The discomfort of feeling a menstrual cup stem is common, especially for new users, but it rarely signals a significant problem. This sensation usually indicates a minor placement issue or an incompatibility between the cup’s length and internal anatomy. The stem is designed only as a guide to locate the cup’s base for removal, not as a string to pull. Ideally, the stem should sit completely inside the vaginal canal, and this issue is almost always fixable through simple adjustments or modification of the cup.
Identifying the Cause of Stem Discomfort
Stem irritation, such as poking or pinching, usually results from one of two primary issues related to internal geometry. The most frequent cause is that the cup is inserted too low, allowing the stem to sit right at or protrude from the vaginal opening. While cups are worn low beneath the cervix, if the base is easily reachable with a fingertip, the device is likely positioned too near the entrance.
Another common factor is a naturally low-sitting cervix, which shortens the functional length of the vaginal canal. The cervix often descends lower during menstruation, potentially pushing the cup down further than intended. If the cup is fully opened and sealed, its overall length, including the stem, may be too long for the available space, forcing the stem uncomfortably close to the exterior. To confirm this, gently tug the stem; if the cup resists moving downward, it has formed a proper seal, indicating the cup’s length is the issue.
Immediate Troubleshooting and Adjustments
Before making any permanent changes to the cup, first correct its position within the vaginal canal. When inserting the cup, aim it toward the tailbone, following the natural backward angle of the vagina, rather than straight up like a tampon. This angle helps the cup settle higher and seat correctly beneath the cervix, which often eliminates stem discomfort immediately.
If the cup is already inserted, attempt to re-seat it higher by gently rotating the cup 360 degrees. This rotation helps ensure the entire rim is open and sealed, encouraging the cup to slide further up the vaginal walls where the canal is typically wider. If a strong seal exists, break it by pinching the base, then re-insert the cup at a slightly different angle. Ensuring the cup is centered can also relieve irritation, as a crooked insertion may angle the stem toward a sensitive spot.
When and How to Trim the Stem
Trimming the stem is a permanent solution and should only be considered after attempting all positional adjustments across a couple of menstrual cycles. The stem’s sole purpose is to help locate the cup’s base for removal. Individuals with shorter vaginal canals may find removing the entire stem necessary for comfort. Never attempt to cut the stem while the cup is inserted, as this poses a significant risk of injury.
To safely trim the stem, remove and thoroughly clean the cup, along with a sharp pair of scissors, such as nail scissors. For stems with ridged rings, it is best to trim one ring at a time, reinserting the cup after each cut to test the fit and comfort. If the stem is a solid piece, remove a small section, perhaps half a centimeter, before retesting. After trimming, run a clean finger over the cut edge to ensure there are no sharp or jagged points that could irritate the sensitive tissues of the vaginal entrance.
