Mooncup ® Review – How Does it Compare?

We are embraced by a modern world flourishing with the consciousness of saving this planet, sparing excess expense, and indulging in the better things in life that make our lives easier. The menstrual cup is one of those things that addresses all of these matters by providing a certain peace, convenience, and comfort to a woman that makes the burden of menses more bearable.

Sits very deep in the vaginal canal – a few customer testimonials on the Mooncup have stated that the Mooncup sites very high in the vaginal canal and can be difficult to remove. However, this could be because certain customers have a very high cervix or are not using the proper size for them.

Mooncup Menstrual Cup FAQS

Can the Mooncup be used if I have a retroverted (tipped or tilted) uterus?

You can safely use the Mooncup if you have a tipped uterus, however it may be tricky for you to get the right knack of positioning it. In some cases, women who have a tipped uterus are unable to get the protection needed for the Mooncup to be effective for them- so it may not work for all.

Can I trim the stem of my Mooncup so it is easier to handle and shorter?

Yes, the Mooncup’s stem can be trimmed down to accommodate your custom needs. However, you need to be careful not to damage the stem. A damaged stem will cause the cup to leak permanently.

Can I use the Mooncup if I just recently started my period?

Yes. The size B is smaller for girls who have just began their periods. However, if you are a virgin and want your hymen intact- you need to avoid use of the Mooncup.

Is the Mooncup compatible with the Nuvaring?

Yes, the Mooncup is perfectly safe to be used in combination with the Nuvaring, and other IUD devices. However if you experience a prolonged period of bleeding after using Nuvaring or an IUD with the Mooncup- you should discontinue use immediately.

Will the Mooncup intensify my menstrual cramps?

No, the Mooncup does not cause or intensify menstrual pain. In fact, many female users of the Mooncup claim that using this menstrual cup actually helps alleviate some of the pain and cramps associated with menstruation.

“I hear many menstrual cups cause candida/thrush (yeast infections)- will the Mooncup cause infections?”

The Mooncup is dye-free and allergy-safe so that it does not cause any adverse reactions such as vaginal infections, bladder infections, and candida/thrush (yeast) infections.

“Why is the Mooncup sold under the name MCUK cup in the United States?”

The Mooncup is FDA approved to sell safely in the US but the Mooncup cannot advertise this product based on that so they named the Mooncup USA version- MCUK.

“What is the Mooncups capacity in comparison to a tampon?”

A tampon can hold an average of 6-18ml of fluid in comparison to both sizes of the Mooncup which hold an average of 28-29.3 of fluid.

“Can I wear a Mooncup safely swimming, while participating in sports, and overnight?”

The Mooncup can be worn during activities such as swimming and while actively participating in exercise and sports. It also can be worn confidently overnight for good protection, but it is advised that you empty your Mooncup every 6-8 hours to avoid leakage.

“Is the Mooncup safe for me if I suffer from a prolapse in my uterus, bladder, or bowels?”

A prolapse (or caving in) of any organ near the vaginal wall can alter the shape and position of the vaginal canal. It is best that you consult with a physician before using the Mooncup or avoid the use of menstrual cups entirely.

    Small size was brilliant. No leaks, no problems. Best thing I bought.

    Large size (post vaginal birth), frequently leaked with only a small amount of liquid in – tho I have a low cervix. Especially poor with heavy flow!

    + PROS: 1 purchase lasts u years of sanitary protection. Why wouldn't you?!
    - CONS: Silicone will stain over time, especially if it's not cleaned well before sterilisation. Choose another brand if u have a low cervix.

