FAQs: NÜDIE PERIOD CUP

The nüdie is made from hypoallergenic medical-grade silicone with a silky smooth finish for extra comfort.

Unlike other period cups with a rough stem, we created our own easy-to-hold Pebble™ pull for hassle-free removal. Plus, nüdie’s Tri-flow™ air release holes will keep you feeling fresh and protected, day or night.

Unlike tampons, pads and liners that absorb menstrual blood, period cups collect blood for internal menstrual protection. Once gently inserted, a period cup sits in the vagina and collects menstrual blood for up to 12 hours. Plus, it has a larger capacity than pads and tampons, allowing you to go about your day without frequent period product changes.

While all &SISTERS tampons and pads are made from 100% organic cotton, the nüdie is made from medical-grade silicone in three different sizes – making period cups the best option for women who suffer from heavy periods.

The nüdie period cup is made from the hypoallergenic medical-grade silicone. Medical-grade silicone is manufactured using clean-room technology, in completely sterile conditions.

Silicone is made by combining silicon (the earth’s second most abundant element, after oxygen) with tiny amounts of carbon and hydrogen – creating a hypoallergenic rubber-like material with low toxicity, high heat resistance and flexibility. Perfect for the nüdie!

The absorption capacity of a tampon is measured in grams (g), while the capacity of the period cup is measured in millilitres (ml). One g is equal to one ml.

Depending upon the size you choose (S-L), the nüdie has a capacity of 18–32 ml. That’s up to three times more than the tampon, which can absorb 6-18 g of menstrual blood.

We recommend that you don’t keep it in for longer than 12 hours.

The nüdie is available to buy on our website.

The nüdie is available in 3 sizes: Small, Medium and Large.

The Small is ideal for users under the age of 18. The diameter of the small is 38mm, the overall length including the pebble is 56mm and the overall capacity is 18ml.

The Medium is designed for women aged 18 to 30 who have not given birth vaginally. The diameter is 42mm, the overall length including the pebble is 61mm and the overall capacity is with a 24ml. If you have a light flow, the Medium is likely to be your best option. (Light flow is categorised by spotting or very light to light bleeding.) If you’re over 30 with a highly active lifestyle with strong pelvic floor muscles, this could be the best fit for you.

The Large is perfect if you have given birth vaginally or are over 30 years old. The diameter is 46mm, the overall length including the pebble is 66mm and the overall capacity is 32ml. However, if you’re over 30 with a highly active lifestyle with strong pelvic floor muscles, you may want to consider the medium.

We try to make sizing as straightforward as possible. However, if you run into any difficulties with your purchased size we are more than happy to exchange it for an alternate size.

The nüdie is made from the most flexible, hypoallergenic, medical-grade silicone available. Silicone can vary in its rigidity which is a huge factor in your comfort when using a period cup.

When we began this journey we tried, tested and felt a whole range of cups available on the market. This enabled us to create a cup with just the right level of resistance that is comfortable for majority of women. Our cups are soft yet robust, ensuring comfort and leak-free protection.

Our Large cup has slightly more rigidity than the Small and Medium cups, allowing for an easy release once inserted (ideal for those with weaker pelvic floor muscles).

We want all our customers to be 100% satisfied with their nüdie cup. It is an intimate relationship and one that we hope will last for years. If you think you’ve selected the wrong size, we are happy to offer free exchanges and returns (within 30 days). Simply contact us via email at [email protected].

You can use a period cup if you have an IUD/IUS, a contraceptive ring, or any other form of birth control. Please note that the nüdie is completely hormone-free and therefore does not provide contraceptive protection.

You can go to the toilet as you normally would while wearing your nüdie. After a bowel movement, you might want to check that the cup is still sitting properly. Take extra care to wash your hands thoroughly.

The nüdie is perfect for playing sports or undertaking fitness activities. The absence of a string is an added bonus for swimming on your period.

