Flow Cups

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.


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 cleaning bag with 100ml of water and microwave it at 750 watts for three minutes.

While on your period it is enough to rinse your cup with water when you empty it.

Yes. If you follow the manual and handle your menstrual cup according to our instructions, then it is safe to use. Our Flow Cups are made from 100% medical-grade silicone. The silicone 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. 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 Flow Cups are made from silicone. We advise rinsing the cup with a little water before inserting it to create a bit more moisture.

The Flow Cups are 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 alright 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 Flow Cups are 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.

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

Flow Undies

Flow Undies looks like and are worn just like regular underwear. In addition to being stylish and comfortable, they are expertly designed to absorb menstrual blood and lock it inside. They can be used as your only protection or together with a menstrual cup for extra safety. After use, they are washed, dried and ready to be used again.

Read more about it here.

It all depends on how heavy your menstrual flow is. You should change them when they feel wet. They can be used for at least 6 hours.

It is practical to have at least four pairs, then you have enough to use both during the day and night while having a clean pant ready for use and one on the drying rack.

In the crotch there is a slim, four-layer absorbent technology. The Flow Undies Moderate Flow can absorb up to 15 ml of blood and Flow Undies Heavy Flow holds up to 4 tampons, corresponding to 40 ml of period. Read more about it here.

Our sizes are true to size so you can choose the same size as you normally use for underwear.

See our size chart for measurements here.

The body and inner lining of Flow Undies Moderate Flow are made of soft, stretchy, organic cotton-spandex and the absorbent area contains microfleece and PUL. The materials are GOTS and OEKO-TEX certified. 

The GOTS label (Global Organic Textile Standard) proves that the material is produced ethically, in safe working conditions with no child labour and the OEKO-TEX label shows that there are no harmful chemicals in the pants.

Flow Undies Heavy Flow are made of a super soft, breathable and comfortable material. It's GOTS and OEKO-TEX certified and quick drying. The waterproof soft stripes surrounding the absorbent area to keeps you extra safe from leaks.

  • Rinse in cool water after use, then handwash or throw in the machine, using a delicate cycle and cool temperature (maximum 40°C). Wash with similar colours. Remember, cool temperatures are best at rinsing out blood stains.  
  • Do not use fabric softener or bleach.  
  • Hang dry only! Do not tumble dry or iron.

They will last at least 50 washes if you follow the laundry instructions.

  • If you rinse the pants with water and do not wash them immediately after, make sure to leave them to dry in an airy place. Foul smelling bugs hates oxygen. 
  • White vinegar is great as a deodorizer. You can either soak the pants in diluted vinegar (1 part vinegar and 3 parts water) or throw some vinegar in the machine before the last rinse 
  • If you have stubborn bloodstains in your pants, it is great to wash them in enzyme containing detergent. The enzyme eats up the blood stain and removes bad odour.
