Hello everyone!
I am a 23 year old and I have never given birth. I use Mooncup B (small) for almost two years now and it made my periods less anoying but it always leaks. I did some research in the past months and I learned that it probably leaks for two reasons. One, I have a tilted cervix and the blood is mostlikely running past the cup (or on the edge of the cup). I’m still trying to learn to position my cup the best way to prevent leaks but so far I haven’t found the right position. Reason number two is I have heavy periods and on the second night I fill up the whole cup and the night pad, sometimes I set an alarm in the middle of the night to empty the cup and to change the pad.
I am thinking of buying a new cup, I want to buy Lalicup L. Do you think it will help or do you think it will still leak because of my tilted cervix? I’m thinking the wider rim should help get my cervix in the middle but I may be wrong. I would very apreciate any oppinion and suggestion.
Lena
Hi Lena!
I’m happy to hear that you have some knowledge about your body as well as that you did some research on what might be a good match for your next cup 🙂
The MoonCup is a fairly narrow cup compared to other cups on the market. Depending on which model you purchased – the older version had airholes quite low on the body, the capacity is pretty low, too.
I think the LaliCup might be a great match since it is wider (less target practice with your cervix!) and holds a really good capacity – medium 36ml & large 40ml. I feel that the medium will be a comfortable fit in length, but I’m unsure about the large.
How did the MoonCup fit you, lengthwise? Was it easy to reach or did you need to push in a bit to retrieve it? Do you know by any chance how low or high your tilted cervix is? If you did need to push in a bit more, then the large might be fine.
I have been using lena cup for about a year, i bought the small size and i leak it was a bad experience so i bought the bigger size and it made a great difference. I was very happy but now i am having some issues i feel like the cup moves or i can push it down very easy, and for the past four months on my first two days of my period i am having mayor leaks. I have also experience lately a bubbly sensation with the cup when im in the bathroom or when i move a alot and also sometimes is hard for me to pee or i feel like i have not finish. I feel like a may need to change it especially one for my heavy days but i am not sure which one will be the right for me.
Hi Sindy!
I’m sorry that you’re having some troubles with the Lena Cup. Leaking is never a good thing. I can understand your frustration 🙁
Personally, I only feel those bubbling/gurgling sensations when my cup is almost full (or doesn’t have very much capacity left due to my cervix occupying the space) and I need to empty it. Do you find it’s the same for you?
Are you using the original or the sensitive version? I had some firmness issues with the original large size Lena, but the sensitive version gave me no problems at all.
Before I suggest a couple of cups that might be more comfortable and have the capacity that you’re hoping for, can you tell me if the large Lena sat comfortably as in length? Were you able to reach it easily when it was in position correctly or did it feel too long?
Hello,
I have used the Sileu cup, tulip shape for two periods now. I have had 3 children and have a medium flow.
The problems are:
1). It is pressing on my bladder so I feel like to need to go more and also struggle to empty my bladder.
2). When I try to remove it after having it in over night it is really hard to get it out, a round loop at the base would be much easier to grab hold off.
The problem is I don’t know which is right for me. I have no idea if my cervix is low or high.
Can you make any suggestions? It took me 15 mins to get it out this morning!
Thank you.
Regards,
Miranda
Hi Miranda!
It sounds like the Sileu Tulip Cup might be too firm for you. The flared rim might also be the cause of some of that pressure as well as making it harder to reach.
I would suggest a cup that’s a bit softer and has a regular style of rim instead of a flared one. If you’re using the larger size and you’re having trouble reaching it, I suspect that your cervix is medium/high.
The EvaCup (USA version) might be a good match for you. It has a regular rim so that the cup doesn’t ride up as high (like with a flared rim), but also has a wide band for a secondary rim that gives it a bit of firmness to help it open. The cup is “V”-shaped for length and the body is on the softer side.
Another cup that migh work for you is the Venus Cup (large). It has a softer body that will be easy to pinch to release the suction. The rim is also a ‘regular’ style that will hopefully keep that extra pressure off of your bladder.
