"The average person has more than 450 periods in their lifetime. That’s over 3,000 days of bleeding!"

So when your menstrual disc pops out unexpectedly, it’s more than just annoying - it can throw off your whole day or night. But don’t worry! If this has happened to you, you’re not alone. It’s actually one of the most common questions we hear from the my mimi community. And the good news? It’s usually an easy fix.

Whether you're new to menstrual discs or just switched brands, this guide will help you understand why it happens - and what you can do about it.

common reasons why menstrual discs pop out

your menstrual disc isn’t tucked behind the pubic bone

This is the most common cause. Menstrual discs stay in place by tucking behind the pubic bone, not through suction like cups. If your disc isn’t secured properly, it can shift or slide forward when you move.

How to fix it: After inserting your disc, use a clean finger to push the front rim up and back towards your tailbone. You should feel it "catch" securely behind your bone.

your menstrual disc isn’t inserted deep enough

If your disc is sitting too shallow, it won’t properly collect flow or stay secure. This often happens when users are nervous or hesitant during insertion.

Tip: Insert your menstrual disc at a downward angle towards your lower back for a deeper, more secure fit. Learn more about how to insert a menstrual disc for beginners.

the firmness of your menstrual disc matters

A disc that’s too soft might collapse inside, while a disc that’s too firm might not flex enough to stay tucked. The right firmness helps it stay secure without discomfort.

Helpful hint: The my mimi menstrual disc offers balanced firmness for better security and comfort. If your current disc keeps sliding out, you might need a firmer design like the best menstrual disc in Australia.

pelvic floor pressure can shift your menstrual disc

Strong pelvic floor muscles, coughing, sneezing, laughing, or lifting heavy objects can all apply pressure and dislodge your disc.

Quick test: Try inserting the disc while lying down and focusing on breathing out to relax your pelvic muscles. This can improve placement and security.

how to keep your menstrual disc in place

find the best position for inserting your menstrual disc

Standing with one leg up might not work for everyone. You could try inserting while:

• Sitting on the toilet
• Squatting in the shower
• Lying flat on your back with your knees bent

use a little water-based lubricant for easier insertion

Dry insertions can cause folding issues. Using a small amount of water-based lubricant (only on the rim) can help your menstrual disc slide into position more easily.

know your cervix position

Your cervix changes position during your cycle. A low cervix can make some discs harder to place securely. Choosing the right size and style matters. Check out how to choose the right menstrual disc size.

try different folding techniques

Experiment with the taco fold, or half-fold to improve control during insertion. Some users also find pushing the back rim into place first works best before tucking the front behind the pubic bone.

when a menstrual disc popping out could signal another issue

If you’ve tried everything and your disc still will not stay put, it might be worth checking:

• Pelvic organ prolapse: A health professional or pelvic floor physiotherapist can assess this.
• Very low cervix: You may need a different disc size or shape.
• Postpartum changes: Your anatomy might still be adjusting after birth.

For persistent concerns, always consult a medical professional. my mimi discs are designed for a wide range of body types, but sometimes individual needs vary.
