• How to choose the right menstrual cup size for you!

    January 13, 2022 • GUIDES, LIFE

    Fear not! Firstly, choosing the right menstrual cup is not as hard as it sounds. Secondly, we are here to help! We hope to help guide you through the decision-making process to help you find a fit you are comfortable with. Remember that menstrual cups work by creating a seal; when a menstrual cup is worn correctly, it will be leak-free and comfortable. 

    The truth is, whichever size you opt for will likely function; however, because a menstrual cup is an investment that you will have for a while, it’s best to ensure the size you choose will best serve you for your unique requirements over the years to come. Everybody is different, and multiple factors could affect the sizing selection of a menstrual cup.

    How do most companies size their menstrual cups?

    No two brands will have the same system for sizing their menstrual cups, and there isn’t a generalised “size guide” that you can apply across the board. Generally, the size of a menstrual cup refers to the diameter. We will break down the sizes offered by the brands you find here at Biome.

    The Hevea Loop cup

    The Hevea Loop cup comes in three different sizes. The range includes; Size 1, Size 2 and Size 3. There is an increase in the length, diameter, and capacity for each size.

    • Size 1 – Holds 18ml and has a 40mm diameter (Recommended for first-time users of a menstrual cup or a teenager or have a light flow.)
    • Size 2 – Holds 25ml and has a 43mm diameter (Recommended for those who have not given birth or have a medium flow)
    • Size 3 – Holds 30ml and has a 45mm diameter. (The size 3 is recommended for those who have given birth vaginally or a heavy flow) 

    If you are still unsure about sizing, here is an image explaining how to measure your cervix and the recommended size.

    The Lunette menstrual cup

    The Lunette menstrual cup comes in two sizes (each size comes in three different colours; clear, purple and blue!) size 1 and size 2.  All of the Lunette cups are soft and pliable, however, the size 1 is made of softer silicone than the size 2. The softer silicone could be a better match for younger and first-time users and those with a more sensitive bladder.  

    • The size 1 holds 25ml and has a diameter of 41mm. (Recommended for light to normal flow or teens and young adults)
    • The size 2 holds 30ml and has a diameter of 46mm. (Recommended for normal to heavy flow)

    Some other things to consider:

    Flow

    Flow can be impacted for a number of reasons and it can change through different stages of life, identifying your flow will help you find the size that works for you. A general guide for identifying a heavy flow is as follows; If you note 80ml or more for your entire cycle or 16 soaked tampons or pads for a whole process (1) or you needed to change a tampon or pad every few hours. As flow is self-identified, have patience with yourself as you find what works for you and your body. 

    Age

    Teens and younger adults are more likely to find the smaller sizes more comfortable. The smaller sizes will make for easier inserting and removing, making the transition to menstrual cups more comfortable. As some women age, they can experience a loss of pelvic floor muscle definition due to hormonal changes. Therefore the larger sizes might be a more suitable match. 

    Pregnancy

    Pregnancy is a highly individual journey, and everybody reacts and transforms differently to going through pregnancy. Usually, the larger sizes will suit somebody who has delivered a child through vaginal birth.

    It is recommended to avoid using a menstrual cup during pregnancy and for postpartum bleeding or discharge.

    Cervix

    As menstrual cups are worn in the vaginal canal, sitting below the cervix, the cervix length can be a factor in finding the right fit for you. For example, if you have a lower sitting cervix, a shorter model would be a better fit. For the best result, we recommend measuring the length of your cervix to know which range you fall into. Also, remember to measure your cervix while you are on your period; this is because your cervix moves throughout your cycle. 

    Lifestyle

    Lifestyle is another factor to consider when choosing your menstrual cup size. If you have an active lifestyle and strong pelvic floor muscles, you will likely benefit from a smaller size. A firmer cup is also more suitable for somebody with a more active lifestyle, as if the cup is too soft, it could get crushed during movement, which could cause leaking. 

    Bladder 

    For those who experience any form of bladder issue such as a sensitive bladder, it’s recommended to opt for a softer cup. The firmness can pressure your bladder and create a constant feeling of needing to go to the bathroom. It’s also not recommended to opt for a cup with a prominent rim, as this can also irritate and press on the bladder. Instead, it’s recommended to opt for a soft cup. 

    So what do we recommend for you?

    We recommend using all of the above information to decide based on your lifestyle and body. However, we know that a generalised recommendation is sometimes appreciated, so here’s ours. 

    We recommend teens and those with a lighter flow or those requiring a smaller size. 

    Diva’s size 0 and OrganiCup’s mini. 

    We recommend those who have not gone through pregnancy and experience normal flow.

    Juju’s model 1, OrganiCup’s size A, and Lunette’s size 1. 

    We recommend those who have gone through pregnancy, are over 30 or experience heavy flow. 

    Juju’s model 2, OrganiCup’s size B, and Lunette’s size 2. 

    For those with bladder sensitivities our OrganiCup range is the softest. 

    For those with very active lifestyles who want to minimise the risk of leaking we would recommend the Lunette 2 as our firmest cup. 

    If you have found that you have a very short cervix, we recommend the size 1 menstrual cup in the Lunette range or the model 4 in the Juju range. 

    We hope that you feel confident in finding the perfect fit! If you have any further questions or need any more information about choosing the right menstrual cup for you then please reach out to our customer service team at  shop@biome.com.au
