Let's tackle period poverty together.

Sign me uppppp

Did you know, that each person that menstruates, is estimated to use 11,000-15,000 tampons and pads in their lifetime.

These products contain 90% plastic.

87% of period waste ends up on landfills, in our oceans and on our shores.

It then takes between 500-1,000 years to breakdown, releasing harmful chemicals and microplastics into our eco-system, polluting our planet and killing our wildlife.

A single menstrual cup on the other hand lasts for several years and is a healthier, leak free, comfortable and eco-friendly alternative.

Oh yeh! When you buy one, we donate one to tackle period poverty together.

Be a darl. Make the swap.

intheflow are a Social Enterprise from Brighton, UK. We are committed to offer premium quality products that are affordable and accessible for all. When you buy a menstrual cup from us, you are actively tackling period poverty and making a big impact on the environment as well as others. Thank you for your support!

  • Safe to wear to sleep

    Can you sleep with a menstrual cup in?

    The answer my friend, is yes.

    Not only are they far more comfortable when compared to pads and tampons, they are leak free with correct use, and safe to wear for up to 12 hours.

  • All shapes and sizes

    What size menstrual cup am I?

    We have a size for late teens (X), under 25's (A) and over 25's (B). Other considerations for menstrual cup sizing is how light or heavy your flow is and whether you have birthed vaginally.

    If you are unsure, you might like to buy our TwinPack.

  • The perfect companion

    Can you swim with a menstrual cup?


    Yep! intheflow menstrual cups are made from a premium medical-grade silicone. The stem is discreet and non-absorbent. If you are one to worry about the string of your tampon becoming wet and leaking, it's time you upgrade your period today.

Frequently asked questions

How do I know if an intheflow menstrual cup is right for me?

Many people are making the swap to a menstrual cup for many different reasons.

A big one is due to the environmental impact of traditional period products, but others are making the swap because it's a healthier, more affordable, and more comfortable alternative to tampons and sanitary towels.

You can wear your menstrual cup for up to 12 hours, day or night.

You can exercise and swim with your menstrual cup with less worry of leaking.

There are so many reasons why you should at least try our menstrual cup, but our favourite reason is that it helps us with our donations in an effort to tackle period poverty with our buy-one-give-one model.


We think you will love it!

How do I know what size to buy?

We have 2 sizes for you to choose from. Size A is our smaller menstrual cup and is suitable for under 25's or those that have light flows. Our Size B cup would suit someone that is over 25 or someone that has birthed vaginally. It is also suitable for someone that has a heavy flow, but with this, our Size A menstrual cup is still appropriate, it might just mean that you empty it more frequently.

We also have a money-saving Twin Pack for you to try our menstrual cups in both sizes, which has the added bonus of keeping one spare.

What comes in the box?

You will receive your intheflow menstrual cup in a cute little storage bag, alongside an instruction booklet and a free cleaning brush. Our QR code will direct you to our contact details for us to connect and support you with any questions you may have, with a link to our digital instructions.

What if I can't get it out?

That's a good question, and when you first start to use your intheflow menstrual cup, it will feel different from using a tampon.

That's due to our cups being designed to create a seal to stop you from leaking. We have air-holes that are broken on removal, which ensures you are able to break the seal and gently and slowly pull your cup out to empty it directly into the toilet, or some menstrual cup users like to empty it in the shower. You do you boo.

Top Tips

  • When removing your menstrual cup, squeeze the very top of the stem or the very bottom of the base of the cup and twist slightly to break the seal. Your menstrual cup should then wiggle and slide out with little to no fight

  • Try not to panic, it will come out. Relax, follow the instructions, and get in touch if you need to talk to us
  • Know that it is completely normal for it to take quite a few go's before feeling 100% comfortable with your technique. Hang on in there, darl.
  • If it doesn't feel comfortable, it's not in properly. Take it out and try again. You will know and feel when it's in properly and it takes a little practice.
  • You might like to have some tissue or a pad in your underwear as a backup until you are satisfied that you have got it right.

If you have any concerns, email hello@intheflow.online and we will call you right back.

Why intheflow?

For you, the planet, and others.

intheflow is a social enterprise from Brighton, UK. Our Founder is a Period Poverty and Environmental Activist that has deliberately built a brand and product for you, the planet, and others.

We are all about sustainability, protecting our planet, and helping others. Our main drive behind developing our catalogue is to tackle period poverty through donations, but this comes hand in hand with raising awareness and reducing the amount of plastic waste that ends up in our ocean, landfill and on our shores from period products and their packaging.

As an example, for every 10 people that make the swap to our intheflow menstrual cup, and with our donation of 10 under our buy-one-give-one model, we are saving the planet from an estimated 48,000 single-use tampons or pads.

The financial impact of that will save 20 people that menstruate approximately £31,800.

As well as our donations, our main goal is to fund our academy.

We are engaging with local schools and community centres to deliver workshops and mentoring services to young people.

Intheflow celebrates all genders, and as our catalogue grows, we aim to provide a number of sustainable alternatives that represent our diverse community, helping them feel more comfortable with their options.

We want you to find a product that feels right for you, and for you to feel as comfy in your body as possible. That looks very different for each person that menstruates. We've got you! watch this space and give us some time as we'd love to share this journey with you and celebrate the bigger impact of a tiny little cup.

How do I use an intheflow menstrual cup?

  • First, please ensure you sterilise your intheflow menstrual cup
  • Wash your hands before inserting and after removing your menstrual cup
  • Insert: Practice your folding technique (The C fold is most popular)
  • Place in a comfortable position, your menstrual cup will pop into place and create a seal if inserted correctly
  • Wear for up to 12 hours but always aim to empty it within 6 hours if you can. If you have a heavy flow, you might like to empty it more frequently

Removing your intheflow menstrual cup

  • Wash your hands
  • Find the stem and work your way up to the bottom of the cup, gently squeeze and twist to break the seal through the air-holes, and then in a slow and steady motion, pull the cup out gently and empty it into the toilet or whilst you are in the shower
  • Rinse with water and reinsert or clean and store in your free intheflow storage bag

I have an IUD (Coil). Is a menstrual cup safe for me to use?

There have been some instances of menstrual cup users of other brands reporting displacement of their IUD during use.

Although generally safe, as we are so new, (launched in 2023) we have no data of our own, so can only go on the research we have completed. Therefore, we strongly advise that you speak to your doctor, nurse, or gynaecologist for a thumbs up on whether they feel an intheflow menstrual cup is a safe option for you.

Here is some useful research

https://contraceptionmedicine.biomedcentral.com/articles/10.1186/s40834-022-00203-x

It's worth noting that 1 in 20 IUDs are naturally rejected by the body within the first 3 months of placement during menstruation.

The research and connection to the two may therefore be coincidental. It may not be due to the use correct use of a menstrual cup and more toward the incorrect technique when removing or emptying a menstrual cup. Eg, not breaking the air-seal properly.

At this time, there is not enough evidence, so please consult your own doctor or nurse for advice on this and if you experience any pain or discomfort, know that this is not normal and you should consult a doctor.

Intheflow Menstrual Cups are designed to sit lower than where an IUD is inserted and sits just below the cervix. If you have been told that you have a low-sitting cervix, a menstrual cup may not be for you.
