🩸 How to Pick the Right Menstrual Disc for Yourself & Choose the Correct Size

Choosing the right menstrual disc can feel confusing at first, but knowing a few key things about your body and flow can help you find the perfect fit for comfort and effectiveness.

1. Consider Your Menstrual Flow

  • Light to Medium Flow: Smaller or standard size discs often work well.

  • Heavy Flow: Look for larger capacity discs designed to hold more fluid. Some brands specify “regular” vs. “heavy” flow sizes.

2. Think About Your Anatomy

  • Vaginal Length: If you have a shorter vaginal canal, a smaller disc might fit better.

  • Cervix Height: Your cervix position changes during your cycle — it can be low, medium, or high. Knowing this helps:

    • A high cervix might mean you want a disc designed to sit higher up comfortably.

    • A low cervix might prefer a slightly smaller or more flexible disc.

3. Experience with Other Menstrual Products

  • If you’ve used tampons or cups: You might have an idea of what size and firmness feels best.

  • If new to internal products: Start with a smaller, softer disc to get comfortable.

4. Check Brand Size Guidelines

Different brands have different sizing systems, but most offer at least two sizes:

Size Typical Recommendation
Small / Regular Younger users, light flow, or those who haven’t given birth vaginally
Large Users with heavier flow, or who have given birth vaginally

5. Look for Flexible and Comfortable Materials

  • Most menstrual discs are made of medical-grade silicone — flexible and body-safe.

  • Some discs have firmer rims for easier insertion, while others prioritize softness for comfort.

6. Test and Adjust

  • It’s normal to try a couple of sizes or brands before finding your perfect match.

  • Many brands offer money-back guarantees or trial packs for this reason.

🛠️ How to Measure Your Cervix Height (Optional but Helpful)

You can check your cervix height to better understand what disc size might fit:

  1. Wash your hands thoroughly.

  2. Insert your middle or index finger into your vagina.

  3. Feel around to locate your cervix — it feels like a small round bump with a tiny dimple (the cervical opening).

  4. Note if it feels low (near your fingertip), medium, or high (you have to reach deeper).

Knowing this helps you pick a disc that sits comfortably near your cervix.

Final Tips

  • Always follow the instructions provided by the brand for insertion and removal.

  • If you experience discomfort, leaks, or difficulty removing, try a different size or brand.

  • Remember, menstrual discs are reusable in some cases — take good care of them for longevity and hygiene.
