    This step-by-step guide to using a menstrual cup will take you smoothly through each stage. Here's how to get the very best out of your cup, and your period:

    1. Fold and hold
    Always start by washing your hands. Fold Ruby Cup using a fold that works best for you. Many start with the C-fold. If that does not work for you, try some of the other folds to make insertion easier. Every menstruator's anatomy is unique, so find the fold that works for you.

    2. Insert and ensure
    As with tampons, gently insert the folded cup into your vagina, tilting it back to the base of your spine. The cup should sit as low as it can comfortably sit inside your vagina, normally lower than a tampon but with the stem fully inside.

    When the cup is inside, it wants to pop open, creating a light suction. The suction is how the cup prevents leaks, so use your finger to check if it is fully unfolded. Twist or rotate the cup if you need to.

    Do not rush, take your time - it's like learning to use contact lenses.

    3. Use it up to twelve hours
    One of the great benefits of using a menstrual cup is that it can be used up to twelve hours. However, most menstrual cup users find they need to empty their cup in the morning and again in the evening.

    4. Remove and empty
    With clean hands, gently pull the stem of the cup downwards until you can reach and hold the base of the cup. Pinch the base to release the suction and take it out gently.
    You may need to use your pelvic muscles to push your lower cup in the vagina to help you reach the base with your fingers.

    When you've got your cup, empty it in the toilet, and rinse it with water.
    If you do not have access to water, you can wipe it with some tissue or simply reinsert it right after emptying it. But make sure to rinse it at your next available opportunity.

    5. Re-insert
    When your cup is rinsed, you can reinsert it, and you're ready to go again! 

    A Ruby Cup is always accompanied by an organic cotton bag for storage and a small booklet with instructions on how to use a menstrual cup.

  • Sizing

    Ruby Cup menstrual cup comes in two sizes: Small and Medium. 

    The two key factors to look out for when choosing the right size period cup are:

    • Position of your cervix.
    • Heaviness of your menstrual flow


    If you have a low cervix, we recommend the Small Ruby Cup. 
    If you have a high cervix, we recommend the Medium Ruby Cup.


    If you have a light to medium flow, we recommend the Small Ruby Cup.
    If you have a medium to heavy flow, we recommend the Medium Ruby Cup.


    Light flow and high cervix? We recommend the Medium Ruby Cup for ultimate comfort.

    Heavy flow and low cervix? Both cups work for you:

    • The Small Ruby Cup would need to be emptied more frequently
    • The Medium Ruby Cup holds more blood, but you probably have to cut the stem for comfort
