6 Reasons Your Menstrual Cup Keeps Leaking

If your menstrual cup keeps leaking, there’s a reason for it. Let’s dive into the 6 reasons why your period cup is leaking.

In this article /

    The DivaCup offers up to 12-hours of leak-free protection, right? So, why does your menstrual cup keep leaking? If you’re experiencing leaking problems when using the DivaCup, there’s a reason for it. Let’s dive in and get to the bottom of things.

    1. You’re New to Menstrual Cups

    If you’re new to menstrual cups and notice leaking, it very well could just be part of the learning curve. Using a menstrual cup isn’t the same as using a tampon. Even though both are internal period products, they’re very different. For starters, menstrual cups collect flow; tampons absorb.

    The truth is many people experience a learning curve when using a menstrual cup for the first time. Which is why we have a plethora of helpful resources on our website.

    Not sure how to insert a menstrual cup? We’ve got you covered. Confused about how to remove your period cup? No problem. Not sure how to care and clean for your new DivaCup? We can help with that one too. And our Consumer Support Team is always here if you still have any questions or concerns.

    Whether you’re using menstrual cup for the first time or have been for a while, there is most definitely a valid reason for why your menstrual cup keeps leaking. Continue reading for more solutions.

    2. Your Menstrual Cup Isn’t Inserted Correctly

    The most probable cause of leaking is that your menstrual cup isn’t inserted correctly. Remember the DivaCup is designed to be worn horizontally, toward the tailbone, at the base of the vaginal canal.

    The best way to try insertion is to relax your muscles and then aim the cup toward your tailbone. Pay close attention to your wrist on the hand that is holding the cup. Be sure that as you insert, you are not twisting your wrist upwards, but rather that it is staying straight. If you are turning your wrist as you insert, the cup is most likely also being inserting upwards, rather than horizontally.

    We would also recommend trying our “Push Down” fold option as this can help the cup glide in easier, open and allow you to better position the cup at the opening. When you insert the cup horizontally, you should feel it slide into place at the base of the vaginal canal and open. If you find the cup is moving up the canal, it is most likely not fully open.

    Your Menstrual Cup Isn’t Opening Fully

    The reason your menstrual cup keeps leaking could be because the cup is not opening fully. Oftentimes it may feel as if the cup is open, but after feeling around the cup, you may realize there is still a part of it that is folded in. To fix this, once inserted, try sliding your finger along the outside of the cup and your vaginal wall, pressing gently on the sides of the cup. This should open the cup fully, creating the seal and will make rotation easier.

    Your Menstrual Cup is Inserted Too High

    When inserting, you also want to be sure to not push the tip of the stem further than ½ inch (1.27 cm) into the vagina. Inserting the DivaCup too high may cause leaks and may also make removal more difficult.

    The DivaCup is designed to sit low at the base of the vaginal canal, pointed towards the tailbone, away from the cervix. If you find that your cervix sits lower and you want to make sure it can still be distant friends with the DivaCup, it’s important to know that many people with a low cervix find great success with the DivaCup, since it’s designed to sit low. If you have any questions about the DivaCup and your cervix, our Consumer Support Team can walk you through it and answer any questions you have. They can be reached at

    3. You Haven’t Created a Seal

    The DivaCup shouldn’t leak if inserted correctly, and you’ve created a seal. To create a seal, insert the DivaCup, grip the base of the cup (not the stem), and turn the cup one complete rotation – 360 degrees.

    Another issue may be that one of the four holes around the brim may be blocked. You can test this by filling the cup with water, placing your palm over the opening, flipping the cup over and squeezing the water out. You want to ensure water is flowing through all four holes. These are important to ensure the seal is properly in place? Here’s a how to video on cleaning the four holes.

    4. You’re Using the Wrong Menstrual Cup Size

    Size matters. When choosing a menstrual cup, it’s important to do your research into what size is most appropriate for you. If you believe you’ve inserted the DivaCup correctly but are still experiencing leaking, you might have the wrong size.

    The DivaCup comes in three different sizes for different life stages:

    • Model 0: You’re new to the world of periods or 18 years of age or younger.
    • Model 1: You’re between the ages of 19 and 30 and have a medium menstrual flow.
    • Model 2: You’re over the age of 30 and/or have a heavier menstrual flow.

    However, just because you fit into one age group doesn’t mean that will necessarily be the right fit for you. If your DivaCup doesn’t feel right, connect with our Consumer Support Team and they can help you.

    5. You Have Strong Pelvic Floor Muscles OR They Need to be Strengthened

    Some women have also found that if their menstrual cup leaks, rides up near the cervix, or slides down, the vaginal muscles (pelvic floor muscles) may need to be strengthened utilizing exercises such as kegels.

    Alternatively, it may also be due to having strong vaginal muscles.

    Either way, if you think this could be the problem, we recommend you talk with a healthcare provider or a pelvic health physiotherapist as they can offer you some additional insight.

    6. Your Menstrual Cup is Full

    Finally, the answer could simply be your DivaCup leaking problems are because it’s full and overflowing. Some people experience heavier periods and find they need to empty and clean their menstrual cup every few hours, even though the DivaCup can be worn for up to 12-hours.

    If you notice your DivaCup is full when you empty it, and have leaks, we recommend emptying and cleaning it more often.
