Why Does My Menstrual Disc Keep Untucking? Troubleshooting Tips for a Secure Fit

Using a menstrual disc can be a game-changer for many, offering comfort and up to 12 hours of leak-free protection. But if your disc keeps “untucking” (shifting out of place or leaking), it can be frustrating and uncomfortable.

Don’t worry — you’re not alone! Here’s why it happens and how you can fix it.

🧠 What Does “Untucking” Mean?

When we say a menstrual disc is “untucking,” it means the disc has shifted from its proper position, usually sliding forward or downward, which can cause leaks or discomfort.

The disc is designed to tuck snugly behind your pubic bone and form a seal around the cervix. If it moves out of place, it won’t hold fluid properly.

🔍 Common Reasons Your Menstrual Disc Keeps Untucking

1. Incorrect Insertion Angle

  • Menstrual discs need to be inserted with the right angle — typically flat and slightly tilted toward your tailbone, not straight up.

  • Inserting it too shallow or at the wrong angle can cause it to slip out.

2. Not Fully Seated Behind the Pubic Bone

  • The disc must sit firmly behind your pubic bone to stay in place.

  • If it’s too far forward or not pushed back enough, it can untuck easily.

3. Disc Size Doesn’t Fit Your Anatomy

  • Menstrual discs come in different sizes or firmness levels.

  • A disc that’s too small or too flexible may not stay put.

  • Conversely, a disc that’s too large might be uncomfortable and prone to shifting.

4. Physical Activity or Movement

  • Excessive bending, stretching, or high-impact exercise might cause the disc to move.

  • Sitting or squatting incorrectly can also shift the disc out of place.

5. Emptying Too Late or Not Often Enough

  • Overfilled discs are more likely to slip because the weight pushes it downward.

  • Empty your disc every 8–12 hours or sooner if needed.

💡 Tips to Keep Your Menstrual Disc Secure and Comfortable

✔️ 1. Practice Proper Insertion

  • Fold the disc (usually a “push-down” fold or “C” fold).

  • Insert it flat, angled slightly back toward your tailbone.

  • Use a finger to gently push the disc behind your pubic bone until you feel it “pop” into place.

✔️ 2. Experiment With Size and Firmness

  • Try different brands or sizes if your disc keeps slipping.

  • Firmer discs may stay put better but can be less comfortable; softer discs are comfy but may shift more.

✔️ 3. Check Your Positioning

  • After insertion, gently pull on the rim to check that the disc is secure.

  • If it moves easily, try repositioning it.

✔️ 4. Empty Regularly

  • Don’t wait until the disc is full—empty it every 8–12 hours to reduce pressure.

✔️ 5. Avoid Excessive Movement Right After Insertion

  • Give yourself a few minutes after insertion before vigorous activity.

  • Practice walking, sitting, and bending to get used to how it feels.

🔄 When to Seek Help or Consider Alternatives

  • If you consistently struggle with leaks or untucking despite trying different sizes and insertion techniques, you might want to:

    • Consult a healthcare provider to check for anatomical issues.

    • Try switching to a menstrual cup or period underwear.
