Frequently Asked Questions

Which Cup should I buy?

It’s worth remembering that we don’t recommend buying your cup based on your flow alone. Instead, sizing is based on fitness and age.


Hello Cups come in 3 sizes.


Our XS is our smallest, softest cup. It’s the perfect choice for teenagers, petite users or those who prefer a ‘mini’ tampon.


Our S/M is our ‘one size fits most’ menstrual cup. We recommend it for users under 35 – regardless of whether they have had children or not.


Our L (L for ‘Lovely’) is best for those over 35 who feel it’s a bit more roomy up there.


It’s worth noting that we find physically fit people are often best suited to the S/M regardless of age. If you’re uncertain, Hello Double Boxes are a great option to help you find which size works best for you. Many people find they can wear two sizes.

Yes we do! - The Hello Cup specifically designed for those with a low cervix launched in 2020 and has been a hit!

It has no toggle on the end which means it sits comfortably just inside the vagina entrance and doesn’t rum or irritate the user. The cup has grip rings at the base of the cup and also a small blob of TPE inside the base which gives you something to grip into to make removal easier.

It’s here!

We knew there was a need for a cute high cervix cup to add to our range for all those who really need the extra length in their cup!

We recommend measuring your cervix height on days 1-3 of your period so that you know what height of cup you need.

Cup basics

It’s time to put yourself and your body first. According to our fan(nie)s, Hello Cups are the world’s most comfortable menstrual cup. They’re made of top notch medical-grade TPE (thermoplastic elastomer). They are free of latex, silicone, perfumes, bleaches and all other nasties. We guarantee they will make having your period so much easier and cheaper. Unlike tampons which absorb your natural vjayjay moisture, your Hello Cup won’t dry you out or leave nasty bleached fibres behind.


Also, because you can reuse your Hello Cup for years – you won’t have to do that late night dash to the supermarket when your period shows up unexpectedly. No more rummaging around in your handbag for a tampon only to find it burst through its wrapper. No more stuffing tampons up your sleeve at work to hide the fact you’re off to the loo to change your tampon. Your Hello Cup holds three times more than tampons – making heavier days just that much easier.


Did we mention that you’ll save some serious cash along the way too?



While some people get the hang of them straight away, for others it may take a bit of practice – in the same way tampons take a bit of practice the first time around. Once you’ve got the hang of it you’ll find your Hello Cup is super easy to use! Sometimes first-time users like to try inserting it in the shower. The water helps with the lubrication and you don’t have to worry about any mess. New users can also use water-based lubricants if they feel they need to.


We recommend a shallow punchdown fold as the best fold for the Hello Cup. Once it is inserted, give your cup a gentle tug to help it form a seal. While you are getting used to it, don’t be afraid to move your finger around the base of the cup to feel for any indentations. Trust us, with a bit of practice, you’ll be a Hello Cup boss in no time.

We strongly recommend a shallow punchdown fold for Hello Cup. When we say ‘shallow’ , we mean it! Make sure the fold doesn’t go all the way to the bottom of the cup. To do a shallow punchdown fold you basically push a small indent into one side of the cup – push in then scoop it backwards. The shallower the fold, the easier you will find your Hello Cup opens. Try to make the bottom of your fold touch the bottom of the letters on the side of the cup. It can be fiddly to begin with, but it is worth it when you nail the insertion every time!

As long as your Hello Cup is the right size, is inserted correctly and emptied when needed, it shouldn’t leak. However, like tampons leaks can happen from time to time – especially if your cup hasn’t opened out properly. To check your Hello Cup is open, run your finger around the base of the cup. It should feel even right around. If you feel an indent, try twisting your cup around a couple of times. It also pays to give the toggle a couple of gentle tugs after inserting your Hello Cup to help ensure a suction has been formed. Don't forget, you can always take the cup out and try inserting it again! Some users chose to wear a liner as a safeguard while they get used to cup life, but most find cups to be far more reliable than tampons. If you feel you’ve done everything and your cup is still leaking – it may well be a sign it’s too big (if there’s not enough room for a cup to unfold it can stay folded), the ‘punch’ of your punchdown fold needs to be shallower or you need to tweak the angle you are inserting your cup on. Get in touch with us if you need some help!

Way less than you would have to with tampons – but everyone’s flow is different.

On heavy days you might need to empty your Hello Cup up to four times a day but later in your cycle you will likely find you only need to take it out once a day. It is not recommended you leave your Hello Cup in for more than 12 hours – ideally you should empty it every 8 hours. You can wear your Hello Cup overnight as well as while swimming and exercising.

