MoonCup Pros and Cons
The Mooncup Menstrual Cup has some very happy customers and many people try it as their first menstrual cup and end up sticking with if for the rest of their lives.
Here at Reusable Menstrual Cups, the MoonCup always finds its way onto our top 5 lists. It’s made in the Western world (we love menstrual cups from Europe, or North America) from top-quality medical grade silicone by a reputable company.
The design works well for most people and it’s often the first, and last cup that people end up using. It really is that good!
But, is the Moon Cup the right period cup for you? Keep on reading to find out! Or, head on over to Amazon to check out the user reviews and product description for yourself:
MoonCup: Based in the UK
The Moon Cup is a menstrual cup from an English company that is based in Brighton. The product is also fully manufactured in the UK.
It’s made from the highest quality medical grade, undied silicone and it’s approved for sale in the USA by the FDA. This is quite unusual and there are very few menstrual cups on this exclusive FDA list.
Related: FDA approved menstrual cups.
Similar to the Diva Cup
In terms of design and sizing, the MoonCup is very similar to the more popular Diva Cup. Honestly, the major difference between the two seems to be the fact that the MoonCup is based in the UK, while the Diva Cup is out of Canada.
The good news is that you really couldn’t go wrong with either of these choices, so shop freely!
Diva Cup: Slightly Stiffer Materials
In terms of design, there is a slight difference in that the Diva Cup is a bit stiffer than the Moon Cup. There are some advantages, and disadvantages to this. A stiff cup will pop open very easily when inserted.
However, a stiff cup can feel a bit uncomfortable because it presses very strongly against the vaginal canal walls. You may also experience cramping and discomfort if this is the case.
A softer cup may require a bit of work to insert it correctly, but it may feel more comfortable. The choice really is yours!
The difference is slight, and both of these cups are considered to be some of the firmer cups on the market today. If you find that the stiffer cups are uncomfortable, you many want to consider using one of the softer menstrual cups.
MoonCup User Reviews:
“I’ve been using the Moon Cup for 10 years now and have never looked back. Everyone should be using one of these things! I can’t believe I wasted so many not knowing about these things.”
“Good riddance to pads and tampons. I’ve never using those things again! The MoonCup in particular is very high quality compared to some of the other cups that I’ve tried. It’s easy to insert and remove and I’ve never had a problem with leaking, except for the first couple cycles. It took me a little bit to get the hang of it.”
“It was very comfortable and easy to use even on the first day. The instruction package that comes with it are very detailed and answer all the common questions you might have. The price is very reasonable, considering that you’re getting a product that replaces pads and tampons for years.”
You can easily get the MoonCup on Amazon today:
Two Sizes of Moon Cups
The Moon Cup comes in two sizes:
Size A (large): 28 ml capacity, 46 mm diameter, 71 mm in length.
Size B (small): 25 ml capacity, 43 mm diameter, 71 mm in length.
Both size A + B have a stem length of 21 mm, which can be trimmed to fit. In theory, this could be considered one of the shorter menstrual cups at around 50 mm in length, if you trim the stem completely.
However, if you have a low cervix, instead of trimming the stem on one of the longer ones like the MoonCup, you could consider a low cervix menstrual cup. While it’s not a big deal to trim the stem on a menstrual cup, we find that modifying a menstrual cup can cause it to not last as long as if you otherwise didn’t do this.
In particular, we recommend the FemmyCycle Low Cervix if you find that the stem on regular menstrual cups are consistently sticking out of your vaginal canal. It’s one of the shortest menstrual cups on the market today, at around 50 mm in length. It has kind of an unusual shape that just seems to work for many people with a low cervix.

Do you want to have a more eco-friendly, affordable, healthier period experience? Then buy the Mooncup directly from the company:

