Why is my menstrual cup leaking? 9 common causes and easy fixes
If you’re dealing with surprise stains and emergency bathroom runs, don’t lose hope. Leaks are common, especially when you’re new to cups, and they’re usually fixable with a few smart tweaks.
Let’s troubleshoot your cup game.
1. You might be using the wrong size
Lunette offers two sizes:
- Size 1: For light to moderate flow
- Size 2: For moderate to heavy flow
If you’re using size 1 and bleeding through it quickly, it might be time to size up. Size 2 holds more fluid and is slightly firmer, which helps it stay in place better during heavier days.
2. Your cup is full - empty it more often
While menstrual cups can be worn for up to 12 hours, that’s not a one-size-fits-all rule. If you have a heavier flow, try emptying your cup every 4–6 hours. If it’s ¾ full when you remove it, it’s time to adjust your schedule.
3. Your cervix placement matters
Your cervix can shift during your cycle. If your cup sits too high or off-center, blood may bypass it. Here’s what to do:
- Locate your cervix (it feels like the tip of your nose - soft and squishy)
- Insert your cup below the cervix, not next to it
- If you have a low cervix, consider trimming the stem for comfort
- Tilt your pelvis slightly during insertion to align the cup properly
4. Your cup isn’t fully open
If your cup doesn’t pop open completely, it won’t seal properly. After inserting:
- Rotate the cup gently
- Run a finger around the rim to check for folds or dents
- Try the punch-down fold or triangle fold if the C-fold isn’t working
5. Try squatting during insertion
Standing straight can make insertion tricky. Squatting over the toilet or in the shower tilts your pelvis, helping the cup slide in and open more easily.
6. Bowel movements can shift your cup
Pooping can push your cup downward especially if you have strong pelvic floor muscles. Don’t worry, it won’t fall out. Just wash your hands and gently push it back into place afterward.
7. Clean the air holes
Those tiny holes near the rim? They’re crucial for suction. If they’re clogged, your cup won’t seal properly. Use a soft brush or pin to clean them during each rinse.
8. Your pelvic floor might need a workout
Weak pelvic muscles can make it hard for your cup to stay snug. If you notice leaks when standing up or moving, try Kegel exercises to strengthen your pelvic floor. Bonus: they help with bladder control too.
9. Your cup might not be the right fit
If you’ve tried everything and still experience leaks, your cup’s shape or firmness might not suit your anatomy. Everyone’s body is different. Consider trying a different size or style or explore period panties as an alternative.
Leaks happen, but they’re not a dealbreaker. With a little troubleshooting, you’ll be a menstrual cup pro in no time. And if you’ve found a tip that works wonders for you, share it! We’re all about supporting each other on this leak-free journey.