    It took about three periods to get used to (as my first cup) but now there’s no going back. I thought I had ‘lost’ it a couple of times in the early days, but you can just use your pelvic floor muscles to push it down so you can reach it. I have never leaked, or had any discomfort with it (it’s now been 4 years!).
    I like how it helps you feel more positive about your body, shows you how much blood you are losing, and in my case, it reduced my cramps and the length of period, significantly.
    It’s easy to clean and I’m happy not to be sending 11,000 tampons to landfill like the average UK woman does…

    I so wanted to be able to rave about my mooncup and re-iterate all the wonderful things I had read about them on their own site (I’ve since realised they don’t allow any kind of negative review on their site – I left one as did someone else I know and neither were added to the reviews of which you will only find 5 stars) This should have been a warning to me) although after my first 24 hours I was ready to rave about it. Aside from being a bit uncomfortable to insert and extract, all was good. Then came my 2nd night. As someone who suffers with heavy periods I always set an alarm for every 2 hours to change tampons, and not being 100% convinced about the mooncup as it was my first period using it, I did the same. Went to be at midnight, removed at 2 – all was fine. Same at 4, which then prompted me to think it was worth risking doubling up on the time (I didn’t have work so thought I’d try an 8am lay in too). At 7 I was woken by the most excruciating pain I’ve ever known. I’ve experienced labour pains, I’ve had a major kidney infection and a grumbling appendix and the pain of all 3 combined didn’t even come close. I also felt wet. Practically falling out of bed, I noticed the wet feeling came from the fact I was covered in blood – my sheets, my mattress (a memory foam one that I have had to replace) my pj’s and myself, covered. I made it to the bathroom believing the mooncup to have unsealed and upon trying to remove it couldn’t find it (I never cut the stem as I wanted to make sure I was fully comfortable with it before doing so yet still had nothing to grab on to for removing). I never found it and ended up phoning a friend (a nurse) who thankfully was able to remove it for me – a most embarrassing experience. Apparently what the reviews on this site don’t tell you (but ones I have found elsewhere do) is that the mooncup can in fact be vacuum sucked inside you; as a result there is then nothing stopping you from bleeding (as I did) and if it’s gone too far there’s nothing to grab to extract yourself. I tried squatting as it suggested, I tried relaxing (which isn’t easy when you’re in so much pain) but still nothing. Chatting with my friend who removed it for me afterwards I discovered that this happens more often than people would think and it didn’t happen because I was loose in that area (the reason I believed it may have happened although not something I thought I was, and thankfully my friend who removed it assured me I was anything but). In fact it was due to my un-looseness and good pelvic control that I was unable to extract it myself. Once it had been sucked in it was stuck. I guess I should have realised when I read through the reviews and didn’t come across a single negative one that all as not as it seems, as nothing is 100% perfect, but I bit the bullet and took the risk. I won’t make that mistake again with anything.

    I purchased a Mooncup type B. I am a 22 yo with a normal figure I guess (164 cm/63 kg), no baby and very little excercise (usually just walking, hiking, some light gym excercise etc..). Before the switch I was wearing both pads and tampons, tampons either “normal” or small/mini sized. I always thought I had a normal-heavy flow but since the switch I could actually check how much I bleed so I found out I dont bleed very much at all, even on the heaviest day my mooncup was only halfway full (and it is 15 ml cup I think :)) Mooncup itself is pretty standard cup in regard to sizing – just two options, a stem and six holes around the rim for better opening. I find that whereas the size of the rim of the cup is medium I guess, the thickness of the sides of the cup might be a little above average – which makes it a lot springy, firm etc. Therefore it unravels very easily and is a little bit tricky to get in – I have to really focus on pinching it properly as I insert it because as soon as my finger stop pinching it properly it starts opening – which might be difficult if the cup isnt fully in yet. Otherwise, I cant feel the cup when inserted properly far enough and I didnt remove the stem yet (although it is slightly at the opening of my vagina) because I only had it for two periods and I want to practice taking it out more before I shorten it or cut it off completely. With my – now discovered – mild flow I take out the cup only once 12 hours. It could probably go longer on most days but I dont want to go against instructions that much 😀 I boil it before and after a period for 7 min and store it in the fabric baggie I got it in. It is honestly the best thing ever.

    After buying a cheap generic brand and testing it out for a few months I decided to splash out and buy a mooncup.