2. It’s sometimes difficult to find outside of the UK, but you can get it on Amazon US here.
3. Some people reported awkward sizing-the small leaks and the big one is uncomfortable. Something like the Meluna Cup with 8 different size/length combinations can work better for some women.
How to Insert and Remove a MoonCup
Here is some advice that the company offers for inserting and removing a Moon Cup.
How to Insert a MoonCup:
- Wash your hands
- Fold the MoonCup
- Insert it gently (it’s designed to sit low in the vaginal canal)
- There should be space between the top of the cup and the cervix
- If the stem is sticking out, you may need to trim it (start small)
- Make sure it’s sealed. You can do this by turning it a full circle in one direction, or running your finger all the way around the rim.
I can’t Get the Moon Cup to Open
The Mooncup is one of the stiffer menstrual cups. This means that for most people, it should just pop open pretty easily once inserted. However, if it doesn’t, there are a few things that you can try:
- Use a different menstrual cup fold. Some work better for some cups, and body types.
- Point the cup back, and down towards your tailbone, not up towards the sky. This will help to ensure that the Moon Cup is sitting right below your cervix, not in front of or behind it.
- Jiggle, or twist the Mooncup one direction, then the other if it doesn’t pop open.
- Run your finger around the rim to see if there are any obstructions.
Won’t Fully Open? Is your Mooncup too Big?
One reason that your Mooncup may not open fully is because it’s too big for you. No matter how many of these tips mentioned above, it’ll never fully open. It’s just too big, and there isn’t space inside your vaginal canal for it to open. Try a smaller cup size.
Can I Wear a MoonCup Overnight?
You may want to know if you can wear the Moon Cup overnight.
We have lots of good news for you! The MoonCup, along with most other menstrual cups are perfect for wearing overnight.
This is because jumbo tampons have a capacity of 10 ml, while the MoonCup holds 25 + 28ml. This means that if have to change your tampon every 3 hours on your heaviest flow day, you can now make it eight hours, or even a bit more with the Moon Cup.
The key thing to remember is to empty, clean and then reinsert your menstrual cup every 12 hours (maximum).
Did you ever think sleeping through the night without having to deal with your period would be possible? It is!
Can the Mooncup Overflow?
If you see menstrual fluid on your underwear, or pad when you’re wearing the Mooncup, you should suspect one of two things:
- It’s not inserted correctly. You would notice this after 1-2 hours of wearing your Mooncup, if not sooner than that during a heavy flow time.
- Your Mooncup is overflowing. You might suspect this after a few hours when your flow is heavy, or when you’re getting to 8+ hours without emptying your cup.
In terms of where the menstrual fluid goes when your cup is full, it doesn’t really get absorbed back up through your cervix into your uterus. The hole in your cervix is very small and gravity is definitely working against this.
The most logical place for it to go is over the edges of your Moon Cup and then onto your underwear.
How to Remove a MoonCup:
- Wash your hands
- Break the seal by grasping the base of the cup
- If it’s too high up, gently pull down on the stem until you can grasp the base
- Slide it out
Can a Mooncup Get Stuck?
If you’re never used a Moon Cup before, you may worry that it could get stuck. And, can it get lost “up there,” never to be found again? It’s a good question, but not actually something that you have to worry about.
You may find that your MoonCup is difficult to remove, particularly in the morning. This is because it can travel higher up in the vaginal canal while you sleep.
If this is the case, put on a pad to catch any leaks, and try to remove your Mooncup in an hour or two. Relax, take some deep breaths and try not to worry too much about it.
Still doesn’t work? Bear down with your pelvic floor muscles.
After that, get a trusted partner to help you, or consider going to the doctor. They should be able to remove it in seconds.
Tips for Removing your Moon Cup
Can a MoonCup Get Lost?
The opening to your cervix is so small that not a whole lot gets through there, except when giving birth. Certainly nothing as large as a menstrual cup will ever, ever get through the opening in the cervix!
It’s impossible for a menstrual cup to get lost, so don’t worry about it.
Cleaning and Storage of the MoonCup
The company says that the MoonCup is built well and designed to last for years, if you take care of it properly. Here are a few tips for how to keep your MoonCup is tip-top shape:
- Wash your hands before and after handling your MoonCup. This is a basic hygiene tip-you don’t wash to introduce all sorts of germs into your vaginal canal.
- During your period, wash the Moon Cup thoroughly with soap and water when you take it out. Be sure to wash off any soap residue well.
- You can also wash it with something like the DivaWash. Although it’s a bit expensive, you only have to use the tiniest amount because it lathers up so well. It does smell nice, but it’s not necessary and plain soap works well too.
- When your cycle is done, boil it in a pot of water for 5-7 minutes. Make sure to not let the pot boil dry! Or, use a sterilizing solution (what you would use for something like a baby bottle).
- The most important thing is to NOT store your MoonCup in an airtight container. Store it in the cloth bag that comes with it, or wrap it loosely in a piece of toilet paper and put it in a drawer.
- When traveling in underdeveloped countries, be sure to clean your Moon Cup with drinking water.
- Cleaning your cup in the microwave or dishwasher is not recommended.

What about Using the Moon Cup in Public Bathrooms
One tricky thing about using a menstrual cup is when you’re not at home. If this is the case, try to find a private bathroom stall (like at Starbucks, or a seldom used handicapped one).
However, if this is not possible, don’t despair and switch back to tampons! Here’s what you need to do:
- Wash your hands before going into the stall.
- Take our your Mooncup. You can rinse it with some bottled water, wipe it with clean paper towel, or use a menstrual cup wipe.
- Reinsert your Moon Menstrual Cup.
- Be sure to clean your Mooncup extra well when you get home with soap, or a menstrual cup wash.

