5 Menstrual Cup Positioning Tips to Prevent Leaks

There are a few different reasons why your menstrual cup might be leaking or feeling uncomfortable, and the position of your cup inside your body is one of them! The beauty of the human body is that we’re all made differently, inside and out. As great as this is, it also means there are no set ‘rules’ about which size menstrual cup will work for you or which position is best to wear your cup. It all depends on your body, and often comes down to trial and error. 

However, there are some general guidelines that work for most bodies when it comes to positioning your menstrual cup correctly to prevent leaks. 

Tip #1: Ensure your cup is inserted all the way

Our most important tip: ensure your cup is inserted fully into the vagina. This means the base of the cup should not be felt outside the body or right at the entrance to the vagina. If only the stem is protruding outside your body, you should trim it to size following these directions (the JuJu cup stem is easy to trim!). If the rounded base of your cup is protruding and it feels like you can’t possibly insert your cup any further, this might be an indication that you have a low cervix or short vaginal canal, so should choose a shorter cup like JuJu Model 4. Be sure to read these instructions on how to find your cervical position


Tip #2: Try wearing your cup higher in the vagina, but still below the cervix

This tip is particularly helpful for those who have a sensitive bladder, as wearing your cup a little higher will prevent pressure on the urethra. It may not be possible to wear your cup higher if you have a low cervix. If wearing your cup higher up, ensure it is still positioned below the cervix, not beside or behind it. Some people also like to wear their cup with the rim positioned around the cervix itself (also known as ‘putting your cervix inside your cup’).

Tip #3: Try wearing your cup lower down in the vagina

Some people find that wearing their cup lower down in the vagina is the key to eliminating leaks. If you have a high cervix or strong pelvic floor muscles, you might find that your cup naturally travels higher throughout the day even if you originally positioned it lower. This is okay, but if you have trouble reaching your cup to remove it follow these tips

Tip #4: Don’t position your cup beside, in front of or behind the cervix

Whether you wear your cup higher or lower, this tip is essential for preventing leaks. Many of us assume that the vagina is a ‘tube’ with the cervix and uterus located at the end, however, this is not the case. There can still be space behind, in front of or beside the cervix (known as the posterior, anterior or lateral fornix) where you may accidentally place your cup, which will result in your flow bypassing your cup altogether. And that means leaks! 

To get this one right, we advise running your index finger around the rim of your cup after it is inserted, and making sure you can feel that it is placed below your cervix rather than beside or behind it.

Tip #5: Always ensure your cup is fully opened

While checking the rim of your cup as described in Tip #4, ensure that your cup feels completely rounded without any dents. Your cup needs to be fully opened to create a seal with the vaginal walls and to ensure that your flow is not bypassing your cup.
