why is my menstrual disc leaking? common causes & solutions
Experiencing leaks while using a menstrual disc can be frustrating, especially when you are expecting reliable, all-day protection. The reassuring news is that leaks are usually linked to positioning, fit, timing, or individual anatomy rather than a faulty product.
Whether you are new to menstrual discs or have been using one for some time, understanding why leaks happen can help you fix the issue quickly and confidently. Below, we explain the most common reasons a menstrual disc may leak and the practical steps you can take to prevent it.
incorrect positioning and placement
The most common cause of menstrual disc leaks is incorrect placement. A menstrual disc should sit high in the vaginal fornix, with the front rim securely tucked behind the pubic bone.
If the disc sits too low or is not fully tucked into place, it can shift during movement and allow fluid to escape. After insertion, gently check that the front rim is positioned behind the pubic bone. When placed correctly, the disc should feel comfortable and mostly unnoticeable.
overflow: understanding your flow and disc capacity
Every menstrual disc has a maximum capacity. On heavier flow days, the disc may fill more quickly than the recommended 12-hour wear time.
If leaks occur at predictable intervals, this often means the disc is full rather than incorrectly placed. Emptying the disc more frequently on heavy days can significantly reduce leaks and improve comfort.
weakened or incomplete seal
Although menstrual discs do not rely on suction, they still need to sit flush against the vaginal walls to work effectively. If the disc does not fully open after insertion or shifts out of position, leaks can occur.
If leaking happens, try removing and reinserting the disc, ensuring it fully unfolds and is guided back behind the pubic bone.
movement and pelvic muscle engagement
Activities that activate the pelvic floor muscles, such as exercise, coughing, laughing, or lifting, can sometimes cause the disc to move.
Some people find that gently checking or repositioning the disc after intense activity helps maintain a secure fit, particularly during the first few cycles of use.
tilted cervix and anatomical differences
Every body is different. A high, low, or tilted cervix can influence how a menstrual disc sits and performs.
If leaks continue despite correct insertion, experimenting with insertion angles or learning more about your cervix position may help. Understanding your anatomy can make a noticeable difference in both comfort and leak prevention.
choosing the right menstrual disc size
Fit matters. A disc that is too small may shift or overflow, while a disc that is too large can be harder to position correctly.
The my mimi menstrual disc is designed to provide a secure and comfortable fit. If leaks persist, reviewing sizing guidance and your individual needs can help determine whether a different size would suit you better.
tips to prevent leaks and improve comfort
- Ensure the disc fully opens after insertion.
- Confirm the front rim is tucked behind the pubic bone.
- Empty the disc more frequently on heavy flow days.
- Try different insertion angles if leaks persist.
- Recheck placement after exercise or prolonged movement.
when to replace your menstrual disc
A reusable menstrual disc can last for years with proper care. However, signs such as thinning silicone, loss of shape, or visible damage may affect performance and lead to leaks.
If your disc no longer holds its shape or feels noticeably different during use, replacing it can help restore reliable leak protection.
frequently asked questions about menstrual disc leaks
is leaking normal when first using a menstrual disc?
Light leaking is common during the first few cycles while you are learning correct placement. With practice, most users find leaks reduce significantly. Reviewing what a menstrual disc is can help clarify correct positioning.
does leaking mean my menstrual disc is the wrong size?
Not always. Leaks are often caused by placement or timing rather than size. If leaks continue despite correct insertion and regular emptying, sizing may be worth reviewing. Our guide on what size menstrual disc you should get can help.
can a full disc cause sudden leaks?
Yes. If the disc reaches capacity, it may leak even if positioned correctly. This is more common on heavy flow days and usually means the disc needs to be emptied sooner.
can stress or muscle tension affect leaks?
Yes. Pelvic floor tension can influence disc positioning. Reducing stress and staying relaxed during insertion can improve fit and comfort.
where can i learn more about correct insertion and removal?
Detailed guidance is available in our step-by-step resources, including how to remove a menstrual disc and other educational pages in our help centre.
