What Is a Menstrual Disc?
A menstrual disc is a reusable period product that sits higher in the vaginal canal, tucked behind the pubic bone and positioned in the vaginal fornix. Instead of absorbing menstrual fluid, it collects it.
Many people choose menstrual discs because they can be worn for up to 12 hours, may offer higher capacity than tampons, and can be reused for years with proper care.
Unlike menstrual cups, menstrual discs do not rely on suction to stay in place. This can make them a comfortable option for people who prefer suction-free period care.

The Main Difference: Size Choice
The biggest difference between Hey Zomi and my mimi is sizing.
my mimi comes in two sizes: Small and Large. Hey Zomi comes in one size.
This matters because menstrual disc fit is personal. A disc that works perfectly for one person may feel too large, too small or less secure for someone else.
Your ideal fit can depend on several factors, including:
- cervix height
- pelvic anatomy
- flow level
- age
- whether you have given birth vaginally
- personal comfort preference
- how active you are during your period
Hey Zomi’s one-size disc is 65 mm in diameter. That may suit some users well, especially if they already know that a mid-sized disc works for them.
my mimi gives users two options. The Small is 61 mm, while the Large is 68 mm. This gives you more flexibility when choosing a disc that suits your body.
If you are unsure which size to choose, you can read the my mimi menstrual disc size guide for a more detailed breakdown.
my mimi Small vs Hey Zomi
The my mimi Small is 61 mm in diameter and holds up to 32 mL.
It may suit people who:
- are new to menstrual discs
- prefer a smaller fit
- have a lower cervix
- have a light to moderate flow
- are under 30
- have not given birth vaginally
- feel nervous about trying a disc for the first time
Compared with Hey Zomi’s 65 mm disc, the my mimi Small offers a more compact option. For some users, this may feel less intimidating and easier to insert.
A smaller disc can also be helpful if you have previously found larger discs uncomfortable or difficult to position.
my mimi Large vs Hey Zomi
The my mimi Large is 68 mm in diameter and holds up to 61 mL.
It may suit people who:
- have a heavier flow
- want maximum capacity
- have a higher cervix
- are over 30
- have given birth vaginally
- want extra confidence overnight
- prefer a larger, more secure fit
Hey Zomi holds up to 52 mL, while the my mimi Large holds up to 61 mL. That makes my mimi Large the higher-capacity option in this comparison.
For people with heavier periods, longer workdays, travel days or overnight wear, that extra capacity may be an important consideration.
Capacity Comparison
Capacity is one of the main reasons people switch from tampons or pads to menstrual discs.
Here is how the two brands compare:
| Disc | Capacity |
|---|---|
| my mimi Small | 32 mL |
| Hey Zomi | 52 mL |
| my mimi Large | 61 mL |
For lighter days or first-time users, the my mimi Small may be enough. For heavier days, the my mimi Large offers the highest capacity.
Hey Zomi sits between the two my mimi sizes, which may suit users who are comfortable with a single mid-sized option.
Beginner Friendliness
If you are trying a menstrual disc for the first time, ease of use matters.
Many first-time users worry about insertion, positioning and removal. This is completely normal. Menstrual discs have a learning curve, especially if you are switching from pads or tampons.
my mimi is designed with beginners in mind. The soft silicone body makes it comfortable to fold, while the integrated loop tab helps make removal easier.
The two-size range also gives beginners a clearer starting point. If a 65 mm disc feels too large, my mimi Small offers a smaller 61 mm option. If you need more capacity or a larger fit, my mimi Large is available.
Hey Zomi also includes a removal loop, which may help with removal. However, because it comes in one size, users have less flexibility if that size does not suit their body.
For beginners who want more choice and a softer starting point, my mimi may be the easier option to try first.
Removal: Loop Tab vs Angled Removal Loop
Both my mimi and Hey Zomi include a removal aid, which is helpful because some traditional menstrual discs do not have a tab or grip.
my mimi has an integrated soft loop tab designed to support easier, more controlled removal.
Hey Zomi has an angled removal loop, also designed to make removal more accessible.
For many people, having any kind of removal aid can make a disc feel less intimidating. This is especially true if you are worried about reaching the disc or removing it comfortably.
The key difference is that my mimi combines its soft loop tab with two size options, giving users more control over both fit and removal.
Comfort and Fit
Comfort is one of the most important parts of choosing a menstrual disc.
A well-fitting disc should feel comfortable once inserted. You may be aware of it while learning how to use it, but it should not feel painful or distracting.
Because Hey Zomi is one size, it may work well for users who suit a 65 mm diameter. However, if you need something smaller or larger, there are no additional size options within the same product range.
my mimi offers a smaller 61 mm disc and a larger 68 mm disc. This means you can choose based on your body, flow and comfort preferences.
Having two sizes may be especially useful if:
- you have tried one-size discs before and they did not feel right
- you are not sure whether you need a smaller or larger fit
- your flow changes throughout your cycle
- you want a smaller disc for lighter days and a larger disc for heavier days
- you want more flexibility as you learn what works for your body
Firmness and Support
Firmness affects how a menstrual disc folds, inserts, opens and stays in place.
