Mirena is an intrauterine device (IUD), a small, T-shaped contraceptive placed inside the uterus to prevent pregnancy. It releases a progestin hormone, providing highly effective birth control. Checking for Mirena threads is a simple yet important practice to confirm the IUD remains in its correct position. This regular self-check provides reassurance about its efficacy and helps identify potential issues early, contributing to peace of mind regarding contraception.
Preparing for Your Check
Before attempting to locate your Mirena threads, it is helpful to prepare appropriately. The optimal time for a self-check is typically at the end of your menstrual period, as the cervix naturally sits lower in the vaginal canal during this phase, making the threads more accessible. If you experience irregular periods or no periods with Mirena, establishing a consistent monthly schedule for checking, perhaps on a specific date, can be beneficial.
Prioritizing hygiene is important. Always wash your hands thoroughly with soap and water before beginning to minimize the risk of introducing bacteria into the vaginal area. Finding a comfortable and stable position can also significantly aid the process. Many individuals find it easiest to squat, sit on a toilet, or stand with one leg elevated, as these positions can help relax the pelvic floor and improve reach.
Locating the Threads
Once prepared, begin locating your Mirena threads by inserting a clean index or middle finger into your vagina. Gently guide your finger upwards until you feel your cervix, which is the firm, rounded opening at the top of the vaginal canal. It typically feels similar in consistency to the tip of your nose or a rubbery surface.
After identifying your cervix, carefully sweep your fingertip around its surface. You should be able to feel two thin, soft threads protruding slightly from the cervical opening. These threads are made of a fine, flexible plastic, often described as feeling like thin fishing line. The threads usually measure approximately 1 to 2 inches in length, extending just beyond the cervix into the upper part of the vagina.
It is important to feel for both threads, as their presence confirms the IUD is likely in place. The threads may sometimes curl up around the cervix or be tucked away, making them initially difficult to locate. When you find the threads, avoid pulling on them, as this action could inadvertently displace the IUD.
When to Contact Your Doctor
There are several situations where contacting a healthcare professional is advisable after checking your Mirena threads. If you are unable to feel the threads at all, or if they feel significantly shorter or longer than during previous checks, it could indicate that the IUD has shifted from its correct position. Another concerning sign is if you can feel the hard, plastic body of the IUD itself protruding from the cervix, as this suggests partial expulsion.
Beyond changes in thread sensation, certain physical symptoms warrant medical attention. These include experiencing new or worsening abdominal pain or cramping, particularly if it is severe or persistent. Unexpectedly heavy or prolonged vaginal bleeding, or a significant change in your typical bleeding pattern, can also be a sign of IUD displacement or another issue. Additional symptoms that necessitate immediate medical consultation include unusual vaginal discharge, fever, or chills, as these could signal an infection.
If you suspect pregnancy, even with an IUD in place, it is important to contact your doctor promptly. In any of these scenarios, it is recommended to use a backup method of contraception, such as condoms, and to avoid attempting to adjust or remove the IUD yourself.
