Cambiar de otras marcas de copas menstruales a MeLuna

Lamentamos que tu última taza no te haya funcionado, ¡pero estamos muy emocionados de que nos hayas encontrado!

MeLuna ofrece una copa menstrual altamente personalizable con muchas opciones de tamaño y longitud

Si vienes aquí, es probable que hayas probado primero una marca que solo ofrece dos tamaños de copa. La primera marca que estuvo ampliamente disponible fue Diva Cup. Muchas de las siguientes marcas como Lunette, Lena, Saalt, etc. siguieron el sistema establecido por las copas menstruales Diva.

La mayoría de ellos están designados como tamaños pre-bebé y post-bebé.

Para que sea más fácil encontrar tu talla MeLuna, hemos incluido la marca de la competencia más común, Diva, en nuestra línea aquí:

Estamos usando la copa Diva 1 y 2 en esta ilustración simplemente porque la mayoría de las otras marcas de dos copas que siguieron, modelaron su tamaño a partir de la copa Diva y son similares o incluso idénticas en diámetro.

En otras palabras, marcas como Saalt, Lunette y Lena tienen tamaños casi idénticos en cuanto a diámetro. Por lo tanto, hemos etiquetado los vasos Diva de esta línea como "marca genérica de 2 tamaños" porque se aplicará a muchos.

La mayoría de las marcas de dos tamaños siguen el modelo de la marca Diva Cup y tendrán un diámetro similar.

¿Está bien su diámetro actual pero la copa es demasiado larga?

Si su diámetro actual parece funcionar bien pero la copa sobresale o le resulta incómoda en la entrada vaginal, puede ser una excelente candidata para una copa de cuello uterino bajo. Conoce más sobre ellos aquí .

En general, recomendamos aumentar una talla si vas a cambiar a un shorty. Por ejemplo, viniendo de una Diva 2 que es demasiado larga, tu mejor opción puede ser la Shorty XL, ya que es significativamente más corta y al mismo tiempo un poco más ancha.

Una excelente manera de obtener toda la información necesaria para hacernos una buena recomendación es completar nuestro "Cuestionario de cambio de marca".

Algunos consejos para cambiar de marca de copa menstrual

Si ha usado su copa menstrual de otra marca durante bastante tiempo y en general funcionó bien, no recomendamos bajar de talla incluso si nuestras recomendaciones generales para nuevas usuarias de copa lo sugieren.

Por ejemplo, si tuviste menos de 2 partos vaginales, la sugerencia de nuevo usuario para MeLuna sería la talla Grande. Si has usado la Diva talla 2 durante varios años y quieres cambiar, una MeLuna grande tendría un diámetro ligeramente más pequeño que tu copa actual.

Un MeLuna XL podría ser una mejor opción en ese caso para evitar fugas debido a un diámetro insuficiente. El diámetro insuficiente es la causa más común de fugas. Puedes encontrar más información en nuestra entrada de blog .

Don't Love Your Current Menstrual Cup?

Your current cup can help you find a better fit. Whatever isn’t working now can point you toward what needs to change. With more choices in diameter, height, firmness, and handles, MeLuna gives you more ways to get the fit right. See how your current brand compares below.

Why People Switch to MeLuna

A cup can be well made and still be the wrong fit for your body.

Meet MeLuna: Made in Germany, Designed for a Better Fit.
Manufactured in Germany from medical-grade thermoplastic elastomer (TPE), MeLuna USA menstrual cups are made specifically for MeLuna USA, an independent, woman-owned small business in Texas. Our cups are FDA-registered and offer 168 possible configurations.
With multiple diameters, cup lengths, firmness options, and handle styles, MeLuna gives you more ways to find a comfortable, reliable fit whether you're switching from another brand or choosing your first menstrual cup.
MeLuna offers more ways to customize your cup than any other brand.

Four diameters

Choose from Small, Medium, Large, and XL instead of trying to make one of only two sizes work.

Options for low, average, and high cervix

Choose Shorty for a low cervix or Standard for an average cervix. For a high cervix, pair a Ring Handle with a Nupsi extension for added reach.

Two firmness options

Classic works for many users. Sport is firmer and resists compression from strong pelvic floor muscles.

Three handle styles

Choose a Ball, Ring, or Stem based on how much grip and added reach you prefer.