A very soft disc can feel comfortable, but some users may find it more difficult to guide into position. A disc with supportive structure can be easier to tuck behind the pubic bone and keep in place during movement.
my mimi is designed with a soft silicone body and a supportive double-edge rim. This gives the disc flexibility while still helping it maintain structure.
This can be helpful during:
- exercise
- walking
- running
- swimming
- long workdays
- travel
- overnight wear
Hey Zomi is also known as a soft menstrual disc. Some users may prefer that feel, while others may want more sizing choice or structure depending on their anatomy and activity level.
If you want a disc that feels soft but still has supportive structure, my mimi’s double-edge rim is a strong design feature.
Active Lifestyles and Exercise
A menstrual disc should move with your life.
Whether you are at work, at the gym, swimming, travelling, sleeping or running errands, you want a disc that feels secure and comfortable.
my mimi’s two-size range and supportive rim design can help users find a fit that suits their activity level. The disc is designed to sit tucked behind the pubic bone, helping it stay in position during everyday movement.
Hey Zomi may also suit active users if the one-size fit works well for their body.
The main advantage of my mimi is choice. If you find that one size does not suit your body during movement, having Small and Large options can make it easier to find a more secure fit.

Can You Wear Hey Zomi or my mimi Overnight?
Reusable menstrual discs are commonly worn overnight, depending on your flow and comfort.
my mimi can be worn for up to 12 hours. This makes it suitable for overnight use, lighter days, workdays and long stretches where changing a tampon or pad may be inconvenient.
Hey Zomi is also designed for extended wear.
As with any period product, your flow matters. If you have a very heavy period, you may need to empty your disc more frequently. The my mimi Large may be helpful for heavier days because it offers up to 61 mL capacity.
Can You Wear a Menstrual Disc During Sex?
One of the reasons many people choose menstrual discs is that they sit higher in the vaginal fornix.
Because of this positioning, menstrual discs can usually be worn during penetrative sex. This is different from menstrual cups, which sit lower in the vaginal canal and are not designed for sex.
Both my mimi and Hey Zomi are menstrual discs, so both may be suitable for period sex depending on personal comfort and fit.
Experience can vary from person to person. If something feels uncomfortable, stop and remove the disc.
Sustainability
Both my mimi and Hey Zomi offer reusable alternatives to disposable pads and tampons.
This is one of the biggest benefits of switching to a menstrual disc. Instead of using single-use period products every cycle, one reusable disc can last for years with proper care.
my mimi can be reused for up to five years. Over that time, it may replace hundreds of disposable pads or tampons, helping reduce period waste and saving money over the long term.
my mimi has also been recognised as Best Sustainable Period Care Solution in Australia by the Australian Health & Wellness Awards in both 2025 and 2026.
For customers looking for reusable period care with sustainability recognition, this is a meaningful point of difference.
Australian-Based Period Care Brands
Both Hey Zomi and my mimi are Australian-based brands, which makes them relevant options for Australian shoppers looking for reusable period care.
my mimi is designed and based in Australia, with a focus on beginner-friendly education, flexible sizing and reusable period products that fit into everyday life.
Hey Zomi is also Australian-based and offers a one-size menstrual disc option.
If supporting an Australian-based period care brand matters to you, both brands are worth considering. The bigger question is which design better suits your body.
Who Might Prefer Hey Zomi?
Hey Zomi may suit you if:
- you already know that a 65 mm disc works for your body
- you prefer a one-size option
- you like a soft menstrual disc
- you want an angled removal loop
- you do not feel you need multiple size choices
For some users, a one-size disc may be simple and convenient. If 65 mm is the right fit for your anatomy, Hey Zomi may work well.
Who Might Prefer my mimi?
my mimi may suit you if:
- you are new to menstrual discs
- you want two size options
- you want a smaller 61 mm disc option
- you want a larger 68 mm high-capacity option
- you have a heavier flow and want up to 61 mL capacity
- you want a soft loop tab for easier removal
- you want a soft disc with supportive rim structure
- you have an active lifestyle
- you want a reusable disc from an Australian-based brand
- you value sustainability award recognition
For many users, the biggest advantage of my mimi is flexibility. Instead of relying on one size, you can choose the disc that better suits your flow, anatomy and comfort preferences.
Hey Zomi vs my mimi: Which One Is Better?
There is no single menstrual disc that is best for every body.
The best disc for you depends on your anatomy, cervix height, flow, comfort preferences and how confident you feel using reusable period products.
Hey Zomi may be a good option if you want a one-size 65 mm disc and already know that size works for you.
my mimi may be a better choice if you want more size flexibility, a beginner-friendly design, a higher-capacity Large option and a soft integrated loop tab for removal.
The two-size range is especially helpful because menstrual discs are not one-size-fits-all for everyone. Having both Small and Large options gives you more control over your fit.
Final Verdict
Both Hey Zomi and my mimi offer reusable menstrual discs designed to make periods more comfortable, convenient and sustainable.
However, my mimi offers several key advantages for users who want more choice.
With two sizes, up to 61 mL capacity, a soft beginner-friendly design, supportive double-edge rim, integrated loop tab and sustainability award recognition, my mimi is a strong option for people looking for a reusable menstrual disc in Australia.
If you are new to discs, unsure about sizing, have a heavier flow or want a more personalised fit, my mimi may be the better choice.
