Menstrual cups and cervix height: What you need to know?
Do you know what your cervix looks like? If not, we highly recommend a quick Google image search. During menstruation, your cervix plays a key role in how your period flows and how your menstrual cup fits. Understanding where your period comes from doesn’t just help you feel more connected to your body, it empowers you.
Wait, what even is a cervix?
Think of it as the “neck” of your uterus. It’s a narrow, firm passage that sits between your uterus and vagina. During your period, blood flows through a tiny opening in the cervix into the vaginal canal. That’s right, your body channels menstrual blood through a pin-sized hole. How incredible is that?
Cervix position: why it matters?
Your cervix isn’t static, it moves throughout your cycle. For some people, it descends lower during menstruation. Normally, the cervix sits high in the vagina, and your menstrual cup rests below it. But if your cervix drops lower, it may sit inside the cup, which can affect comfort and cause leaks.
Tampons, by contrast, sit higher in the vaginal canal, closer to the cervix, so they interact with it differently.
Menstrual cup leaks and cervix height
Leaks are more common when:
- Your cervix moves lower during menstruation;
- Your cup is inserted too high, sitting next to or above the cervix;
- The cup doesn’t fully open or seal properly.
If your cup is leaking even though it’s fully open, try placing it lower in the vaginal canal, below the cervix. Some people find that their cervix fits best inside the cup - there’s no one-size-fits-all. You’ll know what feels right.
Postpartum cervix and pelvic floor
After childbirth, the cervix may naturally sit lower. If that’s you, pelvic floor exercises (like kegels) can help strengthen the muscles that support your uterus and vaginal canal. Bonus: they also reduce incontinence and improve sexual function. Win-win.
Can’t find your cervix?
If you’ve never had leaks and still can’t locate your cervix, don’t stress. You’re likely one of many people with a high cervix, meaning it’s deeper in the vagina and harder to reach. This doesn’t affect your ability to use a menstrual cup - just opt for a longer cup that’s easier to remove.
How to measure your cervix height?
Curious about your cervix position? Here’s a quick guide:
- Wash your hands.
- Insert a clean finger into your vagina.
- Feel for a firm, round bump (like the tip of your nose).
- Mark how far your finger goes in, then measure it.
- If you can’t reach it, you likely have a high cervix.
- If it’s close to the opening, it’s low.
Your cervix is a powerful part of your body’s internal landscape. Learning its position can help you choose the best menstrual cup and avoid leaks or discomfort. Whether it’s high, low, or somewhere in between your body knows what it’s doing.