It's easy to look after and clean your Hello Cup. Remember to wash your hands before you insert or remove your Hello Cup. After removing your Hello Cup, empty it and rinse under the tap with cold water. Cold water helps prevent stains from setting in. If you're not near a sink, it's fine to simply empty the contents of your cup into the loo, wipe your Hello Cup out with toilet paper and reinsert. Otherwise, you can clean it with water and a mild soap (just make sure all soap residue is rinsed off). While you can leave your Hello Cup in for up to 12 hours, we recommend changing it every 8 hours if you can. If you are traveling in countries where tap water is not safe to drink, we recommend rinsing your Hello Cup with bottled water or using our Hello Go sanitising cup and hand spray.


At the end of your period, wash and sterilise your cup before you put it away. We recommend popping your clean Hello Cup into a full pot of water which maintains a boil for at least for 3 minutes (use a timer so that it doesn't boil dry!) or soaking your Hello Cup in a glass of cold water containing 1/4 sterilising tablet (Milton is the most common brand and is available in supermarkets and pharmacies) for 15 minutes. Do not leave your cup soaking for longer than 30 minutes as this may damage the cup. Make sure your Hello Cup is fully dry before you store it.


Please be kind to your vagina and carefully consider that anything you put on your cup then comes into contact with a very sensitive part of your body. Household cleaners and sanitizers could harm your cup and your body. We recommend following the simple advice above!

While you can use a menstrual cup when you have an IUD, studies suggest there may be an increased risk of dislodging your IUD. It is a personal choice and we recommend that you talk to your doctor in advance. If you want to use your cup while your IUD is in, we recommend waiting three months after your IUD has been inserted (to allow it to settle in). It’s also a good idea to get your strings cut. Always make sure you break the suction fully before you start removing your cup.

Yes you can!

Hello Cups can be worn for up to 12 hours at a time so they are perfect for overnight.  

It can be a good idea to back your cup up overnight for the first few times to be sure that you have nailed the no leak life.

Yes you can!

Because your Hello Cup is worn internally and forms a seal, there is no way for the blood to escape. Woohoo!


With proper care your Hello Cup will last you around five years. There are no set rules around when you should replace your cup. If you want to do it once a year that is fine too.

Between uses store your cup in its organic cotton bag and / or somewhere out of direct sunlight. Make sure you wash your cup with a mild unscented soap, it won’t need scrubbing (and this may damage the surface).


How effective is Hello Go and will it protect against things such as coronavirus? Very effective. Our manufacturers, Zoono, have tested it against feline coronavirus (the recognised surrogate for COVID-19) and results showed it gave 99.99% protection. For more information see:


How does Hello Go work? Hello Go uses amazing technology from manufacturers, Zoono. Once dry, Hello Go resembles a layer of microscopic pins that attract, pierce and kill pathogens – the same principle as a pin popping a balloon. And in the same manner that the burst balloon cannot be reformed, neither can the pathogens – this means NO resistance and NO superbugs! Unlike traditional sanitisers that kill bacteria by poison or high alcohol content, Hello Go is a food safe, water-based surface sanitiser.


Is Hello Go okay to use internally? Yes, Zoono has a pH of 6.9, close to pH 7 which is neutral (water is classified as pH7). It won’t affect the pH balance in your vagina. Once dry it forms an antimicrobial layer and is bound to the surface, so it doesn’t leach and can be used with confidence.


Will Hello Go wash or rub off? No. Hello Go will remain active on the surface of your skin / cup for 24 hours. Normal washing of hands and drying with a towel will not affect efficacy. A single application of Hello Go will act like a glove, providing an invisible bond to the skin for 24 hours without the need for reapplication.


Should I apply Hello Go more than once a day? You don’t have to. It will remain active on the skin until natural exfoliation has occurred and this usually takes 24 hours or so (varies due to factors like perspiration). If you feel you want to apply more often that is fine too.


Will Hello Go discolour my clothes? No. Hello Go is a liquid that is invisible on application. It forms an antimicrobial barrier on the skin and will not stain clothing nor discolour skin.


Will Hello Go dry out my hands and cause chapped skin? No. Unlike other hand sanitisers that contain up to 70% alcohol and can chap the hands and dry the skin, Hello Go is mild but effective. On application, Hello Go will leave your hands soft and moisturised.


When Hello Go is applied to my hands will it allow the skin to function normally (eg. produce its own oil and sweat)? Yes. Hello GO does not inhibit the normal function of the skin. The antimicrobial layer produced by application of Hello Go bonds to the skin but is permeable to gases which allows the skin to “breathe” normally.


