moved.
Schedule monthly self checks after your period ends, when the cervix is a bit lower and easier to reach, and always wash your hands before starting.
What a Clinician Checks During a Pelvic Exam
During a pelvic exam, a clinician uses a speculum to visualize the cervix and confirm that the IUD strings are present in the vagina and appear intact.
They will also gently palpate the IUD base through the cervix to ensure it feels firm and properly seated in the uterine cavity, which helps reduce the risk of partial or complete expulsion.
Clinicians may compare the string length and position to prior notes, noting any changes that could signal movement or partial expulsion of the device.
When an Ultrasound Is Used to Confirm IUD Position
An ultrasound becomes important when there is a suspicion of malposition, expulsion, or if the strings are not accessible during a pelvic exam.
Both transabdominal and transvaginal ultrasound can show the exact location of the IUD within the uterine cavity, helping clinicians decide whether the device can remain in place or needs adjustment or removal.
If the IUD appears embedded or perforated, an ultrasound guides further management and referral to a specialist when necessary.
Symptoms That Suggest Improper Placement or Expulsion
Persistent pain, unusual bleeding, or suddenly feeling the hard plastic of the IUD at the cervix can signal expulsion or malposition and require prompt evaluation.
Some people with a tilted uterus or significant uterine variation may have a higher chance of subtle movement, so reporting new symptoms early leads to quicker correction.
Regular self awareness combined with scheduled clinical follow up ensures that the IUD remains an effective, long acting contraceptive option for you.
Key Takeaways for Safe IUD Monitoring
- Learn the correct technique for a monthly self string check and do it after your period ends.
- Report any sudden pain, heavy bleeding, or loss of string sensation to your clinician right away.
- Expect a pelvic exam at routine visits to visually confirm strings and gently assess IUD position.
- Understand that an ultrasound is a safe, reliable tool to confirm placement if concerns arise.
- Keep regular follow up appointments so your IUD can be monitored for long term effectiveness and safety.
FAQ
Reader questions
How can I check my IUD placement at home between visits?
Perform a gentle self string check by washing your hands, relaxing, and inserting a clean finger into your vagina to feel for the IUD strings just below the cervix.
What should I do if I cannot feel the strings one month?
Contact your clinician for a pelvic exam or ultrasound, because the strings may be higher, shorter, or the IUD may have moved.
Can a pelvic exam alone confirm that my IUD is correctly placed?
A pelvic exam can show that the strings are present and the base is palpable, but an ultrasound may still be needed for full confirmation of position.
Will a tilted uterus affect how I check my IUD placement at home?
Yes, a tilted uterus can make strings harder to feel, so your clinician may rely more often on ultrasound or a longer speculum exam to verify placement.