How Often to Replace the MoonCup
The Moon Cup isn’t cheap! It only makes sense to consider how long it lasts before buying it. Here’s what the company says about how often to replace the MoonCup.
If you follow their instructions for care and cleaning, it should last for “years and years.”
You should replace your MoonCup is there are changes in the material, or shape. You’ll also want to replace it if splits, or becomes sticky.
Staining is not a reason to replace the cup however. This is normal and it happens to most clear or light coloured menstrual cups.
Based on our experience, most top-quality silicone menstrual cups can last for 5-10 years before they need to replaced.

Sex with a MoonCup?
A common question that people have is whether or not they can have sex with a MoonCup. Similar to all other menstrual cups, the answer is, it depends on what kind of sex!
For anything besides penetrative sex, it’s ideal because there are no strings hanging out as with a tampon. Your partner may not even know that you have your period.
However, for penetrative sex, it will be very uncomfortable for both parties involved. A menstrual cup is quite big and there simply isn’t enough room in there.
Trust us. People have tried having sex with the MoonCup, and other similar menstrual cups and results weren’t great. Like some serious discomfort, and leaking going on. It’s not pretty, so don’t even attempt it. Normal menstrual cups just weren’t designed for penetrative sex.
If you’re looking to have sex on your period, the non-messy way, we suggest disposable Soft Cups instead. They’re flat, and sit right up under the cervix, unlike the MoonCup which is designed to sit quite low in the vaginal canal.

Is the MoonCup Safe?
A great question that should be asked is whether or not menstrual cups, including the MoonCup are safe to use. They will be inside your body for up to a week each month, so it’s an important question.
Overall, the top-quality menstrual cups (including the Moon Cup) are perfectly safe to use. They are actually safer than tampons for a couple of reasons.
The reason you might want to make the switch from tampons to a MoonCup is that tampons contain chemicals and pesticides. Although there are only trace amounts, this exposure is cumulative and can add up over time to cause harm.
Clearly, menstrual cups are a much safer alternative than tampons.
Moon Cup and Toxic Shock Syndrome
An excellent question that people have is whether or not they can get Toxic Shock Syndrome (TSS) from using a MoonCup. And, is the risk of TSS higher with a menstrual cup, or tampon. Let’s take a look at the facts.
To date, there has only been one case of Toxic Shock Syndrome from menstrual cup usage. It happened with the Diva Cup, and resulted from the person cutting themselves when inserting the cup at the beginning of their period.
Compare this to tampons. There are thousands of reported cases each year from tampon usage.
However, it must be factored in that many, many more people use tampons than menstrual cups. Overall, your risk of TSS from tampon usage is very low, especially if you take precautions such as changing your tampon often enough, and using as low as absorbency as possible.
What is clear is that the risk of TSS from using a menstrual cup is extremely low, and it is a safer option than tampons.
Can I use the MoonCup with an IUD?
It is possible to use an IUD with a MoonCup (or other brand of menstrual cup). However, there are some additional precautions that must be taken, in order that your IUD won’t become dislodged. We also suggest consulting with your doctor about this matter before using a menstrual cup with an IUD.
Here are some tips for the MoonCup company about using their product along with an IUD:
- There should be space between the MoonCup and your cervix. If you have a low cervix, the MoonCup is probably not the cup for you.
- The MoonCup (and all other menstrual cups except the SoftCup) are designed to sit low in the vaginal canal. They should be as low as possible, as long as the stem doesn’t stick out because this will cause some serious discomfort.
- Always release the seal on the MoonCup before removing it. You can do this by squeezing in the sides of the cup. If you can’t reach the base of the cup, pull down gently on the stem until you can grasp the base. DO NOT pull the cup out entirely using the stem. This will create some serious suction which can dislodge your IUD.
- After each period, check your IUD strings. Make sure you can feel them, and that they haven’t moved. If they have, go to your doctor.

