Frequently Asked Questions
Welcome to your umi brain boost. Whether you're brand new or just need some reassurance, we’ve got you. Let’s get into it.
Using Your umi Disc
Will it leak or spill?
As long as it’s tucked properly behind your pubic bone and emptied regularly, you’re all good. umi hugs your body to keep leaks at bay.
It might take a cycle or two to master, but you’ve got this.
How do I know if it's inserted correctly?
If you can’t feel it, you nailed it. No poking or pressure, just smooth comfort.
Check out our How to Use page for visual tips.
Can I sleep with it in?
Sleep easy. umi is safe and comfy to wear for up to 12 hours overnight.
Can I wear it while swimming or exercising?
Absolutely. Swim, run, stretch. umi’s with you through it all.
What if I don’t get it right straight away?
Totally normal! Most people need a few tries to find their groove. It’s a learning curve - we’ve all been there.
Fit & Flow
Will it fit me?
We designed umi to fit a wide range of bodies. If it takes a couple tries to feel just right, that’s okay. Your body + practice = perfect match.
Where is my cervix and why does it matter?
Your cervix is at the end of your vaginal canal and feels like the tip of your nose or lips.
It’s where your umi disc gently rests and collects blood.
We show you how to find it on our How to Use page.
If I have a heavy flow, will it work?
Yes! umi holds more than your average tampon or cup. Just empty it more often on heavier days.
How do I empty it during the day?
Over the toilet, gently hook it out, dump, rinse (or wipe), and reinsert. You can also use a pad or liner until you get the hang of it.
Will I need to change it in public toilets?
Maybe, it depends on your flow. umi can be worn up to 12 hours, but if you're still learning, plan ahead. Public toilet tip: bring a water bottle or use a tissue wipe if there's no sink.
Sex, IUDs & Safety
Can I have sex while wearing it?
You can, and it can be mess-free.
It's not a contraceptive and does not protect against sexually transmitted infections (STIs).
Some partners may feel it and others won’t. Just communicate and adjust if needed.
Can I use it if I have an IUD?
Yes. Just be gentle when inserting and removing your disc to avoid tugging on IUD strings. When in doubt, check with your doctor.
What if I feel discomfort or pressure?
It might not be tucked correctly. Try removing and reinserting, keeping the disc horizontal and relaxed.
Still uncomfortable? Reach out to a healthcare provider.
Is it harmful?
Not at all. umi is made from 100% medical-grade silicone.
It's BPA-free, latex-free and designed to be body-safe, but if you have a known silicone allergy or sensitivity, check with a healthcare provider before using.
Care & Cleaning
How do I clean my umi disc?
Before first use, sterilize in boiling water for 5–7 minutes.
During your cycle, rinse with warm water and gentle, unscented soap if needed.
At the end of each cycle, sterilize in boiling water for 5–7 minutes.
My disc is stained?
Staining is harmless and natural. You can sterilize your disk in boiling water or soak it in a mild sterilizing solution to freshen it up.
How long will one umi disc last?
Up to 5 years with proper care. Just check it regularly for tears, stickiness, or thinning.
Other Good-to-knows
What even is an umi disc?
It’s a flexible disc that collects your flow, not absorbs it. It sits near your cervix, behind your pubic bone so there is no suction needed.
How is it different from a tampon or cup?
Tampons and cups sit in the vaginal canal; umi sits further back. It doesn’t expand or use suction, and it can be worn during sex.
How old do I need to be to use it?
umi is designed for menstruating individuals, but we don’t recommend use under age 16 without guidance from a parent, guardian, or healthcare professional. If you’re unsure, talk to someone you trust or ask your doctor.
Can it get lost inside me?
Nope. The cervix is a small firm opening that won't let anything as large as a disc pass through.
If it feels out of reach, relax, give a gentle push with your pelvic muscles (like you're trying to poop a little), and use a finger to guide it out.
If you've had major pelvic or cervical surgery, or have any concerns, consult a healthcare provider.
