An intrauterine device (IUD) is a highly effective, long-acting, reversible form of birth control. Understanding how to check for proper IUD positioning and recognizing signs of potential movement can provide reassurance and help ensure continued effectiveness.
Checking for IUD Placement
The primary method to check IUD placement involves feeling for its strings. These thin, soft threads, often described as feeling like fishing line, extend a few centimeters into the vagina from the cervix. They are attached to the IUD, which sits inside the uterus.
To perform this check, thoroughly wash your hands with soap and water. Find a comfortable position, such as squatting or sitting, to make it easier to reach your cervix. Gently insert your index or middle finger into your vagina until you feel your cervix, which has a firm, rubbery texture similar to the tip of your nose.
Once you locate your cervix, gently sweep your finger around its opening to feel for the IUD strings. You should feel one or two strings hanging down. If the strings are present and their length feels consistent with what you typically feel, your IUD is likely in its correct position and providing contraception.
Other Indicators of IUD Movement
While checking for IUD strings is the primary method to assess placement, other physical signs can indicate potential movement. Unusual or severe pain and cramping, which might be sharp, sudden, or persistent and not relieved by over-the-counter pain medication, can signal the IUD has shifted or is being expelled.
Changes in bleeding patterns also indicate IUD displacement. These include irregular vaginal bleeding, heavier or longer periods, or spotting between periods. With a copper IUD, a return to lighter-than-usual menstruation might suggest movement.
You might feel the hard, plastic part of the IUD protruding from the cervix or within the vagina, where normally only the strings are palpable. A partner might also report feeling the IUD during sexual intercourse. Unusual vaginal discharge or pain during sexual activity could also be symptoms.
Steps to Take If You Suspect Movement
If you suspect your IUD has moved based on string changes or other symptoms, contact your healthcare provider immediately. Do not try to adjust or remove the IUD yourself, as this can further dislodge the device or cause injury. Tugging on the strings could worsen the situation.
While waiting for your appointment, use a backup method of birth control, such as condoms, if you engage in sexual activity. A displaced IUD may not be effective at preventing pregnancy. Your healthcare provider can confirm the IUD’s position through a pelvic examination, ultrasound, or X-ray.