If you have some other cups in mind, I’d be happy to give you some of my thoughts about them 🙂
Hi there,
I have recently brought a menstrual cup – OI brand (NZ). I am 26, never been pregnant and have a medium flow. I find though that in the last 2 times I have used the cup, I feel some pressure on my bladder. I already have a sensitive bladder so this concerns me. Any recommendations?
Hi Sarah!
I’m sorry to hear that the OI cup isn’t working out perfectly for you 🙁 It does sound like you may have some bladder sensitivities.
Other symptoms may include: feeling the need to urinate more frequently, feeling like you don’t empty your bladder when you do urinate, a slow urine stream, or constipation.
The OI Cup is made of TPE. Do you prefer TPE over silicone or have silicone allergies that I should know about before sending some suggestions?
Besides the extra pressure, is the OI Cup comfortable in size, length, and shape?
Hi I’m trying to get some direction to narrow down which kind of menstrual cup to try first. I only use pads so far because when I tried tampons, they were uncomfortable, and I didn’t have the patience to keep trying. Problem is, the pads allow moisture to sit against my skin, so a few days into my period, my skin gets very irritated.
I am a virgin, apparently I have a smaller than usual vaginal opening, and when my GYN tried to do an abbreviated exam over a year ago, he had to vacate quickly since he ascertained he was causing pain. I am also quite overweight; I don’t know if that’s a factor or not. Also my flow isn’t especially heavy.
Based on this information, what would you suggest? I will determine the measurement re: my cervix later, but perhaps you have some suggestions anyway?
Hello Sarah!
I understand about wanting to find another alternative to tampons and pads. We all have our reasons, but irritation from pads or being uncomfortable with tampons (and pads too for that matter) are very common.
Menstrual Cups are going to be completely different from both. Since a menstrual cup is inserted, it is a little similar to a tampon in that sense. However, it won’t absorb your natural moisture so it might be a little, or even a lot easier and more comfortable than inserting a tampon. AND if you do feel dry, you’re always welcome to use some water-based personal lubricant to help ease the process.
Since you don’t have much experience with any type of insertion, I would suggest trying a cup that’s on the firmer side to help the cup open without a lot of coaxing. I would also suggest one that is on the narrower side for comfort in the inserting process.
If you aren’t sure if you have a low or high cervix, I would start with an “average” sized cup. In my opinion, it’s better to find out that a cup is too long and that you need to get something shorter, then finding out a cup is too short and having a difficult time trying to locate and remove it…which can be a scary thing for a new user.
I have three cups in mind (in no particular order):
1. Monthly Cup – Medium – This is the middle of the three sizes that they have to offer. This cup is the shortest in this list, but not by very much.
It has a soft body, but a secondary rim and upper rim that has a good firmness that will help this cup to open after the fold is released.
2. Diva Cup – Size 1 – This would be their middle size. They have 0,1,2 – This cup falls in the middle of the lengths in this list. The body on this cup is more narrow than the Monthly Cup.
3. Casco Cup – Small – This is the middle size. They offer a “mini”, small, and large. This cup is a bit longer than the Diva Cup and is also slightly softer.
If you have sensitivities at the vaginal area, I would suggest trying the Casco Cup. This cup has softer transitions (speed bumps) on the outside of the cup that may eliminate chafing for some.
Those are the three that I would suggest looking into without knowing an approximate measurement of your cervix.
Please know that these may be too long for comfort if you have a low to a very low cervix. If you find that these are too long, I would suggest trying the Casco Cup Mini.
Good Luck and let me know if you have any additional questions.
Happy New Year!
