An intrauterine device (IUD) is a small, T-shaped contraceptive device placed directly into the uterus. This long-acting reversible contraception (LARC) offers effective birth control for several years, depending on its type. Regularly checking for your IUD strings is an important part of managing this birth control method, helping you stay informed about its position and continued function.
Why Check Your IUD Strings
Checking your IUD strings confirms the device remains in its proper location within the uterus. The presence and consistent length of these strings indicate the IUD is still in place and providing effective contraception. Your healthcare provider trims these thin threads during insertion, allowing them to extend slightly through the cervix into the top of the vagina. Any noticeable change in the strings, such as them feeling longer, shorter, or completely absent, could suggest the IUD has shifted or been expelled. Monitoring these indicators helps identify potential issues early, ensuring continued protection.
Step-by-Step Guide to Checking
To begin, thoroughly wash your hands with soap and water to prevent infection. Choose a comfortable position, such as squatting, sitting on the toilet, or lying down with your knees bent, to make locating your cervix easier. Gently insert your index or middle finger into your vagina until you can feel your cervix, which typically feels firm and rubbery, similar to the tip of your nose.
Once you have located your cervix, feel for the IUD strings. They usually feel like one or two thin, short pieces of fishing line emerging from the cervix. The strings are typically about 1 to 2 inches long and may soften and curl over time. You should only feel the strings themselves, not the hard plastic part of the IUD.
If you initially have difficulty finding the strings, try adjusting your position or checking at a different time, as the cervix can shift throughout your menstrual cycle. It is important to feel for the strings gently and avoid pulling on them, as this could accidentally dislodge the IUD. If the strings feel consistent in length and position each time you check, your IUD is likely in its correct placement.
When to Seek Medical Advice
Contact a healthcare provider if you are unable to feel your IUD strings when you previously could, or if they feel significantly longer or shorter than usual. These changes might indicate the IUD has moved out of its proper position or has been partially or fully expelled. Feeling the hard plastic of the IUD itself against your cervix or in your vagina also warrants immediate medical attention.
Consult a healthcare professional if you experience new or worsening symptoms such as persistent pain, severe cramping, unusual vaginal discharge, or fever. These symptoms could signal a complication, even if you can still feel your strings. If you suspect you might be pregnant or have concerns about your IUD’s effectiveness, consult your provider. Until your IUD’s position is confirmed, use a backup method of contraception. Never attempt to pull on or adjust your IUD or its strings yourself.
