What size menstrual cup is right for me?

Every body is individual, so the size of menstrual cup you need is completely dependent upon your unique body shape. The questions listed here, therefore, are tailored so that you can easily find out what size of cup you need. You can also take a look at a size guide to be sure. There are a few things we can discuss to make the decision easier, and get you a menstrual cup that will fit! 

How big is a menstrual cup? 

AllMatters cups come in three sizes: Mini (our smallest), Size A (our medium), and Size B (our largest). The bigger the menstrual cup, the more liquid it holds. So, the length and heaviness of your menstrual cycle, whether or not you have given birth, are important factors to take into consideration when deciding which cup to get. Of course, every body is made differently so you may buy a cup that is too big or too small, but AllMatters offer an exchange to make sure you get your size right!

This is our smallest-sized cup, and is recommended for those who are in their teens, or for those who need a smaller size. The cup holds 19 ml and is 58 mm in length. It’s also recommended for those who have a light menstrual flow.

Size A
This is our mid-sized cup, and is recommended for those who have not given birth vaginally. If your flow is moderate to heavy, this choice is probably the best for you, because it holds up to 27 ml of blood.

Size B
This is our largest-sized cup, which we recommend for those who have a very heavy flow, or have given birth vaginally. It is 73 mm in length, and holds up to 33 ml of menstrual blood.

Not a one size fits all

Although we offer guidance, it doesn’t mean that our recommendations will always work. Someone could have had a vaginal birth and need the size Mini, and another person who has a heavy flow might find the Size A rather than the Size B to be more comfortable, or vice versa. But, as AllMatters offers a size guarantee, there is no risk of losing your money if you choose the wrong cup!

What if it’s my first time using a cup? 

For first-time users, we find that trying a size Mini or Size A is the safest choice. You can start using the cup as soon as you get your period, but menstrual cups require you to be well-versed with your body. 

Other questions about menstrual cups

We know menstrual cups are relatively new to the market, so this can lead to a lot of questions. So, we went ahead and compiled a list of most-asked questions about menstrual cups. Just in case.

How to use a menstrual cup?

Using a menstrual cup for the first time can be daunting. We have a full list of instructions if you need something more detailed. 

How to insert your cup

  • Before inserting your cup, you should always wash your cup and your hands with a mild soap and warm water. 
  • Simply fold your cup in either a ‘c fold’, ‘punch down fold’, or any fold that is comfortable for you.
  • Find a comfortable position and insert your cup.
  • Once it makes a little pop noise and feels secure, you’re good to go! 

How to take out your cup

  • Always wash your hands with a mild soap before touching yourself or your cup. 
  • Find a comfortable position and relax.
  • Pinch the base of the menstrual cup and gently pull it out; if it feels stuck, break the seal with your finger on the side and then pinch and remove.
  • Empty the cup into the toilet or sink, then rinse the cup and reinsert!

Can virgins wear a menstrual cup?

Yes! Anyone who has periods can use menstrual cups. They do not damage the hymen, or cause internal damage. They are perfectly safe to use as long as you follow the instructions. 

Can I use a menstrual cup if I have a tilted uterus?

Yes, it should be perfectly safe, although you should ask your doctor if you have any concerns.

Should I wear extra period protection with a menstrual cup?

If it is your first time using a menstrual cup, yes. We recommend you use some back up protection until you are sure you’re inserting your cup correctly. Like any period product, a menstrual cup can take some time to get used to. You can use a pad, panty liner, or even period underwear whilst you get to know your cup. 

Do menstrual cups hurt?

When used correctly and when you have the right size, a menstrual cup should never hurt. Like a tampon, you should not be able to feel it once it is correctly inserted. If for any reason you’re experiencing pain from the cup, remove it immediately and try to reinsert it. If you’re continually having pain you might need to see a doctor.

Do menstrual cups damage the cervix? 

Nope, menstrual cups are perfectly safe and do no harm to the cervix.

What cup to buy if you're active?

If you’re very active – whether you are an athlete or spend your days at the gym – you should look for a cup that is made from a firm material. This is because your pelvic floor muscles can crush your cup and cause it to move, risking leaks. 

What if the menstrual cup feels too big?

If your menstrual cup is inserted correctly and feels too big you probably need a smaller size! Simply take the cup out and exchange it for a smaller one.