So I ordered the Dutchess cup from Amazon in size A (large) due to me age being 28 but no kids and I’m not sexually active. I have had my first period since I got the cup. The firmness seems ok, I didn’t find it technically difficult to insert however it seems big so a bit painful and uncomfortable. As soon as it went in I gave it a tug and it seemed to have formed a seal so it was a good relief that it was so much easier than what I read. I feel my cup maybe too big as I could feel it and it felt like constant pressure and a bit uncomfortable. And I have read you shouldn’t be able to feel it. I had no leaks over night. When it came to removal, the seal was so strong and it was over my cervix so pulling was only pulling in my cervix causing pain. I found it really hard as you have to place 2 fingers in to try get out when there was no space in there. Even with doing what it said to press on the sides to break the seal it didn’t work as my seal was not around the vaginal canal but rather over the cervix. I almost cried because I thought I may be one of the horror cases I read about who ended up in the ER or doctors to have it removed. But I went as high up as I could reach and as trying to push it off my cervix from one side and pull from the other. Eventually it came out. I had a moment of fear not to reuse but in determined to make the switch. My cervix isn’t low it seems medium but I think the cup is large as I put it back in it as very low and lose and just pacing it in slightly it went right back on to the cervix. After an hour I took it out and did try again to keep it lower by it went back into the cervix. I’m not sure what I’m doing wrong. From what I’ve been reading it shouldn’t go into your cervix but form a seal around the vaginal wall. Also it’s uncomfortable this was as I can feel the constant pressure on my cervix. Could someone please give me some insight. I’d greatly appticiate it.
First of all, congrats on deciding to take the leap to reusables! I know it’s a big step and there is a learning curve, but I hope that we can help sort any issues out.
I’m glad to hear that inserting the cup was fairly easy and that you experienced no leaking. However, you are right, you should not feel the cup after it is inserted.
The feeling of constant pressure or needing to urinate more frequently, feeling like the bladder isn’t completely emptied, a slow urine stream, or even constipation, can be signs that a cup is too firm and applying pressure to a sensitive area.
Changing the firmness or shape/size of the cup can help ease this pressure.

Does the cup always create a tight seal? It’s so strange that this issue is a hit or miss for many of us. Since we’re all different, each of us is going to have different experiences with a specific cup. In this case, I have never had the Dutchess Cup (or any others with the exact same design) create a tight seal for me. BUT, I know it happens often that cups that I don’t experience that with, others do and vice versa.
No one can guarantee that you won’t experience this with any given cup. However, it seems more common when cups have very small air holes or no air holes at all.
The only thing that I can suggest for this, it to try a cup that has more length to it for an easier reach, if possible.
______
When we insert a menstrual cup, even if we place it low, our muscles will tense up with regular movements and “squeeze” the cup. Depending on “fit” this can move the cup upwards into the vaginal fornix around the cervix, or push the cup out of the vagina.
Think about it this way…create an “O” around an egg by placing the pointer and thumb tips together. Then slow and gently close the diameter by squeezing the egg. You’ll find that the egg will start to move up or down. Probably upwards to sit on your fisted hand.
So you’re not doing anything wrong. Our PFM (pelvic floor muscles) play a big part in what’s happening. They tense up and relax with everyday movements.

With everything that you’ve shared with me, I had a few cups in mind that might make things a bit more comfortable and easier. You didn’t mention anything about how light or heavy your flow is, so I didn’t use that detail in my selection.
Dutchess Cup (large) Measurements for comparison:
Total Length: 65mm
w/o Stem: 54mm
Diameter: 46mm
Capacity to the Rim: 34ml
CASCO CUP small or large (not “mini”) – The size choice is yours depending on how light or heavy your flow is. These cups are both the same length, which even the small size is longer than the Dutchess Cup.
Although the small-sized Casco Cup has about the same firmness in the rim, this cup has a narrower diameter which may ease the pressure.
Total Length: 70mm
w/o Stem: 56mm
Diameter: 42mm
Capacity to the Rim: 30ml
The diameter of the large Casco Cup isn’t too far off of the Dutchess Cup but lacks the extra firmness that those rings near the rim add so it’s softer.
Total Length: 70mm
w/o Stem: 56mm
Diameter: 44mm
Capacity to the Rim: 40ml
Since both sizes are longer than the Dutchess, the base of the cup might be an easier reach to help break the seal.
PRISM CUP (large) – I only suggest the large size because the small size might be too short for an easy reach. This cup has a nice narrow body, a longer stem, and has a softer rim than the Dutchess. The air holes on this cup are larger and travel downward diagonally with the higher point starting inside of the cup. The large holes and placement might be key to a gentler seal or aid in breaking it without pain.
Total Length: 75mm
w/o Stem: 56mm
Diameter: 45mm
Capacity to the Rim: 35ml
VENUS CUP (large) – This cup has a softer body but has an invisable secondary rim and inner ring for added firmness to help the cup to open without being extremely firm.
