How to Use
Your body.
Your disc.
Let’s get to know both.
You’ve got questions. (So did we.)
Where does it sit?
What if your cervix is high?
Will it leak?
We’re breaking it all down.
No shame, no pressure, just cycle confidence.
What even is an umi disc?
The umi disc is a soft, flexible menstrual disc that collects your flow rather than absorbing it. It sits at the base of your cervix and forms a seal to keep everything securely in place
Unlike a menstrual cup, the umi disc doesn’t rely on suction. It gently tucks behind your pubic bone, where your anatomy holds it naturally in position.
Getting to know your cervix
-
Where even is it?
Your cervix is a small, firm, donut-shaped opening at the end of your vaginal canal. It’s what your umi disc rests against.
-
Your disc’s landing pad
The umi disc sits just below your cervix and tucks behind your pubic bone. Your anatomy holds it in place so no suction is needed.
-
The finger test
With clean hands, gently insert a finger and feel for a small bump (it may feel like the tip of your nose.)
If your cervix is low, you’ll feel it with the first knuckle of your finger. If it’s high, just reach a little further. -
A few things to note
Your cervix moves and it’s usually lowest during your period (aka the best time to check). Feeling unsure is totally normal, but don't worry, we’re here for you.
How to insert your umi disc
Cleaning
-
Before First Use
- Sterilize your disc in boiling water for 5-7 minutes
- Let it cool and dry before use
-
During Your Cycle
- Rinse with warm water after each use
- You can use a mild, fragrance-free soap if you like
- Avoid antibacterial, scented or oil-based soaps
-
After Your Cycle
- Sterilise again in boiling water
- Store in a clean, breathable pouch (like your umi bag)
- Keep out of direct sunlight
Still got questions
What if I don’t get it right straight away?
That’s completely normal. It’s a learning curve and you're not alone.
Most people need a few tries or even a few cycles to get comfortable. You’ll learn what angle works best for your body. Be kind to yourself, we promise it gets easier.
How is it different from a tampon or cup?
Tampons absorb and your umi disc collects. That means no drying out and no strings.
Unlike cups, umi discs don’t rely on suction and sit higher up, behind your pubic bone and stay in place using your body’s natural anatomy.
Can I feel it when it’s in?
If it’s placed correctly, you won’t feel a thing. The disc tucks neatly behind your pubic bone and stays in place naturally.
If it presses on the cervix or feels uncomfortable, adjust it slightly. If irritation or discomfort continues, remove the disc and check with a healthcare professional.
How do I empty it during the day?
You can remove it, empty it into the toilet, give it a rinse (or wipe if you're out), and pop it back in.
Some users experience auto-dumping (when a bit empties itself while you're going to the toilet.) Totally normal. Your disc usually shifts back into place on its own, but you can always check and adjust.
Can I have sex while wearing it?
Yes! Unlike cups, the umi disc can be worn during penetrative vaginal sex. But everyone’s anatomy is different. Talk to your partner and check in with comfort. If it doesn’t feel right, take it out.
The umi disc is designed only for collecting menstrual fluid.
It is not a contraceptive and does not protect against pregnancy or sexually transmitted infections (STIs/STDs).
Always use appropriate protection if needed.
Tips & Tricks
- Try it in the shower. Warm water helps you relax and it’s an easy clean-up.
- Wear a pad or liner the first time if you're feeling unsure. Confidence builds with practice.
- Keep the disc level when removing. Horizontal movement helps reduce mess.
- Relax those pelvic muscles. Tension can make it harder to insert or remove. Deep breaths help.
- Your cervix should sit in the disc not beside it. That’s your “landing pad.”
- Use toilet paper when removing to catch any drips or “auto-dumps.”
- It won’t get stuck. Your disc can’t get lost inside you. Just bear down slightly and hook it out.
Safety & Care Info
Toxic Shock Syndrome (TSS)
TSS is a rare but serious infection linked to all internal period products - including menstrual discs, cups and tampons.
Symptoms may include sudden high fever, vomiting, rash, dizziness, or muscle aches.
If you experience any of these, remove your umi disc right away and seek medical attention.
12-Hour Rule
You can wear your umi disc for up to 12 hours at a time (perfect for long days or overnight.)
However, everyone’s flow is different. On heavier days, you might want to empty it sooner to stay comfortable and avoid leaking.
Never wear it for more than 12 continuous hours without removing and rinsing.
Allergy & Materials
Your umi disc is made from 100% medical-grade silicone and is completely free from latex, BPA, and phthalates.
If you have a known silicone allergy, do not use this product.
If you experience any unexpected irritation or reaction, discontinue use and consult a healthcare provider.
Age Guidance
umi is designed for menstruating individuals, but we don’t recommend use under age 18 without guidance from a parent, guardian, or healthcare professional. If you’re unsure, talk to someone you trust or ask your doctor.
Everyone’s body is different, and we want to make sure you feel confident and comfortable.
Replacement & Lifespan
Your umi disc is designed to last up to 5 years with proper care.
Check it regularly for any signs of wear (like tears, stickiness, or a cloudy surface.)
If you spot damage or the material feels off, it’s time to replace it.
Disposal
When your umi disc has reached the end of its life, just toss it in your regular household waste.
Never flush it. Your plumbing (and the planet) will thank you.
A Few Ground Rules
Let’s keep things simple, safe, and sanitary. Here’s the fine print (minus the fine):
Use only as directed. We’ve done the testing and taken the guesswork out of things - stick to the instructions, and you’re golden.
Postpartum & Infections. Do not use immediately after giving birth or while treating a vaginal infection.
This is a solo act. For hygiene reasons, your disc is for your use only. Sharing might be caring, but not when it comes to internal period products.
Not a medical device. Our disc is made from medical-grade materials and produced to high international standards - but it’s not classified or sold as a medical device.
Store it safely. After each cycle, pop it in a breathable pouch and keep it in a clean, dry place. Keep out of reach of children and curious pets.
If in doubt, check it out. Not sure if the disc is right for you? Had surgery recently? Experiencing unusual discomfort? Chat with your healthcare provider before using.