Start with diameter, then consider cervix height

Diameter often matters most for preventing leaks. Cup height affects comfort and accessibility. A cup that is too long may create pressure, sit too low, or feel uncomfortable. A cup with too small a diameter may leak or slide down. A cup that sits high may be easier to reach with a Ring Handle and Nupsi extension.

Compare MeLuna Diameters

This image shows how the four MeLuna diameters compare with Diva Cup sizes. Use it as a general diameter reference when comparing MeLuna with other brands.

MeLuna Size Dimensions at a Glance

MeLuna Standard and Shorty cups come in the same four diameters. Shorty changes the cup height, not the diameter.

MeLuna Size	Diameter	Standard Height	Shorty Height
Small	38 mm	45 mm	35 mm
Medium	41 mm	48 mm	38 mm
Large	44 mm	51 mm	41 mm
XL	47 mm	56 mm	44 mm

Large

Diameter: 44 mm
Standard Height: 51 mm
Shorty Height: 41 mm

XL

When comparing brands, start with diameter, then compare cup height based on cervix height and fit needs.

Their Old Cup Wasn't Quite Right Either

These customers came to MeLuna after another cup was too long, caused pressure, leaked, struggled during exercise, or simply wasn't comfortable.

★★★★★

Super Comfy!! Can't feel it at all

“I've been using this new cup for a week so far and it's super comfy. I've tried the regular Diva cup and that's way too long when I'm on my period. My previous go-to was a regular Fleurcup, but even that could be too long some days, and the silicone started harboring bacteria after about 8 years. This one is the perfect size for me! It's taken a little getting used to with the stiffer rim, but I get it now. The useable volume seems lower than the other two cups for me, so I need to empty it a bit sooner. I don't have a heavy flow.”

Product: Low Cervix MeLuna Menstrual Cup, Ball Handle, Shorty, Classic

★★★★★

Love it!

“I have had a Diva Cup for years and when the plastic started to degrade, I thought I'd try something new. The Diva Cup was great but I hoped something slightly smaller would be more comfortable. So far, this cup is perfect. Due to the shorter length and how the plastic changes shape in heat, I have had less problems with pressure on my bladder, etc. and I am loving it!”

Product: MeLuna Menstrual Cup, Ring Handle, Classic

★★★★★

Better results

“I switched from diva cup to MeLuna sport as I kept having leaks. After researching I found out the leaks could have been due to having a too flexible cup. This one is indeed less flexible which has reduced any leaks especially during exercise.”

Product: MeLuna Menstrual Cup, Stem Handle, Sport

★★★★★

Meluna regular menstrual cup

“This cup was my second try at a menstrual cup. My first was a saalt soft. I feel like I got the hang of this one faster. I switched because I thought I was sensitive or allergic to the other cup. It got very itchy after wearing for a couple of hours. This one didn't. Yay! It's pretty comfortable and worth the learning curve.”

Product: MeLuna Menstrual Cup, Stem Handle, Classic

MeLuna is made from TPE, not silicone

Some people who experience discomfort with a silicone menstrual cup prefer trying a cup made from a different material. MeLuna cups are made from medical-grade thermoplastic elastomer, commonly called TPE.

Individual experiences vary. Itching, pain, or irritation can have several causes. Stop using any product that causes discomfort and speak with a qualified healthcare professional when symptoms continue.

Diva Cup Too Long or Uncomfortable?

If your Diva Cup feels too long, the right replacement depends on how much shorter you need it. A smaller MeLuna Standard may already offer a shorter cup body, while MeLuna Shorty provides a more substantial reduction in length. Use the chart above to compare options without overlooking the diameter needed for a reliable seal.

Saalt Cup Difficult to Insert, Open, or Remove?

If your Saalt Cup isn’t working quite right, switching to a different material and cup design may make a difference. MeLuna cups are made from medical-grade thermoplastic elastomer (TPE), which responds to body warmth and adapts to your contours.

MeLuna Classic is our first recommendation for most people switching from Saalt. It offers a balance of flexibility and reliable opening. Its more flexible body can also be compressed to help release the seal during removal. If you need additional resistance to compression during exercise or strong pelvic floor engagement, MeLuna Sport offers a firmer alternative, though it can be harder to remove.

With four diameters and Standard or Shorty heights, you can adjust your fit without automatically moving to a firmer cup.

Flex Cup Leaking?