Using the nüdie whilst travelling is also ideal – it holds three times more blood than a tampon or pad, meaning less toilet stops along the way. Best of all, period cups are completely reusable, so you won’t ever run out or worry about disposing of used disposable period products.

Absolutely! Period cups are ideal for night, as they can be kept in for 12 hours. If you have a very heavy flow, you may want to use one of our organic cotton night-time pads for extra protection whilst you sleep.

Your nüdie may be leaking for a number of reasons. Most likely it’s because you didn’t insert quite right, and the cup wasn’t able to fully open and for suction to be formed between the rim and the sides of your vagina. The suction is how the cup prevents leaks, so use your finger to check if it is fully unfolded.

If you can feel the cup moving around, you likely need a larger size. If you find that the ‘Large’ size leaks, then pelvic floor exercises can help strengthen the surrounding pelvic floor muscles.

Other possibilities are that you’re using the wrong sized cup (too large or too small), or have an unusually positioned cervix. (see FAQ on cervix heights below)

Alternatively of course you may just have an exceptionally heavy flow day and left your nüdie in for too long!

We advise that you wait till your infection has cleared before using your nüdie. The nüdie does not absorb or interfere with the natural pH of your vagina, but in most instances you’ll need to allow your vaginal flora to restore before resuming use.

No. The nüdie does not absorb or interfere with the natural pH of your vagina. Thrush is caused by candida, a yeast-like fungus that can occur when the natural balance of your vagina is disturbed. Avoid using perfumed soaps to clean your cup and when washing your vaginal area as this can also disturb your pH balance.

Period cups are relatively easy to clean. There are three stages to keeping it bacteria and stain-free: daily cleaning, cleaning at the end of your period before storing for the next month, and the infrequent removal of stains.

There are several methods for daily cleaning. If you’re out in public, a paper tissue and a bottle of water is fine. You don’t technically need to clean your nüdie every time you empty it, so daily cleaning is based on your comfort. However, we do recommend that you give your cup a thorough rinse at least once a day. When travelling abroad, make sure you only use drinking water to clean your nüdie. Cleaning your nüdie well can help to hinder the build up of stains over time so as long as you look after it, it will look after you.

The cleaning agents mentioned below should be avoided as they’re not designed to be used internally and may compromise the condition of the nüdie:

  • Scented/ fragranced or anti-bacterial soaps
  • Vinegar
  • Tea-tree oil
  • Oil based soaps
  • Rubbing alcohol
  • Hand sanitiser
  • Pre-moistened wipes
  • Hydrogen peroxide
  • Dishwasher/ dishwashing detergent tablets
  • Other harsh chemicals

At the end of your period, we recommend that thoroughly sanitise your nüdie. Boiling is the most conventional way to sanitise your cup. This involves simply popping it in a pan of boiling hot water for 5 minutes. When boiling you can actually place it within a metal whisk (top tip!) to ensure it doesn’t come into contact with the bottom of the pan.

Sterilisation methods include baby bottle sterilisation tablets or fluids, such as Milton (a firm favourite amongst midwives and mothers). Their tablets and fluids are able to eradicate all bacterial, fungicidal and virucidal agents in 15 minutes. Other easy-to-use sterilisation methods include microwaveable sterilisation bags.

Try to avoid sterilising solutions with harsh chemicals or oils as these may cause disruption to the bacterial population of your vagina. Always check the ingredients of any product that is going to go inside your body. If you don’t feel comfortable with something, don’t use it.

We recommend that you avoid popping your cup in the dishwasher. Dishwasher detergent tablets contain chemicals that aren’t so vagina-friendly.

In addition to sterilisation make sure to clean the tri-flow holes with a (dedicated!) toothbrush to ensure that the cup is fresh and clean for your next cycle.

After disinfecting, dry and store your period cup in the specially designed cotton bag provided. The hypoallergenic and breathable material ensures an optimum environment for the cup, allowing any moisture to evaporate. Don’t store your cup in an airtight container as it needs ventilation.

