Quick answer
If your menstrual disc won’t stay behind your pubic bone, it’s usually due to insertion angle, sizing, pelvic floor tension, or incomplete placement. Small adjustments to technique or choosing the correct size often resolves the issue.
Why won’t my menstrual disc stay behind my pubic bone?
If your menstrual disc, including the my mimi menstrual disc, isn’t staying securely behind your pubic bone, you’re not alone. This is one of the most common questions from first-time disc users.
The good news is that this issue is usually technique-related rather than a product fault. Below are the most common reasons a disc slips forward, and how to fix them.
Common reasons a menstrual disc won’t stay in place
-
Incorrect insertion angle
A menstrual disc should be inserted horizontally toward your tailbone, not straight up. Inserting vertically can prevent the rim from reaching the vaginal fornix, making it difficult to tuck securely behind the pubic bone. -
Size and fit issues
If your disc is too small, it may not stay anchored. If it’s too large, it may spring forward. Choosing the correct size is essential. Use the menstrual disc size guide to check which option suits your anatomy and life stage. -
High or changing cervix position
Cervix height can vary throughout your cycle. If you have a higher cervix, inserting the disc too high can make it harder to tuck behind the pubic bone. Guide the disc in gently, then press the front rim down and back to secure it. -
Incomplete placement behind the pubic bone
The front rim must be fully tucked behind the pubic bone. After insertion, use a clean finger to gently push the front edge upward and backward until it feels anchored. -
Pelvic floor muscle tension
Tension makes correct placement harder. Try inserting while squatting, sitting on the toilet, or with one leg raised. Relaxing your jaw and breathing slowly can also help relax the pelvic floor. -
Rushing the process
Especially in the first few cycles, discs require a bit of practice. Take your time. Small adjustments in angle or depth can make a big difference.
How to check if your disc is positioned correctly
- You shouldn’t feel the disc once it’s in place
- The front rim should feel tucked securely behind the pubic bone
- The disc should not slide forward when you stand or walk
