Quick answer
A leaking menstrual disc usually means it isn't tucked behind the pubic bone or hasn't formed a proper seal. For Flex Disc users, the fix is often a simple adjustment in angle or insertion depth. Try repositioning higher and further back, then check the seal by doing a gentle kegel or squat.
Flex Disc
Most Common Causes of Leaks
Leaks happen when the disc sits too low in the vaginal canal or isn't fully open. The disc must sit in the vaginal fornix, behind the pubic bone, to stay in place and catch fluid. If you feel the disc's rim near the opening, it's not deep enough.
Another cause is incomplete unfolding. When the disc doesn't fully open after insertion, it can't create a seal. This is more common with softer discs. Gently rotating or pressing on the rim after insertion helps it pop open.
Step-by-Step Leak Fixes
Start by washing your hands and getting into a comfortable position—squatting or sitting on the toilet works well. Insert the disc by pinching it flat and aiming it toward your lower back, not straight up. Push it until you feel resistance from the pubic bone, then tuck the front rim behind it.
After insertion, do a quick seal check: bear down or squat. If you feel the disc shift or see fluid, it's not in place. Remove and try again. If you have heavy flow, empty the disc more frequently—every 4-6 hours instead of 12—to prevent overflow.
When to Consider a Different Product
If you've tried multiple adjustments and still experience leaks, your anatomy may not be suited for a one-size disc. Some people have a low cervix or narrow fornix that makes a good seal difficult. In that case, a smaller disc or a different period product might work better.
Flex Disc Annual Supply offers a full year of discs in one shipment, so you can practice without worrying about running out. If leaks persist after a few cycles, it's worth exploring reusable options or consulting a healthcare provider.
Leak diagnosis at a glance
- Symptom: Fluid leaks soon after insertion or during movement. Likely placement issue.
- Likely cause: Disc not tucked behind the pubic bone or not fully opened. Check depth and rotation.
- Corrective action: Remove, reinsert aiming toward lower back, tuck rim behind pubic bone, and do a seal check. Try this for 2-3 cycles.