Your nüdie may become a little stained after a number of uses. This is simply a result of the hormones and the chemical balance of each woman’s vaginal fluids. Don’t worry if your cup becomes a little discoloured, its effectiveness will not be compromised.

Periodically you may find that your cup is beginning to stain or become discoloured. Although staining will not affect the overall effectiveness of your cup, it probably doesn’t look so appealing! To freshen it up and remove the stains, we suggest soaking in a diluted vinegar solution – but please do take care to remove all traces of the vinegar, using your preferred sanitisation method, before re-using your cup. We do not recommend removing the stains on your cup more often than on a quarterly basis, as this can affect the quality of the silicone over time.

Depending on how well you take care of it, each nüdie period cup is made to last for up to 10 years. Some users prefer to change theirs more regularly, if discolouration becomes bothersome.

Checking the height of your cervix is important in choosing the right period cup. It can also help you to monitor your ovulation, fertility and sexual health. You should aim to check it several times a week over a month to get a good idea of the general height of your cervix. Your cervix does tend to change position during your cycle. When you are ovulating your cervix will be higher than normal and when you are menstruating your cervix will be lower than normal.

If you haven’t done this before we recommend doing this during a shower or a bath so you are clean and relaxed.

Insert your index finger into your vagina in an upwards direction towards your cervix which should feel similar to the tip of your nose. Note the position to which your finger is able to reach and use the knuckle rule to determine your overall cervical position.

A low cervix will measure up to the first finger joint. A medium cervix will measure up to the middle joint, roughly halfway up your finger and a high cervix will allow you to insert your finger all the way in before you reach your cervix.

If you have done this successfully, congratulations you now know the height of your cervix!

It depends how low your cervix is, if it’s really low and you can’t even reach your first finger joint then possibly not. This is fairly unusual and there are cups on the market that are better suited than the nüdie.

In most other instances, if you have a low to medium height cervix, you could drop a size, and go for our ‘Small’ and ‘Medium’ sizes, rather than the ‘Large’ which are appropriate for women with cervixes of all heights. If you are over 30 and have a low cervix we would encourage you to opt for our medium cup as it has a cup height which is likely to be a lot more comfortable for you. Don’t worry if you have a heavy flow, it simply means you may have to change once or twice more than you might otherwise, but we think that comfort is key!

Begin by creating a ‘U’ shape with your nüdie opening – press and hold the sides of your nüdie together, then fold it in half to create a ‘U’. Find a comfortable position and relax your pelvic floor muscles, then gently push the nüdie into the vagina with the tip approximately 1 cm into the vagina. The nüdie will now pop open inside your vagina and create a seal.

If you’re having difficulty inserting your nüdie, try wetting your cup with room temperature water, or using a bit of organic lubricant.

When removing the cup, always remember to use your own pelvic floor muscles. Push the cup down with your pelvic muscles until you can get a firm grip on our specially designed Pebble™ pull. Pinch the bottom with your forefinger and thumb to release the suction. Then keep pushing while slowly pulling the cup out. You can also rock it from side to side if necessary.

Don’t worry! It is impossible for the nüdie to become stuck or ‘lost’ in your body. Removing your period cup can be tricky at first, but we promise it will become second nature after a few attempts.

Pinch the bottom with your forefinger and thumb to release the suction. Then keep pushing while slowly pulling the cup out. You can also rock it from side to side if necessary.

If you are still having issues removing the cup, wash your hands thoroughly and try sliding your finger between the cup and vaginal wall, and bend your finger when you reach the rim. Be careful if you have long fingernails! Gently pull the stem of the cup downwards until you can reach and grip the base of the cup. Pinch the base to release the suction and remove gently.

While the nüdie cup can’t be recycled through domestic recycling facilities,  it can be recycled through industrial facilities. If your nüdie  is at the end of its 10-year lifespan or you just don’t need or want it anymore, then please do return it to us and we’ll ensure it’s safely recycled.