Has Hello Go been tested on a variety of skin types? Yes. It has been dermatologically tested in Germany on a range of skin types (older people, young people, fair skinned and dark-skinned people etc) – with zero reactions recorded.


How do you know Hello Go works? Hello Go’s manufacturer Zoono has done numerous successful tests with independent labs around the world to prove it is effective. The technology can also be proven with an ATP device which involves taking swabs (before and after treatment) from the surface and measuring the results. ATP is a globally accepted method of testing for pathogenic presence and is commonly used by QA personnel in all major food and beverage production facilities.


How do I use Hello GO? Spray your hands and / or cup and allow to dry. Easy peasy.


What’s the techy lowdown on Hello Go? Hello Go doesn’t use chemicals, poisons or alcohol to kill germs. Hello Go kills via a mechanical process. Hello Go leaves an invisible shield which resembles an antimicrobial spike or pin that pierces the microorganism, bursting it like a balloon. The shield carries on working. The active ingredient: <1% is a quaternary ammonium compound – these are commonly used antibacterial agents found in products such as toothpaste, contact lens products, cosmetics, soaps etc. This quaternary ammonium compound originates from sand. Pretty awesome, eh?


What are some fun facts I can entertain my friends with about Hello Go? Who doesn’t love a friend who is a fountain of knowledge?

Try these to score some points:

Hello Go is alcohol free, low-tox & dermatologically tested

Hello Go is less toxic than vitamin C & coffee

Hello Go is water-based (99% purified water!)

Hello Go is environmentally friendly

Hello Go surface products have food safety approvals in Australia and New Zealand

Hello Go is Australian and New Zealand owned

Hello Go is scientifically proven by over 100 independent lab reports

No, Hello Cups do not contain animal products and are not tested on animals.

In the interests of transparency, the medical grade material used (thermoplastic elastomer) is tested on animals in order to get the certification needed to prove it is medically safe for humans to put inside their body. Unless the manufacturer needs to change the formulation at some point, this process is not an on going one and none of the materials we buy from the manufacturer have been directly involved in animal testing.

The TPE material we make our cups from is recyclable. If you live in New Zealand or Australia and would like us to recycle your cup please sterilise it and send it back to us at The Hello Cup, Recycling Programme, 1 Marion Street, Wellington 6022. Please send us an email to let us know to expect the returning cup. When we receive your cup we will send you a voucher for a 50% discount off your next Hello Cup.

Hello Cups are the perfect travelling companion! We wish we’d known about cups when we were backpacking around the world! Not only will you have more money to spend but you'll have more room in your bags and you'll never be caught short no matter where in the world you are. Brilliant.

There is absolutely no reason teenagers can’t use cups. Users can start using Hello Cups from when they first get their period. We have plenty of teenage Hello Cups fans. Our XS Hello Cup is our smallest and softest cup and a great starting point for younger, first-time users. Some websites suggest menstrual cups may interfere with the hymen. Essentially inserting a cup is no different to inserting a tampon. The hymen will stretch and / or break naturally at some point, not necessarily during sex. Some people prefer not to use cups or tampons for personal or cultural reasons.

The risk of getting TSS (toxic shock syndrome) while using a menstrual cup is extremely low. TSS is a rare but serious condition caused by toxins released by the bacteria Staphylococcus aureus. Symptoms include fever, chills, dizziness, fatigue, muscle aches, or rash. If you experience any of these symptoms – remove your Hello Cup and seek medical advice. To keep yourself safe, ensure you do not leave your cup in for more than 12 hours. TSS can only occur if the toxin enters your bloodstream. This can happen if you have an abrasion – which could be caused by sex, nails, tampons or cups being inserted without sufficient vaginal lubrication. If you are aware you have an abrasion, avoid wearing your cup (or tampon) until it has healed. Wash your hands before and after changing your cup. If you have access to a sink, you can wash your cup after each use with hot water and mild soap. If you are in a loo with no hand basin – it is fine to simply wipe out your cup and reinsert. It is important to sterilise your cup at the end of your cycle. If you have two cups you may wish to alternate them and sterilise after each use. To sterilise your cup, boil in for three minutes, sterilise in the microwave (as you would a baby bottle – specific times and settings will depend on your microwave) or use a sterilising tablet. Sterilising tablets are a great option if you are in shared accomodation. Just soak your menstrual cup with 1/4 of a sterilisation tablet in a glass of water for 15 minutes. Sterilisation tablets (a common brand is Milton) can be found in most supermarkets and chemists (normally in the baby section). If you have any questions email

Trouble shooting

Springing a leak is no fun. But, like with tampons, they can happen from time to time. Here are our pro-tips on how to resolve them:

1. Your cup hasn’t opened out properly. This is normally caused by either the fold or the size being not right.

We recommend using a shallow punchdown fold rather than the ‘c’ fold when inserting your cup, angling it back toward your tailbone. Let the cup open when it is just inside the vagina and then manoeuvre higher with the toggle. It also pays to give the toggle a couple of gentle tugs after inserting your Hello Cup to help ensure a suction has been formed.