Total Length: 71mm
w/o Stem: 56mm
Diameter: 47mm
Capacity to the Rim: 47ml
Check out these cups and see if any of them interest you. If you have additional questions about any of them, let me know 🙂
Until then, happy browsing!!
I had the ridiculous scary suction happen to be with the Blossom Cup, I lost it which I was sad about losing a cup but maybe it was for the best so I didn’t pull out my damn insides. I have a high cervix, I can barely even feel it.. I thought it was the material of the cup rather than the holes but whatever it is, it sucked right up and I had to put two fingers all the way in and try to grab and pinch the base while its continuously pulling up through its suction. Terrible experience.
I have Dot Cup, Bloody Buddy, and Lena and the Yuuki Striped Rainbow will be here tomorrow. I will be alternating them and figuring out where to go from there with this collection.
Hi Geraldine!
:O I’m so sorry that happened! I hope that one of the cups that will be arriving will be easier to work with. I don’t have the Dot Cup on hand (I find it very expensive), but I do have the Bloody Buddy, Lena, and the Yuuki. The one that I feel you might have the easiest time reaching, will be the Yuuki.
The Bloody Buddy (and other cups of the same design) are just a tad shorter than the Blossom (large) but have a longer stem. You’ll still need to reach the base of the cup to release the suction. Hopefully, the stem will help wiggle the cup down enough.
The Lena Cup is a bell-shaped cup WITH a flared rim. For many, this shape, especially those with a flared rim, tend to ride up and sit higher in the vaginal fornix. The rounded base also makes this design seem a little shorter. This can make things a bit difficult for those with a high cervix and the cup may be out of reach.
The Yuuki Cup (large) has a longer length body than the Blossom Cup and has a nice long stem compared to it, as well. Since this cup is a “V”-shape without a flared rim, it won’t ride up as much as a bell-shaped cup would.
The large Venus Cup might be something to look into. The body is on the longer side and might be easier to reach and pinch without reaching in as far.
Good Luck on your trials! Please keep me updated <3 I would love to hear about your experience with each.
I’ve been doing some research trying to find the right cup, I have the classic small MeLuna, I’m 24 and according to the obgyn I have a short vagina? I’m guessing low cervix? I have extremely painful periods and feel they are pretty heavy for about 2-3 and then lighter for the remainder, I have a difficult time inserting the cup and being able to tell if it has suctioned and it is also painful to take out, I used to use tampons but they were too painful so I bought the cup and reusable pads. I’m looking at the MeLuna short in small but I feel it may still be too firm. Please help!
Hi Brittany!
How is the length of the MeLuna? Does it still feel too long for you?
You could try turning the cup inside out…that is IF you’re comfortable removing a cup without a stem. This will shorten the cup by just a bit, as well as making it slightly more narrow.
If it’s comfortable this way, there’s no harm in continuing to use it. If it still feels too long, at least we know that you need something even shorter.
Here’s some info about inserting and removing a menstrual cup:
https://menstrualcupreviews.net/how-to-use-a-menstrual-cup/#Insert_and_remove
You might find some helpful info or tips in that video 🙂
Not all cups will create a tight seal for one person or another. After you insert the cup give it a gentle tug and see if there’s any resistance at all. If there is, chances are it created a seal. If it slides down easily, then it most likely didn’t create a seal. Try pinching the base a few times or inserting a finger and rotate the cup.
MeLuna may offer a “soft” version depending on your location. It’s not offered in the USA from their US website, but you may be able to purchase it from their Germany site or another site that carries their cups.
Hi, I was wondering what type of cup would be best for me. I am a skinny 17 year old virgin with heavy periods (I soak through super tampons in 4-6 hours on the first 2 days of my period.) However, the size above super is too big to fit comfortably. I’m not sure how high my cervix is (or how to tell). I am semi active, working a retail job, so lifting boxes and standing for long periods of time.
There are too many types and I don’t have a large budget to try all of them. Any advice would be appreciated :). Thanks!
Hi Em!
