Every Lumma menstrual disc comes with a silicone string to help with removal however this can be removed if you prefer. The Lumma menstrual disc is the only menstrual disc that offers the silicone string.

Which size do I need?

First you need to measure the height of your cervix. You can find details on how to do this in our article "how to measure your cervix height". Once  you know this depending on the height of your cervix will dictate the disc you need. The round disc shape comforms to the shape of your body

Short - If you feel your cervix with your 1st knuckle inserted (up to 1½ in / 4 cm), you have a short cervix.
Medium - If you can only feel your cervix after inserting 2 knuckles (between 1½ in / 4 cm and 2½ in / 6 cm), you have a medium cervix.
High - If your cervix is more than 2½ inches away, you have a high cervix.

Menstrual Disc Material

The Lumma disc uk is made from medical grade silicone. Lumma Disc is completely phthalate free. As menstrual discs only hold menstrual fluid rather than absorb it as traditional tampons do, the menstrual disc will not dry yoru vaginal canal.

Mess Free Period Sex

So how do Lumma menstrual discs make “period sex” possible?

Unlike tampons, pads and menstrual cups, the lumma uk disc doesn't stay in the middle of the vagina canal instead they fit above the vaginal canal, right below the cervix. This higher position keeps the canal free for penetrative sex. As you can imagine, that makes all the difference. Your partner won’t even notice the disc is there. No more worrying about “that time of the month” getting in the way of romance. Wave goodbye to the old days, and say hello to a better sex life and a leak free period..

How To Insert

1.Squeeze the rim in the middle of the menstrual disc to form an “8” shape, maintaining the string in front of the disc.

2.Insert the disc into the vaginal canal.

3. Continue pushing the disc toward the end of the canal until you feel that it’s positioned under your cervix.

4. Push upwards on the front of the rim, securing it behind the pubic bone. Part of the silicone string will remain outside the entrance of the vagina.


How To Remove

Pull lightly and slowly with the front of the string until the rim of the disc slips off the pubic bone and lines up with the entrance to the vagina, then pull out gently with your fingers.

Menstrual Discs Overview

Menstrual Discs are made of medical grade silicone and the cup sits in the vaginal canal under the pubic bone.Unlike a menstrual cup a period disc does not use suction to say in place or your pelvic muscles. A menstrual disc is often used for mess free period sex. Cups and discs can both be used without increased risks of toxic shock syndrome. Menstrual discs come in different sizes and the Lumma Discs have a silicone string, menstrual discs offer a higher capacity than tampons. Once in the correct position even though a disc has a higher capacity than a bigger cup you will not be able to feel it. A disc holds more than a super tampon making a disc suitable whatever your menstrual flow. If you want even further reassurance against leaks you can always use period underwear but with a disc it is not usually needed. The Period Lady stocks most menstrual discs available in the UK.

Lumma Menstrual Cups

Lumma also make the Lumma cup range. Lumma cups UK offer a variety of menstrual cup sizes and capacities for high or low cervix. All made of medical grade polymer.

Discs FAQ's

What is a menstrual disc?

A menstrual disc works similarly to a menstrual cup in that it sits in the vaginal canal and collects menstrual blood.  A menstrual disc works differently because they don't suction into place in the vaginal canal. It sits length ways under the cervix and tucks under the public bone.
A menstrual disc can be a great alternative for those with higher cervix or those who are more sensitive and struggled with more traditional cups.

How does a menstrual discs work?

Menstrual disks are worn internally as a tampon but they do not absorb period flow. The disc body is very soft but the rim is firmer to ensure the disc holds it's shape. It is held in place behind the public bone and allows you to go about your day as normal.

You can go walking, swimming or even have penetrative sex.

Discs are usually safe for wear for 8-12 hours and will collect menstrual blood during that time. You must ensure you empty and clean your disc within this time frame to minimise the risk of toxic shock syndrome. When you practice good hygiene there is very low risk of infection and the disc or cup can be safely worn for every period.

Can my menstrual disc get lost in me?

ABSOLUTELY NOT!  Your cervix (opening to your uterus) blocks the way for anything to get past (apart from sperm). 

Is it uncomfortable to use a menstrual disc?

You shouldn't be able to feel the disc at all once it's in place.

Do I have to remove the menstrual disc when I go to the toilet?

No. You can go to the toilet as normal when wearing a menstrual disc. Some people prefer to remove their menstrual disc for a bowel movement but the choice is yours.

Does a period disc smell?

Absolutely NOT. Blood doesn't smell until it comes into contact with oxygen so unlike pads there won't be a smell as it's worn internally.  If you leave your disc in longer than 12 hours when it's removed there might be a slight smell but this will go with the blood being tipped away.

How often do you need to empty your menstrual disc?

This varies on your flow but on average 8-12 hours wear time is normal. Day 1 is more likely to be changed more frequently than the rest of your cycle.  If you have a very heavy cycle you may need to change more frequently. Remember menstural discs hold MORE than a tampon. 

Discs come in different sizes so change frequency is also influenced by the capacity of the disc.  Read our full article "How Often To Empty Your Menstrual Cup."

Can I put a menstrual discp in before my period starts?

YES!  This is one of the things I most love about my cup.  I've always had an irregular menstrual cycle varying from 5 weeks to 12 weeks (although much improved years ago having taken Agnus Castus).  I now use a period tracker so I get an estimated date from the app so when it's getting close I start using a menstrual cup and pop it in the morning just in case.  At the end of the day I check and I'm either still fine or surprise it's started!  No being unexpectedly caught out or stained underwear.  Using the cup was a real game changer for me with my irregular cycle. Full Details are found in our article "Can I Put My Menstrual Cup In Before My Period Starts."

Can you have sex with a menstrual disc in?

YES! The menstrual discs sit on the upper end of our vagina, under the cervix. Mess free sex is one of the main reasons people use a disc.

Many people who feel uncomfortable with period sex find they are happy to partake as the menstrual disc leaves them feeling cleaner and more confident.

Please be aware that even if menstrual discs lie below the cervix like diaphragms they can not be considered as birth control.

It is important to note that you can ONLY have sex with a menstrual disc and not a menstrual cup. The menstrual disc sits much higher than a cup so it is out of the way. A menstrual cut sits lower, is firmer and blocks the vaginal canal.  See our Separate article on "Sex and Menstrual Cups."

Can you use menstrual discs with an IUD?

Yes you can use most menstrual discs however be careful when removing so that you don't pull on the strings.

Brilliant product
07 October 2022  | 

Iíve only used the disc for one menstrual cycle but it works!
For years I struggled with a leaky cup, it just didnít work for me. A friend recommended the disc and I would like to recommend it to anyone who doesnít get on with the menstrual cup and wants to say goodbye to tampons. I watched a YouTube video before inserting it for the first time and it helped, gave me the confidence to trust it.
Plus Iíve learnt I have a low cervix and ordered a small.
Thank you

Good so far
20 December 2021  | 

I have used this for one cycle so far. I was really looking for a cup/dish which did not rely on suction as I have a coil and have struggled to remove suction based cups before. It certainly succeeds in this respect and has been very easy to insert and remove. The only criticism I would have is around sizing. Using the guide I purchased the size suitable for a high cervix however I found it exceptionally large. I have now purchased the smallest size which fits but doesn't hold as much. Basically, I'd recommend considering width as well as depth when selecting your size.
Overall this product has worked for me so far and I will continue to use it in the future.