The MoonCup and Yeast Infections
In general, a menstrual cup can help to reduce the frequency of yeast infections, or the opposite problem, bacterial vaginosis for most people. There are two reasons for this.
The first way the MoonCup can help to reduce incidences of thrush is because it collects menstrual fluid, rather than absorbing it like with tampons. This helps to maintain the natural state of things in your vagina, which helps to reduce yeast infections.
The other reason is that the Moon Cup doesn’t contain trace amounts of toxic chemicals like non-organic tampons do. This helps maintain your pH balance and lead to fewer infections or problems.
However, some people experience an increase in yeast infections or thrush when using the MoonCup. It’s not common, but it does happen.
If this is the case, be sure you’re doing the following:
- Washing your hands before inserting, or removing the MoonCup. You don’t want to introduce any foreign bacteria into your vagina.
- Rinsing off any soap or menstrual cup wash very well. This stuff can throw off the pH balance and lead to yeast infections.
- Boiling your cup between periods for 5 minutes on the stove.
If you’re tried these things but still get yeast infections from your Mooncup, stop using it for a while and see if things clear up. Menstrual cups work for most people, but not everyone.
Can I Pee with a MoonCup In?
A question that many people have is whether or not they can pee with a MoonCup in. The short answer is: Yes, you can pee while wearing a menstrual cup.
Let’s talk anatomy for a minute. There are three holes down there: a urethra, anus, and vagina. You insert the MoonCup into your vagina, while pee comes out of the urethra, and poop out of the anus. In theory, wearing a menstrual cup shouldn’t interfere with either of these bodily functions.
However, the urethra and vagina are in a similar are. Because menstrual cups are quite big, they can push against your urethra a little bit. This can result in it taking a loooooong time to pee when wearing a cup. Or, it can even cause discomfort, or cramp like feelings.
If this is the case for you, switch to a softer menstrual cup. They don’t press so strongly against your vaginal canal walls, and you’ll likely find it more comfortable.
Can a MoonCup Cause Cramps?
Most people find that the MoonCup is very comfortable and in fact, they don’t even notice that they have it inside them.
However, some people experience cramps when using a menstrual cup. This can happen for a few different reasons.
The first reason is that they cup you’re using is too big, which can push very strongly against your vaginal canal walls and cause discomfort.
The next reasons why you may get cramps from the MoonCup is because it’s too stiff for you. This can also push strongly against your vaginal canal walls.
Finally, your urethra may be sensitive or it may be close in proximity to your vaginal canal. This can also cause cramping.
What’s the solution if you experience cramps from the Moon Cup? Try a softer menstrual cup, or a smaller sized one.

Is the Moon Menstrual Cup Messy?
If you’re never used a menstrual cup before, you might wonder whether or not using the Moon Cup is messy. You probably know how you can go through your entire period using tampons without touching any sort of menstrual fluid.
This is NOT the case with the Mooncup. You will get menstrual fluid on your hands, almost every single you remove the cup. And, quite often when you insert it. There’s just nothing you can really do about it.
However, it’s not as gross as you might think. It’s a natural body process and not actually a big deal. Most people find that they get used to it after a few cycles and don’t mind at all.
MoonCup vs Diva Cup
The Diva Cup and the Moon Cup are the two most popular menstrual cups in the world. In terms of design, materials, marketing and price, they are extremely similar. Which one is right for you?
MoonCups aren’t too wide and they have grips on them as well as a longer them so removal will be easier for beginners. Some people find that the stem on the Diva Cup is too slippery because of the lack of distinct rings on them. The MoonCup is definitely a bit better in this regard.
Both the MoonCup and the Diva Cup are manufactured from similar materials in Western countries (MoonCup: Uk, Diva Cup: Canada), so quality isn’t an issue here.
Either one is a great choice though so you’ll just have to see what works for your body.
For more information about the Diva Cup vs. the MoonCup, check out this detailed post:

MoonCup and Diva Cup: So Similar
A word of caution however. If you find either the MoonCup or the Diva Cup uncomfortable, or it leaks for whatever reason, don’t think that buying the other one will solve your problems. It likely won’t!
Consider another brand of menstrual cup instead.

Isn’t the MoonCup Kind of Expensive?
If you search for “menstrual cup” on Amazon, you’ll notice that there are pages and pages of results. There are almost 100 menstrual cups, and each cup has different colours, sizes, and styles.
You may notice that the MoonCup is one of the more expensive sanitary cups. There are some cheap menstrual cups from China that cost around $5-10. If you’re all about the frugal living, you may wonder if a cheap menstrual cups is a good buy.
The answer is no! We never recommend getting one of these very cheap menstrual cups. There are a whole lot of problems with them, but the biggest one is the materials used in them. In most cases, it’s low-quality silicone that isn’t medical grade.
Cheap menstrual cups are actually on our list of the Top 5 to Never Put into your Vagina.
The cheap cups are often very flimsy and can leak like crazy. This is because they never will really fully open, and seal inside of you. The other problem is that the material degrades very quickly, and you’ll probably end up buying a top-quality menstrual cup in a short matter of time.
Just skip over this step and get a good menstrual cup from the start. The MoonCup makes an excellent choice, and is indeed worth the higher price.