I would suggest checking out this link first:
https://menstrualcupreviews.net/how-to-choose-a-menstrual-cup/
It may help narrow down some cup options depending on what you want and need. You can also find info on how to locate and measure your cervix.
So far, I would suggest starting with a cup on the firmer side. It will be easier to open, as well as stay open during your (semi) activities unless you have a sensitive bladder or bowel in which I would suggest a medium/firm cup.
Until I know an approximate height of your cervix, I can’t really determine if I should suggest a short cup or a longer cup for you.
See if you can gather more info from visiting that link. I’d be happy to try to narrow some cups down for you after that.
😀
Ok so I am very new to the whole menstrual cup thing but I’m going to be living out of the country for over a year, and tampons will be pretty hard to come by. I am 19, a virgin, have a medium to high cervix, and I’m pretty active with a lot of walking and 30 mins of vigorous exercise just about every day. I do notice that when I have a tampon in it’s a little but harder to get everything out when I pee but that could also be my own fault of not putting it in carefully lol. I was thinking of getting the Lunette Bc it’s a V shape and still opens easily but I want to make sure that the one I get will for well and comfortably since I won’t be able to buy another one once I leave, and you’re the expert! Thank you for your help!!!
Hi Emma!
First I do have to say that I can’t guarantee that one or any of the cups that I suggest will work perfectly for you. Some people are lucky, have no problems with “fit” or comfortable with the first cup that they try. Others, might not be as fortunate. However, I can narrow a few down that might work better for you than some others.
The Lunette is a great cup, but it might be a little too firm if you have some issues urinating with a tampon in. I would probably choose something more middle of the road but has a decent firmness (at least in the rim) to stand up to you vigorous exercise routine.
Here are three cups that might interest you in order from the softest to the firmest rim:
Yuuki “Rainbow” – This is their softest firmness version which still has a good “pop” to it.
EvaCup – A soft body cup that has a wide secondary rim to help the mouth of the cup to open.
LaliCup – The medium is their “go to” cup in size. It’s the shortest of the bunch but still holds a nice 36ml to the rim for heavier periods. This cup has a unique channel pattern that helps it fold up smaller and easier as well as helps it open when the fold is released.
Yuuki “Soft” – The firmness of this cup compares more to an average “medium” firm cup instead of “soft”. A lot of people who do very physical activities say that this cup stays open for them during their workouts without being overly firm like the Yuuki “Classic” may be.
Lunette – This cup has the firmest rim of the bunch. Many love how well it pops open on its own, but others find it to be too firm for their sensitive bladder.
Check out each of the cups and see if any interest you 🙂
Good Luck!
Hi!
So I’ve been thinking for a few months about making the switch. I keep hearing too many great things!
I do have concerns and I’m a bit lost as to which one to get. The only one I’ve seen in store here (Australia) is the DivaCup. I’m perfectly happy to purchase online though as I want the best.
I have a-
-Heavy flow the first 2 days then trickles off to heavy “spotting” by day 5.
-Sensitive bladder.
-High cervix.
-I’ve given birth 6 years ago (I’m 26) but my partner says I’m just as tight as someone who hasn’t popped one and I have endometriosis (if either of those make a difference).
-Medium exercise level (my job is very active).
Part of the reason I want to walk away from tampons is the high level of animal testing that still happens. Do you know if these cups are cruelty free?
I’m concerned I’ll get “dry” with it in and become uncomfortable but I don’t like the feeling of lubes etc. Or that I’ll leak but who isn’t concerned about leaking.
Your help would be greatly appreciated!!
Thank you in advance!
I am not sure what cup to use and was hoping you could help. I tried the small diva cup and it wasn’t even close to fitting through my vaginal opening, it was very painful trying. I am 22 and have never had sex. I use tampons but super ones hurt going in and coming out and I can only fit one finger in it. I am not very active and have no idea where my cervix sits. My period is heavy the first two days then starts tapering off. Thanks in advance!
Hi There!
If you’re not opposed to shopping online, there’s a “hub” store located in New Zealand. That would be the closest (that I know of) to you. Search “Menstrual Cups NZ”.
I’m gonna work a little backward with your post 😛
First, “cruelty-free”.
There had been claims about “cruelty-free”, “not test on animals” and/or vegan/non-vegan cups.
