Menstrual cups may feel pretty new on the period product scene, but that's just because they're now beginning to edge into the mainstream market. Since the introduction of the first silicone menstrual cup in the early noughties - the renowned Mooncup - they have continued to grow in popularity, especially since we've been looking for more eco-friendly ways to live day-to-day.

Unlike tampons and pads, a menstrual cup can be used time and time again. Helping to cut back on single-use plastics, landfill build-up, and the cost of buying period products. It really adds up!

But what is a menstrual cup and how does it work? If you're cup-curious, we've shared everything you need to know and the best menstrual cups available to buy in the UK.

How does a menstrual cup work?

A menstrual cup is a conical shape cup made of soft and flexible, medical-grade silicone or latex rubber which you insert into the vagina to catch and hold your menstrual blood, rather than absorb it as a tampon or pad would.

How to use a menstrual cup

Before you use your menstrual cup, you should sterilise it first. Placing it in a pan of boiling water for 10 minutes and wash your hands before inserting.

Once it's cooled, tightly fold the cup in half to insert with the rim facing up. If this is a little tricky, you could try using a water-based lube on the outside of the cup to help reduce friction.

Position the cup a few inches below your cervix. Slightly lower than a tampon, and then release for a secure fit. Rotate it to create an airtight seal, and adjust or reposition if needed. Much like a tampon, you shouldn't be able to feel any discomfort.

To remove your menstrual cup - in a relaxed position, insert your index finger and thumb into your vagina and squeeze the cup base to release the seal. Then gently remove, keeping the cup upright.

Once it's out, empty your blood into the toilet, rinse, clean and wash, and you're ready to go again!

Don't worry if it takes you a little while to get to grips using a menstrual cup. With practice and usage, you'll become a pro in no time.

Should I use a menstrual cup?

The type of period product you use is completely down to personal preference. But here are some pros and cons to consider if you're thinking about a switch to the cup.

Pros

• Toxic Shock Syndrome is rare with tampon use, and it's even rare with menstrual cups

• As they're reusable, menstrual cups require a one-time purchase, making them much more cost-efficient

• They're great for the environment too. Reusing your menstrual cup is much more eco-friendly compared to using tampons or pads that'll likely end up in landfill

• Depending on your flow, you can wear a menstrual cup for longer between changes. Up to 12 hours - compared to tampons or pads

• As the menstrual cup forms an airtight seal, you're likely to experience less odour

Cons

• Not all sizes are suitable for older women or women that have given birth vaginally, so you'll need to be wary of this when trying to find the right one for you

• If you're allergic to silicone, rubber, or latex, this may not be suitable for you - make sure to check the label before buying to make sure

• Removal can be messy compared to tampons and pads that have absorbency. Likewise, you'll need to rinse out your cup after use, something that you'll need to consider if you're spending a long time away from home

• Menstrual cups are slightly harder to use but will become easier with repeated use

• If you have vaginismus, endometriosis, or uterine fibroids, you should check with your GP first

Which menstrual cup is right for you?

Finding the right option for you might take a bit of trial and error, but thankfully menstrual cups typically come in sizes small and large with guidance from each brand as to which should be the right fit.

You should select your cup size based on your age and history of childbirth - rather than your flow. You might with other period products, what's most important is that the cup is wide enough to stay in place to prevent it from shifting, becoming uncomfortable, or there being any leaks.

A small menstrual cup is recommended if:

• You typically use absorbency tampons

• You haven't had a vaginal birth

• You're under the age of 30

A large menstrual cup is recommended if:

• You have a weak pelvic floor

• You've had a vaginal birth

• You're over the age of 30

The best menstrual cups to buy in the UK

Mooncup The Original Silicone Menstrual Cup1 of 10

Mooncup® The Original Silicone Menstrual Cup

If you're looking for the menstrual cup favourite in the UK, we'd have to recommend the original Mooncup, available in sizes A and B. Made from soft, medical-grade silicone, this comfortable, convenient, and reliable cup will pay for itself after 6-8 months and is completely manufactured in the UK. Not to mention, it's multi-award winning too!

This size A cup is designed for those over 30 or women who have had a vaginal birth, whilst the size B is for under 30s or those who haven't given birth vaginally.

Promising review: "I am amazed at this product. I honestly wish I’d done it sooner. I’ve been eyeing them up and watching videos and reading reviews for what seems like forever. I do not get on with tampons at all so was really unsure if this would be right for me. Well it definitely is. I’ve got to grips with it very quickly, the instructions are so easy to follow. It feels very comfortable and works a charm. I am so shocked at how much of a difference it’s made already. This is definitely something to consider if you’re not of either pads or tampons. Cost wise this will be cheaper in the long run."

Lena Menstrual Cup2 of 10

Lena Menstrual Cup

Made from medical-grade silicone, the Lena Menstrual Cup can be worn for 12 consecutive hours and comes with a 100 per cent cotton bag for storage.

Available in pink, purple, grey, or turquoise, you'll receive one menstrual cup per pack in your choice of size: small or large.

Lena recommends the small cup for first time users or those with a light flow. And the large cup for experienced cup users or women with a heavy flow.

Promising review: "I love the Lena Cup! I had previously bought the Diva Cup as it was the most widely known brand and i thought it would be fine. But 2 cycles worth of trying and it kept ending up in a disaster. That's when I found the Lena Cup. My first thought was that it was a lot firmer so I had my doubts but within my first couple of tries it has been a dream! I got the smaller size which has worked perfectly for me. It comes with a little bag to keep it in (which is super cute) and an instructions manual and FAQs."

Saalt Soft Menstrual Cup3 of 10

Saalt Soft Menstrual Cup

Available in Desert Blush pink or grey, the Saalt Soft Menstrual Cup's made of ultra-soft silicone, ideal for those with sensitivities.