Despite what many think, a leaking cup can sometimes be a sign your cup is too big. If your cup doesn’t have enough room to unfold properly, it may buckle and you might experience leaking down the side. Fit and petite users often find they are a smaller size regardless of age and whether or not they have had children. We do not recommend choosing a cup size based solely on your flow. Our handy size quiz will help you work out what’s the best choice for you.

2. Your cup isn’t sitting under your cervix.

Ideally you need your cup to sit just below your cervix but here’s the catch - not all cervixes are centred! Next time you have a smear or vaginal exam, ask your doctor or gynaecologist where your cervix sits. If your cervix sits to the left, for example, you will want to angle your cup more to the left to ensure it sits below your cervix.

3. Your cup was wet when you inserted it.

If there’s excess water on the outside of the cup it can mix with menstrual blood already in your vagina making you think you’ve sprung a leak when it is more of an ‘existing situation’ scenario. To avoid this, wipe your cup dry before you insert.

4. If your bowel is full, it can affect your cup (your mum says hi and to eat more fibre).

Similarly when you do a poo, the motion can sometimes cause a bit of leakage.

5. If your cup is nearly full, the weight of the cup can reduce the suction which may cause leakage.

While cups can be worn for up to 12 hours, if your flow is heavy you will need to empty more often.

6. Your cervix height can complicate things too! If you have a high or low cervix it may prevent the cup from opening fully. You can use our handy guide to measure your cervix and check to see what is happening for you!

...Be patient with yourself. Cups can take a while to get the hang of - but don’t give up! Some users chose to wear our washable Hello Liners as a safeguard while they get used to cup life.

No - if your cup is inserted correctly, a seal will have formed and this will prevent your cup from leaking. Because they hold more blood than tampons, your Hello Cup is perfect for overnight.

Unlike tampons and pads, the blood doesn’t mix with the air. It is this combo that can make having your period literally a stink time. Cups are pretty much odour free. Yay. If you do find your cup a bit wiffy, try changing it more regularly. Here are a few other tips to combat odour:

  • Dry your cup in indirect sunlight for a few hours
  • Boil your cup for three minutes (like you do at the end of each cycle)
  • Soak your cup in a mix of lemon juice and water or a 1/2 & 1/2 white vinegar and water solution for an hour - then rinse thoroughly.

Using a Hello Cup is very clean because blood is captured inside the cup. While you're getting the hang of things and nailing your technique, you might find it's a bit messy - but not messy like a scene from the Texas Chainsaw Massacre. To remove the cup, locate the base and squeeze it gently. This will release the suction. Pull the cup out keeping it upright. Simply tip the contents down the toilet, rinse or wipe out the cup and reinsert. Simple.

Stains can happen and vary between individuals. The best way to prevent staining is to rinse your cup in cold water each time you remove, making sure you flush out the suction holes and also rinse the base and around the lettering on the cup. Cold water halts stains setting in - whereas hot water can help them set in - so remember - cold always comes first! If you have existing staining, you can soak your cup in a 1:3 solution of household bleach and water (1 part bleach to 3 parts water) for 15 - 20 mins. Don't leave your cup in the solution for longer than the recommended time frame. A mixture of lemon juice and water (50/50) or white vinegar and water (50/50) can also help lift stains.

Very occasionally. Usually the user has a high cervix and wasn’t aware. We recommend measuring your cervix on days 1-3 of your period using our handy guideso you know which cup to buy.

If your cup does get stuck - don't panic - it's basically a dead end street up there and your Hello Cup has just moved up a little higher. During the course of a day your cervix can move up and down and your cup can move up and down with it. If you can't feel the toggle of your Hello Cup, the best thing to do is to sit on the loo, breathe deeply and then bear down and push using your pelvic floor muscles - a bit like you are doing a poo. Too much info? We're all friends though, right? This will help your cup to move down and you should now be able to reach it. While it's easier said than done sometimes, the key is to relax - the more tense you are, the more your muscles will clench around your Hello Cup making it harder to remove your cup. The more you use your menstrual cup, the easier and faster removal will be. If you are still having issues, drop us a line
