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.

Hi Valeria!
Unfortunately, we can not help you with the fitting of a menstrual disc, as those are not a part of our product range and we are not experts in that! We recommend contacting the company which you purchased your disc from :)
Best,
Team Lunette
Hello! So I just got a period disc and it’s a size regular that says it’s meant for medium/high cervix height but I know mine is low. I have been having heavier flows the first few days so I’m assuming it can help with that, but because I have a low cervix does it mean this disc will leak or be “loose”?
Hi Deepu,
when the cup causes pain, this often hints to the cup touching the cervix. It may cause discomfort or even pain, similar to menstrual cramps. Normally the pain stops when the cup is removed. This could be either because the cup is inserted too high or in case the cervix is coming really low. You can avoid this by placing the cup as low as possible. If the cup rises by itself, try this little trick to avoid it: when you insert the cup let it open before it is entirely inside your vagina, and push it in when it has opened. This way, the seal won’t become so strong.
If you want to check where your cervix is located during periods, simply insert a clean finger during your period and feel for it. It is a soft bulge in the vagina with an opening in the middle. If you can barely reach your cervix it is high. If you can easily reach it it is rather low.

Hi,
i trying menstrual cup for first time and have ordered small size from lunette.when i got cycle nd started using i m really feeling something is inside kinda feeling or slight pain after inserting.i have no idea whether the cup is above or below the cervix.as i push it deeper the suction happens nd slightly stem is visible.Help me out with a solution for this discomfort as I don’t wanna use sanitary pads again.
Hello, I recently started using my cup for the first time this week, i’m unsure of where my cervix sits but I did attempt to find it.. it was about a finger deep so I’m assuming it’s average, I’m still unsure i do know that when i insert my cup it tends to go up.. don’t know if that’s often an indication of a high or average cervix.. my issue is I experience leakage no too, too often.. It might be the way I’m inserting it because sometime I won’t have any and sometimes I will even if the cup isn’t entirely full.. every time I do use the cup however, I do have this brown blood residue I was curious if there’s a way to prevent that and as for leakage how could I prevent that as well? it may an issue with the insertion.. or i may need a bigger cup because of my cervix.. currently I use a Lena cup small..
Hi Appy!
The most important thing is to relax! If you are nervous, you may tense your muscles to make it even hard to remove the Lunette Menstrual Cup. So try to be as relaxed as possible and find a comfortable position. When being scared you automatically tense up and this makes the vaginal muscles go tense. Imagine holding something in your fist and clenching your fist really tight. It will be more difficult to pull the thing in your fist out compared to holding it relaxed in your fist. It is quite similar with being relaxed or tensed up – the tensed muscles hold your cup really tight and removal is more difficult.
When removing the Menstrual Cup, always remember to use your own muscles. Push the cup down with your pelvic floor muscles like you’d be pooping until you can get a firm grip from the bottom. Pinch the bottom with your forefinger and thumb to release the seal. Then keep pushing while slowly pulling the cup out. You can also rock it from side to side. You can fold the cup a bit with one hand by grabbing the cup with the forefinger, middle finger and thumb. Place the fingers around the cup and push your thumb between the fore and middle finger. That way you kinda fold the cup as a c-fold and it is easier to get out. Be sure not to pull it out by the stem alone – this can cause the contents to spill, may cause discomfort and can break the stem.
You can also try this trick: slide your finger along the side of the cup (your finger between the cup and vaginal wall) and bend your finger when you reach the rim. Then slowly pull the folded cup out.
Going into a deep squat with your legs apart can also help. This way the vagina is more open and the cup is automatically being moved down a bit. And then, as already mentioned above, push with your muscles as if pooping so that the cup is pushed down and grab the bottom of the cup. Squeeze it, keep it squeezed and carefully pull the cup out.
Make sure to stay relax, release the seal before pulling out and glide the cup carefully and slowly out. You can also use a water-based lubricant to soften the vaginal entrance to add glide for easier removal.

