Your Questions Answered

It can be daunting trying something new and so we have collected a few of the most common questions asked here. If there's anything else you would like to know feel free to drop the two of us an email and ask:

Your Un Cup is Uncomplicated. It is a single piece of flexible, biocompatible, anti-microbial silicone. It works with your body rather than against it to collect rather than absorb your period. You wear it internally like a tampon while you’re sleeping, swimming playing sport or watching TV and you empty it when it’s convenient for you.

91% of woman that try a menstrual cup would recommend one to a friend. THAT’S HUGE. And why do women love them so much you may ask? Well, here are some of the top reasons:

Convenience - Your cup can capture far more than tampons or sanitary pads meaning you can fit it around your life! Cook with it, shop with it, play sports with it, swim with it, sleep with it and when it’s convenient for you to change it, change it.


Lower waste - An estimated 200,000 tonnes of sanitary waste ends up in landfill in the UK each year​ and this waste can take 500-800 years to decompose. Using a menstrual cup is one way to help you cut down the amount of single use plastic waste you create.

Health - Products that absorb rather than collect can soak up the natural discharge that helps to keep your body in sync. They also often contain nasty chemicals and various carcinogens which can be absorbed by your body. Menstrual cups on the other hand work with your body’s rhythm and are free from chemicals and other nasties.

No embarrassing odor - with cups you don’t have to worry about the risk of embarrassing odors as the menstrual fluid is not exposed to the air like it is with tampons or pads keeping you smelling like roses all cycle long.

The Un Cup is one of the only cups on the market that is made from anti-microbial, medical grade silicone. Its production processes, design and materials have all been fully certified by the French health ministry as being to the standards of a medical device and is certified ISO 13485.

Generic or cheaper cups are often unregulated and manufactured in the Far East. As a result the materials they are made from can become contaminated and contain traces of latex, phthalates, BPA and/or heavy metals. Over time these can be absorbed by your body and can cause swelling or irritation. Cups should always work out much cheaper than single use products and you’re going to have it for a long time, so we recommend getting the cup that makes you feel most comfortable with your health in the long run.


That’s for you to decide! At the moment we only sell one product as we’re just starting out but in the future we’d like to sell a wide range of options to make sure we’ve got you covered. At the end of the day it’s about what’s right for you and it doesn’t have to be all or nothing! Use a product that fits best with your cycle and your values. Cups are a great product and as long as you have no specific medical conditions ruling them out then odds are you’ll be pretty happy you made the change.

Every woman is different and there’s no one size fits all. Here’s a guide to sizing:

Size 1: Young women with a light flow who have not given birth will likely find this size easier to use. Equally, if you are an active sportswoman, you will likely be blessed with a strong perineum and so you would also be better off with this size.
Size 2: For you mums out there who have given birth vaginally we recommend this size which will likely be more suitable for the changes in your body. If you have a heavy flow you may well also find this size more convenient.


Before using your Un Cup for the first time (and at the end of each cycle), it's important to disinfect it. Disinfect your Un Cup by plunging it into a pot of boiling water for 7 minutes and allow it to cool. You’re now ready to rock. For helpful tips on getting started, take a look at our Best Practices page.

If your Un cups stem bothers you, you can absolutely cut it. If it doesn't bother you and you feel it's comfortable, you don’t need to. If you do fancy a stem cut, remove your  cup  and then cut the stem on a flat surface with a pair of clean scissors.

The Un Cup is inserted like a tampon. If you fold it correctly, you will have no trouble inserting it. If you suffer from vaginal dryness, we recommend you moisten it with water.

We recommend wearing your Un cup for 6 hours, however there are studies that show that menstrual cups can be used for longer than this.

There is a learning curve to trying anything new so don’t be put off if it takes a while to get fully comfortable with your new cup. Some women find that they are cup superstars from their first use whereas other women report it takes until their 2nd or 3rd cycle to get fully comfortable with their cup. In the end studies show that women generally find their cup more comfortable than single use alternatives but don’t get put off if it takes you a couple of uses to get there!

If you experience any discomfort while walking or while seated, or feel a pinching sensation in your vagina, you should trim your menstrual cup stem to the correct length for your vagina.

Take time to ensure a proper fit.

Trim the stem incrementally with clean scissors and reinsert your menstrual cup to ensure that the stem fits comfortably inside your vagina.

Studies have shown that cups are less likely to leak than tampons but in the case of leaking, reposition your menstrual cup one centimetre from the vaginal entrance.
Check the vacuum seal on your menstrual cup inside your vagina in two simple steps:
Slide one finger around your menstrual cup to ensure that it opened properly inside your vagina.

Pinch the base of your menstrual cup to rotate it inside your vagina.

Penetrative sex (penis-in-vagina sex, inserting sex toys, or fingering), is not recommended when using your Un cup. If you want to have penetrative sex on your period, just remove your cup and enjoy!

It is possible to moisten your Un cup with water or insert the cup in the shower which can help to ease the cup inside of you. Your Un cup is made of medical grade silicone, which is a porous material that can retain components of the lubricant that you may not want to have in prolonged contact with your vagina, and for this reason we do not recommend the use of silicone-based lubricants or oils.

We recommend that you seek advice from your gynaecologist or a health professional before wearing a menstrual cup with an IUD. If they suggest that it is safe to do so, be sure to break the suction seal and that the cup is loose before removing it.

Currently there only 2 cases of TSS with menstrual cups known in the world, which is much lower than the number of TSS related to tampons. Many studies are underway to better understand how this syndrome is triggered, but as a precautionary measure, we recommend that you do not wear your Un cup for more than 6 hours.
