If your menstrual disc is leaking, it usually does not mean discs do not work for you. Most leaks come down to fit, placement, timing or learning how your body changes during your cycle.
The good news is that most menstrual disc leaks have a clear cause. Once you know what is happening, it becomes much easier to fix.
A menstrual disc usually leaks because it is not sitting in the right position, it has not been tucked securely behind the pubic bone, the size is not the best fit, or it is overflowing on a heavier day. Sometimes, what looks like leaking is leftover fluid in the vaginal canal after insertion or removal.
A menstrual disc works differently from a tampon or pad. It sits higher in the body, at the base of the cervix, and collects fluid rather than absorbing it.
The front rim should rest securely behind the pubic bone. When it is positioned correctly, it should feel comfortable, stay out of the way, and help reduce leaks.
If you are new to discs, read the how to use a menstrual disc guide before assuming something is wrong with the product itself.
This is one of the most common causes of leaking. If the front rim is not tucked up and back properly, the disc may sit too low and fluid can escape around the edge.
If your disc keeps leaking even when you insert it carefully, size could be the issue. A disc that is too small or too large may shift or sit incorrectly.
The my mimi menstrual disc comes in Small 32ml and Large 61ml.
Your cervix can sit higher or lower throughout your period. This means your disc may feel different from one day to the next.
If the disc is not sitting underneath or around the cervix properly, fluid may bypass it.
On heavier flow days, your disc may reach capacity sooner than expected. If leaking starts after several hours of wear, overflow may be the cause.
Some menstrual discs can self-empty when you use the toilet. This can happen when your pelvic muscles bear down and briefly shift the disc.
If the disc returns to position afterwards and does not keep leaking, it may be self-emptying rather than failing.
Sometimes what looks like leaking is residual blood left in the vaginal canal after insertion, emptying or repositioning.
If this is the cause, spotting usually settles quickly rather than continuing steadily.
Work through these checks before giving up. Most leaks improve with a few practical adjustments.
Leaks are more common while you are still learning, especially during:
Repeated leaking usually means the disc is not sitting in the right position or is not the best size for your body.
Ask yourself: am I tucking the rim fully, aiming it back, using the right size, and checking whether it is actually full?
These guides can help you check insertion, positioning and fit.

Yes. A small learning curve is common. Early leaks are often caused by placement or fit rather than the disc itself not working.
This can happen if the disc is sitting too low or is not tucked securely behind the pubic bone. Movement may reveal a positioning issue.
On heavier flow days, the disc may be reaching capacity sooner. Try emptying it more often and consider whether a larger size may suit you.
Yes. A poor fit can make the disc more likely to shift, sit incorrectly or feel less secure.
You can follow the my mimi insertion guide for step-by-step support.
