The general recommendation concerning sizes and menstrual cups is usually that if you are under 30 and have not given birth, you should choose the smaller size. And if you are over 30 and have given birth, then you should choose the larger menstrual cup. We at Flowcup know that women’s genitals are very individual, that we bleed different amounts and have varying degrees of genital sensitivity. Therefore, it is our recommendation that you choose a menstrual cup based primarily on how heavy your periods are. If you are unsure which size would suit you, then we recommend choosing the smaller size, as the menstrual cup holds almost four times as much menstrual fluid as a tampon.


Defer using the menstrual cup until you feel your body and genitals have healed properly after your delivery.


Your Flowcup will be delivered as a regular letter with the postal service. Your kit will usually be delivered through your letter box. If the Flowcup has not been delivered due to the incorrect address being provided by the customer, that is the customer’s responsibility.

The customer pays to return items unless the Flowcup is damaged or we have sent you the wrong item. Returns should be sent as a letter and not via “collect on delivery”. Once you have exercised your right of withdrawal, please return the unopened envelope to us. Please contact us if you require further help.

We have chosen to endeavour, to the fullest extent possible, towards becoming a so-called Zero Waste company, quite simply because we want to conserve our environment. We have spoken to many women and girls who feel that product packaging and manuals often end up in the bin. Your manual can be found online here: You can always carry the manual around with you in your mobile. We believe that the best manual is one that is always readily available.

It’s entirely natural to be sceptical about testing a menstrual cup for the first time; it can feel like a big step. Our surveys show that 9 out of 10 women who try a menstrual cup are satisfied and choose the cup instead of pads or tampons. These statistics strongly suggest that you will also be satisfied.

You can use Flowcup whether you have had sex or not. You know your body best. If you use tampons you should be able to use a menstrual cup.

Always sterilise your menstrual cup before you use it for the first time and before each menstrual period. Boil your menstrual cup in a saucepan with water for five minutes or use the sterilisation bag with 100ml of water and microwave it at 750 watts for three minutes.

Yes. If you follow the manual and handle your menstrual cup according to our instructions, then it is safe to use. Flowcup is made from 100% medical-grade silicone. The silicone in Flowcup is 100% hypoallergenic, 100% latex-free, 100% fragrance-free and 100% free from artificial colours. The silicone we selected for Flowcup has also been tested, with favourable results, in accordance with USP Class VI protocols. Furthermore, our menstrual cups are manufactured under especially hygienic conditions where other medical components are manufactured, and the conditions we impose on the factory are extremely stringent. The United States’ equivalent to our National Food Agency is called the FDA, and they recommend replacing a menstrual cup every three years. We have chosen to follow the FDA’s recommendations.

Tampon sickness or toxic shock syndrome (TSS) is a very rare complication that may arise in certain bacterial infections. You can read more at 1177 . Most people get the illness in association with a skin infection, for example, an infection of a wound after an operation. It’s also good to be aware that most cases of TSS have nothing to do with menstruation or the use of tampons. To the best of our knowledge, there has only been a single case of TSS in the world associated with a menstrual cup, despite there being millions of menstrual cup users. Always think about hand hygiene and, to be on the safe side, do not use the menstrual cup if you have any sores in your vagina.

Companies that work with disposable sanitary protection such as pads and tampons prefer to have repeat customers rather than customers who rarely make a purchase, such as menstrual cup customers. So marketing menstrual cups is not as appealing for them. We who work at Flowcup have followed the menstrual cup market for seven years. Compared with the surveys we performed in 2010, we observe a rapidly rising trend for menstrual cups. We believe that menstrual cups are the sanitary protection of the future.

Yes, you can, but only water-based lubricants as the Flowcup menstrual cup is made from silicone. We advise rinsing the cup with a little water before inserting it to create a bit more moisture.

The Flowcup menstrual cup is made from an extra soft silicone and adapts perfectly to your body. You won’t feel the cup if you have chosen the right size and inserted it correctly.

No. You should not have penetrative vaginal sex while the menstrual cup is inserted. If you desire and feel that you want to be caressed on the outer part of your vagina (on the outside by the clitoris), it’s all right with a menstrual cup inserted. Don’t let your period or menstrual cup control your sexual desire. Vaginal sex works perfectly well during menstruation, but not with a menstrual cup inserted.

When the cup is inside your vagina, it cannot get lost inside your body. It will stay in your vagina and you will get it out. If the cup has moved higher up your vagina and you find it difficult to get a grip on it, follow these instructions. 1. Try to relax. 2. Sit on the toilet or squat down. Use your lower abdominal muscles – with the aid of your vaginal musculature, use your lower abdominal muscle to push the cup downwards. 3. Carefully pull the cup out by taking hold of the ball stem at the bottom.

When the cup is correctly inserted and has opened up properly, it will not leak. If the cup becomes over full with fluid, it may leak. If you notice that, on certain days, you fill the cup with menstrual fluid, you can empty it more often than every 12 hours.

You can use a menstrual cup if you have a contraceptive coil. Consult a nurse at a family planning clinic or your GP if you have any questions about using a menstrual cup with a coil fitted. It’s possible to have the coil’s threads cut off so they don’t get in the way of the menstrual cup. Always wait at least three months after a coil has been fitted before you use a menstrual cup. It is important to relieve the pressure of the seal before you start to pull out the menstrual cup to relieve the pressure. This stops the coil from shifting position or being pulled out with the menstrual cup. Consult a family planning clinic or your GP about using a menstrual cup with a coil.

The Flowcup is perfect for exercising. Make sure you are used to the menstrual cup and how it works with your body to avoid leakage during a workout.

The menstrual cup creates a seal so the menstrual fluid stays in the cup and the water stays outside. You don’t need to remove the cup after swimming unless it needs to be emptied.

Yes, you can. The depth of the vagina varies from woman to woman. Women with a shorter vagina may need to trim off the ball stem at the bottom in order not to feel it in the vaginal opening.

When the menstrual cup’s uppermost part is just inside the vaginal opening, we recommend that you wiggle the cup a little by holding the little ball at the bottom. As you wiggle the cup gently and push it upwards a little at a time, you will let in a small amount of air. This makes it easier for the menstrual cup to unfold properly.

If you put some toilet tissue in the toilet before emptying the cup, you can avoid leaving a red stain in the toilet bowl after flushing.

Flowcup is made from 100% medical-grade silicone. The silicone in Flowcup is 100% hypoallergenic, 100% latex-free, 100% fragrance-free and 100% free from artificial colours. When we selected the silicone for the Flowcup menstrual cup, we chose a premium quality medical-grade silicone which is extra soft. Quality, safety and comfort have been keywords throughout the development of Flowcup.