A frequent complaint about Flex Cups is leaking. If you’ve experienced this problem, you may want to consider a different cup design. MeLuna menstrual cups feature a one-piece TPE construction without the moving pull-tab mechanism used by Flex. Our four diameter options also give you more flexibility to find a secure, comfortable fit. And if you originally chose Flex because you wanted a handle that’s easy to reach, MeLuna’s Stem and Ring options are worth exploring.

Pixie Cup Causing Cervix Pain or Cramping?

Casco Bay Molding has made menstrual cups sold under several brand names. If you're replacing a Casco Cup, Rael, Athena Club, or UltuCup, use the model names and side-by-side photographs below to compare the designs. Cup names alone don't tell you the rim diameter.

These comparisons do not establish that every private-label version uses an identical mold.

Looking for Rael Size 2 or Athena Club Size Two? The corresponding Casco Mid 2 (47 mm) is no longer offered by Casco, Rael, or Athena Club. Remaining old stock may occasionally turn up, but there is no currently available retail version we can direct you to.

Which MeLuna Cup Should You Consider?

Your current cup gives you useful information. The problem you are experiencing can help identify which feature to change.

Your current cup feels too long

Consider MeLuna Shorty for a low cervix.
Compare cup body length, not only total length with the handle.
A shorter cup may reduce poking or pressure.

Learn About Low Cervix Cups

Your cup is difficult to reach

A Standard cup may suit an average or high cervix.
A Ring Handle provides a secure grip.
A Nupsi extension can add reach for a high cervix.

Explore High Cervix Cups

Your current cup leaks

Confirm that the cup is fully open.
Consider whether you need a larger diameter.
Strong pelvic floor muscles may compress a cup that is too flexible.

Troubleshoot Cup Leaks

Your cup leaks during exercise

Consider MeLuna Sport.
Its firmer material resists compression during high-impact movement.
Sport can be harder to fold and remove than Classic.

What to Expect When Switching Menstrual Cup Brands

MeLuna is made from medical-grade TPE rather than silicone. The material may feel and behave differently from the cup you currently use. A short adjustment period is normal when changing cup shapes, firmness, or materials.

You May Not Feel a Strong Pop

Some silicone cups create a noticeable popping sensation when they open. A MeLuna cup may unfold without producing the same sensation.

Gently feel around the base to check that the cup has unfolded and is positioned comfortably.

A cup does not need to make a sound or create a strong pop to work correctly.

The Cup May Take On an Oval Shape

MeLuna cups are made from thermoplastic elastomer, or TPE. TPE responds to heat, including your natural body heat, and can gradually adapt to your body's shape during wear.

Because the vaginal canal is naturally more compressed than round, you may notice that your cup has taken on an oval or slightly asymmetrical shape when you remove it. This is normal.

Once your MeLuna has adapted to this shape, simply cooling the cup will not necessarily make it round again. It may remain oval until you wear it again, when body heat allows the material to adapt again. If you want to return the cup to a rounder shape, the heat used when boiling it for disinfection can help reshape the TPE.

An oval cup does not mean the cup is defective, and it does not cause leaking. The cup is sealing inside a vaginal canal that is itself compressed rather than perfectly round. If you are experiencing leaks, cup diameter and fit are more important factors to investigate than whether the cup looks round after removal.

Your Usual Fold May Feel Different

A fold that worked with your previous cup may behave differently with MeLuna. You may need to adjust the fold, insertion angle, or the point where you allow the cup to open.

Give yourself a few practice attempts before deciding whether the cup is the wrong fit.

Persistent Leaks Need Troubleshooting

Early leaks may result from placement, incomplete unfolding, cervix position, or cup size. Continued leaks may indicate that you need a different diameter, height, or firmness.

Your Previous Cup Size Does Not Equal a MeLuna Size

Cup size labels are not standardized between brands. A Small, Medium, or Large from another brand does not correspond to the same MeLuna size label.

MeLuna offers more size and fit combinations, including four diameters and two cup heights, so we use our own sizing system. When switching brands, compare the actual cup dimensions rather than the size name.

Start with diameter, then consider height and firmness.

Extra Fit Support Is Included

Switching brands can raise questions, especially when your new cup differs in shape, material, or firmness. Every eligible MeLuna cup includes our MeLuna USA Guarantee, so you can contact me for fit help and have additional options if a different MeLuna configuration is recommended.