It depends on how YOU define these terms. They’re not so black and white. It also may depend on how far back you want to trace the making of a menstrual cup.
If a cup is made of Medical Grade Silicone, it will also have a bio-compatibility certificate. Which means, there were a series of tests that were performed to determine if there is a potential toxicity when the silicone is in contact with living tissue. These tests were done on a “host” or “living tissue”.
Rabbits and/or rats were often used. Other tests may have been performed on living cells, but not actual living creatures. This testing was done long ago and is not performed regularly after the silicone supplier/manufacturer has established that their silicone is safe.
So…the cup company (the seller) didn’t do animal testing, the cup manufacturer (the company/facility that molds the cups) probably didn’t do animal testing, but the silicone manufacturer (the company that supplies the silicone) had to do some kind of testing to prove that the silicone was safe to be used on or within the body.
The silicone that is being used today by most of the reputable brands, were not tested on animals. After a silicone supplier has done all of the testings for biocompatibility and has established that their silicone is safe, they no longer need to continue to test the silicone on a regular basis.
BUT….there was testing done at some point.
Another issue, which is also not as black and white, has to do with how a person feels if the parent company offers other items that may have been tested on animals. An item/product may be manufactured to be cruelty-free for one company, but the manufacturer may also supply items which are not.
So again, it all depends on how far you want to backtrack.
“Tight” – It’s hard to pinpoint where people are referring to when they mention this. The vaginal opening or the pelvic floor muscles. It also doesn’t give me any accuracy as fingers, toys, penises, and other objects come in all sorts of shapes, sizes, and widths.
However, the vaginal opening is made of elastic tissues. It can stretch to accommodate something (a human) the size of a decent sized watermelon and then return to almost if not the same position after a short time.
The vaginal canal and vaginal fornix can stretch upward and outward 200 times its normal size. Again, returning to its previous shape/size/position after a short time.
The pelvic floor muscles can become weak, but they can also be toned once again with kegel exercises. A lot of time when we have penetrated intercourse, we tense this area which makes it feel smaller or “tighter”.
If you’ve used a tampon before, a menstrual cup will fold up with an insert point that is just about as small as a regular size/super tampon. Most large size menstrual cups are about the same width of an “average” sized penis.
With a heavy flow, I would suggest “average” or large capacity.
With a sensitive bladder, I would suggest a “medium” firm cup to start with. You don’t want to go too soft and have troubles opening a cup. Starting in the middle will allow you to go softer or more firm if it doesn’t suit you.
Having a high cervix, I would suggest “V”-shaped cups as opposed to “Bell”-shaped cups. Also stay away from flared rims if your cervix is very high. I would double check your cervix again during day 1-3 of your period to see if it drops down. This phase of your cycle is the lowest point at which your cervix will position itself. Around day 4 and on, it will start moving back up to it’s highest position at ovulation.
Your exercise level may be fine to start with (again) something in the “medium” firmness.
Here are some cups that come to mind based off of the info you’ve shared:
LaliCup medium or large – These cups have a unique channel pattern around the body to help this cup fold up smaller and easier, while also helping to open after the fold is released. These cups are higher capacity than the “average” cup without the added length. Although this is more of a bell-shaped cup, it has a regular style rim (and secondary rim) that will hopefully keep it from riding up and sitting too high for you to reach.
EvaCup large – This cup has a soft comfortable body but also has a higher and firmer secondary rim to help the mouth of the cup to open.
Yuuki large in “Rainbow” or “Soft” – These cups are on the longer side of “average”. If your cervix drops below “medium” this cup might feel too long.
The “Rainbow” version is the softest version that they have to offer. The “Soft” is actually more of a “medium” firmness compared to other cups on the market.
If you have heavy clotting with Endometriosis, I would probably narrow your choice to trying the LaliCup medium or large, first since they have the higher capacity.
I understand that you feel uncomfortable with lubricants, but if you feel dry, a WATER-based lube can be used with a silicone cup and then can be wiped away much easier than other types of lubes.
I hope this answered your questions, and I hope that you can find a cup that suits your wants and needs as well as be comfortable.
Good Luck!