Available in sizes small and regular, Saalt recommend the smaller size for first time users, light flows, or those with a low cervix, and the larger size for a high cervix or heavy flows.

The large is designed to hold a higher capacity - three to four tampons worth, compared to the small cup that'll hold two to three tampons worth.

Promising review: "Already better than my moon cup. More comfortable, more secure. I thought my age was the issue, with my body changing. It might well be changing, but this cup is waaaay better suited to me now. I cannot feel it in place at all, and it is standing up to my heaviest day like a champ."

BeYou Menstrual Cup4 of 10

BeYou Menstrual Cup

Made from 100 per cent medical grade soft silicone, the BeYou Menstrual Cup can apparently last up to 10 years - imagine how much money you could save on pads and tampons in that time!

Available in medium and large, BeYou recommends the large for anyone over the age of 25, regardless of childbirth or not.

It also comes with a carry bag and tips to help you feel empowered on your menstrual cup journey.

Promising review: "As someone with endometriosis I have increasingly struggled with using tampons for deal with my period and always always had leaking, but my BeYou cup has majorly changed things for me! 1- I find it definitely easier than tampons and don’t experience any pain with it. 2- I haven’t had any leaking and can get through most of the day without needing to change the cup. 3- I am saving SO MUCH money with the cup vs pads and tampons. 4- This is so much more eco-friendly than normal tampons and pads!
"Honestly if you haven’t tried a menstrual cup before I highly highly recommend giving the BeYou cup a go. The material is really lightweight and I find it easier to use than most other cups that use a less bendable material."

Tampax Heavy Flow Menstrual Cup5 of 10

Tampax Heavy Flow Menstrual Cup

Bet you didn't know Tampax did a menstrual cup too? Made of 100 per cent medical grade silicone and clinically tested, the Tampax Menstrual Cup has been designed for women with a heavy-flow and would usually use super plus absorbencies.

With comfort-fit protection, a handy case for hygienic storage, and designed with a gynaecologist, it has the same, trusted Tampax protection.

Promising review: "This is the best one out there to date! Does exactly what it needs to an exactly what it says it will do! Doesn't leak or leave you worried about leakages. 1100% recommend this product."

&SISTERS The Nüdie Period Cup Large6 of 10

&SISTERS The Nüdie Period Cup Large

100 per cent hypoallergic with zero latex, the &SISTERS Nüdie Cup has a silky smooth finish with a easy-to-hold 'pebble' pull at the bottom for comfort.

Available in three sizes, this large cup can hold the equivalent of three tampons worth and is recommended to those who have given birth vaginally or are over the age of 30.

Promising review: "I bought this to try its the first cup I've tried, I was sick of spending a small fortune on sanitary products monthly. It did take me a few attempts to get it right, trying to relax but towards the end of my period I had gotten used to it, it's very comfortable and I can't feel it like with Tampax. It does not dry you out. I'm no longer buying Tampax, I'm sticking to cups. I would definitely recommend."

Intimina Lily Cup One7 of 10

Intimina Lily Cup One

This is a great menstrual cup for beginners for a number of reasons; it's soft and comfortable, has an easy removal loop, and is collapsible for easy storage and discreet carrying on-the-go.

Designed to be worn up to eight hours and made from 100 per cent medical grade silicone, its an affordable option for newbies to get used to using the cup.

However, this size is best suited to those with a low cervix, teens, of those to a light to medium flow.

Promising review: "I’ve been using this for about 6months now and it’s my first time using a cup. I think the whole idea takes a lot of getting used to and understand how to correctly fit it so that there are no leaks takes time. I am finally at the stage now where I know exactly how to use it without having to use a panty liner in case of leaks.
"I highly recommend getting a cup instead of tampons as it has so many more benefits - the most is I only have to change this once every 24h! Where as before I would have to change my tampon around once every 3h. Being able to fold this up into the little packaging is perfect for just popping it in your handbag or in your washbag in case of emergency. 100% recommend."

Hun. Menstrual Cup8 of 10

Hun. Menstrual Cup

Amazing value with two menstrual cups for the price of one, the Hun. Menstrual Cup is made from 100 per cent medical grade silicone and is naturally hypoallergenic.

Available in small, medium, or mixed sizing, the regular is recommended for those over 35-years-old, and anyone who has had a vaginal birth.

It also comes with a free, natural cotton canvas bag, making this one extra eco-friendly too.

Promising review: " This has transformed my periods! Saving pounds AND the environment (worked out I’ll save £100 a year on tampons) and no more pads of plastic filling up landfill!
Also way more comfy than tampons as the silicone isn’t drying, feels cleaner and not having to change as often is so convenient.
"I also love the fact the business is founded by a woman and champions female empowerment!"

Intimina Ziggy Cup9 of 10

Intimina Ziggy Cup

It's rumoured that you can have sex with a menstrual cup, and while this isn't the case with most, it is with the Intimina Ziggy Cup.

With an extra thin, flat fit design, this one will be a little different to fit as it's a disc, rather than a cup, but is still made from medical grade silicone with a leak proof double rim.

This one can cover heavy flow period and can be worn for up to eight hours with a handy silicone case for storage.

Promising review: "I was a bit sceptical that it would be too big for me and it would be uncomfortable as it seemed massive when I first opened it, but thankfully I was wrong. Seems there are other reviews that are quite bad which lead to me being quite sceptical but no, a bit of adjusting to make sure it was in properly each time, you can feel when it's not.
"Even on my heavy days, it's fine, it may need to be emptied which may be a bit tricky in public but seems to be fine with just a bit of tissue. It can be quite messy inserting, although it is easy to get out. It's perfect for mess-free sex, my partner can feel it in some positions but it doesn't bother him much."