    I wouldn’t say I’m an experienced menstrual cup user by any means but I have not yet experienced any leaks with the cup. If you do have any problems with leaks I’d recommend checking out preciousstarpads youtube channel she explains clearly why some women experience leaks.

    The mooncup is definitely a firm cup, but in my opinion the firmer it is the more likely it is to completely open and therefore the less leaking you should experience.

    I wouldn’t say the mooncup lightened my period or gave me a reduction in cramps. The main selling point of it in my opinion is that it does give you a great feeling of freedom. I trust the cup enough to not need pads with it, and haven’t had any problems with it. Since it is firm it helps to wet the cup with some water in order to insert it.

    Overall, if you are considering it, definitely buy it!!!

    It was my first cup, bought one at 17 and used it for four years before losing it (honestly no idea where it’s gone, my room swallowed it). Cost €30 in boots, and they’re the only brand really available in Ireland (in shops). Grand. Ish. I mean, I’m never going back to tampons, cups all the way, but I’ll probably move on from mooncup.

    Despite my best efforts, it continually leaked. I always wore a pad with it. I did have trouble with the stem for a few cycles, cut it shorter but it was still too long, eventually cut it nearly totally off, was fine since then. Never had much difficulty removing and inserting, sometimes would fail to insert properly and would feel it so I’d just try again…

    Never bothered by the bloody messy aspect of it, it’s not a big deal.

    So yeah, bottom line, menstrual cups are great but mooncup leaked for me.

    When I started using cups, I bought one Mooncup and one Ladycup. After a few months of testing them both, I settled with the Ladycup for comfort reasons. I found the Mooncup to be too stiff, especially the rim, which made the removal of the cup painful.

    It works, sort of, a little, if you don’t mind that it leaks. I have done my research, trimmed the stem, learned how to check that it’s fully open after insertion, don’t wear it to high up etc I can’t get the hang of it. It’s useless for sleeping with (or lying down), because then it migrates upwards and then sits too high, causing it to leak a lot. During the day, the leak is usually a light dribble. I can’t help but feel that if you count up constantly needing to walk around with tissue paper in one’s underwear to catch the small leaks, and the washing detergent and water it takes to wash underwear after the big leaks, then is it really that much more eco-friendly? And in South Africa, it certainly is not cheap. I am sorry I spent good money on it.

    This was the first menstrual cup I tried and I used it for several years despite finding it extremely uncomfortable as I was unaware of other models.

    Cons: the stem stuck out and even when cut off completely the stub rubbed and irritated my skin, it leaked badly so maxi pads were needed, it was too long for my cervix and would fall out on its own, it was hard to clean the ridges and holes.

    Pros: easy to insert and it pops open easily, easy to remove. Have since moved to another brand in a short length for low cervixes which has eliminated most of these problems. Customer service friendly and helpful to some extent but I was never advised that I might need a shorter product.

    It’s ok but it leaks, I’ve tried both sizes and both leak, the stem was very painful you have to remove it but I find it easy to remove as you pinch it to stop the suction. I’m going to try another make. Defo better then tampons tho! Just not the right make for me.

    The moon cup for me was the first one I tried I didn’t really know about them until I was shopping in boots and asked someone behind the counter what it was she it explained it to me and I bought on .All I can say is it’s one of the best things I’ve ever bought. It sits perfectly for me, I don’t have to worry to much when I’m at work unlike pads were I had to change them every 2-3hours because of having a heavy flow. I also have the contraceptive implant so my periods are a bit of a nightmare and can last a long time meaning if I was to keep buying pads it would cost me a fortune where as the moon cup just keeps going and going and although at the beginning I thought it was a bit pricey in the long run its has saved me so much. I don’t panic about going to the toilet and running out of pads. Cleaning it is so easy run it under a tap and its all clear. If I use a public loo and have to empty it then I wipe it with tissue until I get home to clean it. All in all although at the beginning I was a little worried of leaks and having to remove it from myself but after about a year of using it I love it! Amazing!
