A menstrual disc is a flexible, circular barrier designed to collect menstrual fluid internally, offering an alternative to traditional pads and tampons. Unlike a menstrual cup, which sits lower in the vaginal canal and relies on suction to stay in place, the disc is positioned much higher in the vaginal fornix, a wider space near the cervix. This distinct, high placement means the disc is held in position not by suction, but by the anatomical structure of the pelvis, specifically tucked behind the pubic bone. Understanding this unique positioning is paramount, as correct placement is what prevents leaks, ensures comfort, and maximizes the product’s effectiveness for up to 12 hours of wear.
Essential Steps for Correct Insertion
Successful insertion begins with preparation and finding a comfortable, relaxed position, such as squatting, sitting on the toilet, or standing with one leg elevated. Before handling the disc, always wash your hands thoroughly to maintain hygiene. The disc must then be folded to reduce its width, typically by pinching the circular rim in half to create a narrow, elongated shape, sometimes described as a figure-eight.
Once folded, the disc is inserted into the vaginal opening. Guide it downward and backward, following the natural angle of the vaginal canal toward the tailbone. Continue to push the disc horizontally and as far back as it will comfortably go, making sure the back rim passes the cervix. The disc needs to be fully past the cervix so that the base of the disc is positioned to collect the menstrual flow.
The Key Sign: Confirming Proper Placement
The definitive step to confirm correct placement is securing the front rim of the disc behind the pubic bone, which acts as the anchor for the device. The pubic bone is a firm, bony prominence felt just inside the vaginal opening, toward the front of the body. After pushing the disc back into the vaginal fornix, use a clean finger to gently sweep the front rim upward and inward until it hooks securely behind this bone.
This final tucking motion creates a stable seal and holds the disc in place. A disc that is seated correctly will be high up and should not be felt during normal activities like sitting, walking, or exercising. The most immediate sign of success is a complete absence of sensation; if you feel pressure or the disc’s presence, it is likely not tucked high enough. A proper tactile check reveals the front rim is firmly lodged against the pubic bone, and the disc is covering the cervix in the back.
Identifying and Fixing Common Misplacement Issues
If a menstrual disc is not placed correctly, the most common symptom is immediate or persistent leakage, indicating the disc is not fully covering the cervix or the front rim is unsecured. Leaking can also occur if the disc is sitting in front of the cervix rather than underneath and behind it, allowing flow to bypass the collection basin. Another sign of misplacement is a feeling of slippage or the disc moving out of position, which typically means the front rim has come untucked from the pubic bone.
If you notice these issues, a full removal and reinsertion is often unnecessary. Instead, try to re-tuck the front rim by squatting or gently bearing down, which can lower the disc slightly, making the rim easier to reach. Insert a clean finger and push the front edge upward and backward, ensuring you feel it snap or wedge securely behind the pubic bone. If discomfort, cramping, or pressure persists, this may suggest the disc is pushing against the cervix or is too large, requiring a full removal and a careful attempt at reinsertion to ensure the back rim is fully past the cervix.
Safe Removal and Cleaning Procedures
When the disc is ready for removal, first wash your hands thoroughly. To facilitate an easier removal, some users find that gently bearing down with their pelvic floor muscles can help nudge the disc lower and make the rim more accessible. This motion may also cause a small amount of blood to be released into the toilet, a phenomenon known as “auto-dumping,” which reduces the total volume inside the disc before removal.
To remove the disc, insert a finger and hook it underneath or over the front rim, then gently pull the disc out horizontally, keeping it level to prevent spillage. For reusable discs, cleaning involves emptying the contents, rinsing the device with cold water first to prevent staining, and then washing it with warm water and a mild, unscented soap. The disc should be sterilized at least once per cycle, typically by boiling it in water for five minutes before storing it for the next use.