Hi, Thanks for the article.
I have been using menstrual cup for 3 years. But lately I find my cervix sitting inside the cup because of which the seal doesn’t break no matter how much I try and with utmost difficulty I pull it out. But then I get scared and push the cervix with a finger and it seems to go back to its original position during my menses. I recently switched to M size from an S size cup, and I figured maybe the cup size is not right for me. But in next cycle I tried the older size cup and it happened again. And now I am scared. I don’t know what to do.
Hi Misa,
good to hear that wearing the cervix in the cup is not causing any pain or discomfort :) Do you still have the stem on your cup? If yes, shortening or cutting it away completely makes the cup shorter and it can be worn lower in the vagina.
One thing you can try right off the bat is turning your cup inside out before inserting it. Inside out, not upside down… What this will do is shorten the cup. Please know that if you do this it will mean the base of the cup will be smooth and you won’t have the grips at the bottom of the cup to aid in removal. If you find that this works, you’ll want to trim the stem so that it doesn’t cause you any discomfort.

I have a low cervix and it sits inside my cup i am not experiencing any pain or any discomfort but i am scared. I try wearing it low but it will go higher. What should i do?
Hi Aakanchha and thank you for your message!
Sorry to hear that you’ve been having problems with your cup!
The pain is most likely caused by the fact that the cup touches your cervix. It is not dangerous but it can feel very uncomfortable or even hurt. You can avoid this by placing the cup as low as possible. Using a shorter cup may also help, as a shorter cup needs less space and is not as close to the cervix as a long cup.
If the cup rises by itself try this little trick to avoid it: when you insert the cup let it open before it is completely inside your vagina, and push it in when it has opened. This way the seal won’t become so strong :)

I’m an asian woman with no idea how high or low my cervix are. But i’ve been using lunette model 1 for 6 months and it always leak eventhough it has opened and i put it so low the stem is out. How to troubleshoot this? And everytime i want to empty it i always find my cup so deep inside. It’s like it move deeper. I dont want to give up my mc but i find it frustating to always leak no matter what i do.
Re: fara’s comment
That is happen to me as well and i have been hesitant to try my diva cup again… it happen twice so i know it was the cup. Tried one month without and had the cramps i usually would. But when i had used the cup prior to this new pain it actually eleviated my cramps this pain however is completely different and doesn’t go away after i take the cup out. It’ll last hours until it subsides.
Hi Rylla! Thanks for your question! It can be that your cervix is lower this month and is pushing the Cup out. It’s normal for cervix position to change along your cycle and life, things like diet, exercise, birth control and more/less sex and effect the position. If you have further questions don’t hesitate to reach out to us at info@lunette.com, our Menstrual Mentors are happy to assist! :)

Hi
I’ve been using a menstrual cup for about 3 months.
Last month was great and it worked perfectly
This month I notice that even though the seal has been activated (when I tug the stem it doesn’t come out) the cup feels like it’s too low, when I squat I can feel the base of the cup.
Is this normal?
Hi Laura! Thanks for your message! Try wearing the Cup lower if possible. If the stem of the Cup protrudes you can trim it, or cut it off completely. If you have the larger size Model 2 Cup, then the smaller Model 1 Cup is recommended as it is typically more comfortable with a low cervix. Don’t hesitate to reach out to us at info@lunette.com if you have further questions, our Menstrual Mentors are happy to help! ☺️

My cervix is low and it sits inside the cup. There is no leakage but the suction of the cup or it touching the cervix hurts my cervix sometimes. Do i need a different size or style of cup?
Hi Fara!
Thanks for reaching out! If you feel like something is off and causing you concern it’s always best to contact your doctor.
Best,
Team Lunette
I’d used cup for 10 months but now I can’t sustain it inside my body and it causes pain, however without it I’m ok. I feel tight inside my vagina. Should I see a doctor? I visited doctor 4 months ago but just had vaginal check up without any sonography
