Menstrual cups are gaining popularity among women as an alternative to sanitary pads during their periods. While it may be challenging to use a menstrual cup for the first time, once you get the hang of it, you’ll find it to be an environmentally friendly and cost-effective option.

With the growing interest in menstrual cups, many women are unsure about how to choose the right size. Don’t worry; we’re here to help!

1What sizes do menstrual cups come in?

Most brands in the market today offer two sizes to choose from. However, some brands provide three to four, or even up to ten different sizes for women experiencing their first period.

Small size: Recommended for women under 30 who haven’t given birth vaginally (may have given birth via C-section) or those with a smaller build, which is typical for most Vietnamese women.
Large size: Recommended for women over 30 who have given birth vaginally or those with a larger pelvic bone structure.

Size is just as important as the material and other safety factors when it comes to menstrual cups. If the size is incorrect, you may struggle to insert the cup, and it might leak during use.

2How to choose the right menstrual cup for you

Here are some factors to consider when choosing a menstrual cup:

Design

One factor often overlooked by women when choosing a menstrual cup is selecting a design that is suitable for Vietnamese women. It’s important to pay attention to the product’s dimensions and specifications to ensure a comfortable and successful experience.

Imported menstrual cups may not always be the best fit for Vietnamese women due to differences in body proportions. A cup that is too large can cause psychological stress and even affect the safety of the user.

Look for cups with a longer or rounder shape, as these tend to fit snugly and prevent leaks. Additionally, avoid cups with extremely small or large rims—small rims may not seal properly, while large rims can be difficult to insert and unfold. The thickness of the cup should also be moderate; too thick, and it won’t fold easily, too thin, and it may not unfold properly.

Choosing a menstrual cup based on design

Consider choosing a cup that comes with a sterilizing cup, as this will make it easier to clean during use.

Size

As mentioned, menstrual cups typically come in two sizes, and you can choose the right one based on your age, physical condition, and whether you’ve given birth.

Specifically, the small size measures 42mm x 47mm, while the large size measures 47mm x 52mm.

If you’re new to menstrual cups, it’s best to start with a smaller size to ensure a more comfortable experience.

Elasticity

High-quality menstrual cups are usually made from 100% silicone and are rigorously tested by international pharmaceutical regulatory agencies. A good menstrual cup should have the right balance of softness and elasticity.

Softer cups tend to have better elasticity and are more comfortable to insert, but they can be challenging to remove and may not seal as effectively, leading to leaks. Firmer cups, on the other hand, seal well and are less likely to leak, but they may feel slightly uncomfortable during insertion and removal.

Air holes

Look for a menstrual cup with air holes that aren’t too low, as this will allow the cup to hold more fluid and require less frequent changes.

Stem type

Some menstrual cups come with a stem or grip at the base of the cup to help with insertion and removal. There are several types of stems available:

Ring stem – A stem that forms a ring shape when bent.
Flat stem – Flat like a piece of paper.
Ball stem – A small ball-shaped grip.
Hollow stem – A hollow tube.
Firm stem – A sturdy, firm stem.

The stem is not a necessary feature, and if you prefer, you can carefully cut it off with a sharp knife.

3Things to keep in mind when choosing a menstrual cup

Here are four key considerations when choosing a menstrual cup: size, stem control, color, and safety certification.

Comfort

Many women prefer softer menstrual cups because they exert less pressure on the vaginal walls and are easier to insert and remove. To test the elasticity and softness of a cup, squeeze it gently. A good cup should provide comfort and not cause any pain or discomfort.

Stem control

When trying a menstrual cup for the first time, opt for a stem that is non-slip and easy to grip. If the stem is too long, you can trim it to a comfortable length to prevent it from rubbing against your clothes.

Stem control

Color

Menstrual cups come in a variety of colors, including clear, white, green, pink, yellow, orange, purple, and brown. If you have a history of skin irritation, it’s best to stick with a clear, uncolored cup.

Color considerations

Safety certification

Lastly, safety certification is a must-have for any menstrual cup. Look for cups made from medical-grade silicone, free from harsh chemicals, and certified by a reputable health organization.

Safety certification

Now you know how to choose the right size menstrual cup for a comfortable, convenient, and environmentally friendly period experience. So, make the switch from sanitary pads to a menstrual cup today!

Frequently asked questions

There are a few key factors to consider when choosing the right size menstrual cup. First, take into account your body type and cervix height. If you have a heavier flow, a larger cup might be more suitable, whereas a smaller cup is ideal for lighter flows. It’s also important to consider your pelvic floor strength and whether you’ve given birth, as these can impact the comfort and ease of use.

The position of your cervix can impact how well a menstrual cup fits and functions. If your cervix is low, a shorter cup might be more comfortable, while a longer cup might be needed if your cervix is higher. Getting the right fit ensures the cup doesn’t put pressure on your cervix and provides a comfortable, leak-free experience.

Measuring your cervix height is simple. Wash your hands and find a comfortable position, then gently insert your finger into your vagina. Feel for your cervix; it will feel firm and a bit like the tip of your nose. Once you’ve located it, measure the distance between your cervix and the entrance of your vagina using your finger as a guide.

If you experience a heavy flow, opting for a larger menstrual cup is generally a good idea. Larger cups have a higher fluid capacity, which means you won’t need to empty it as frequently. However, comfort is also key, so ensure the cup you choose suits your body type and cervix height, too.

Yes, it’s worth considering the firmness of the cup, as well as the stem and grip design. Firmer cups are easier to insert and remove, while softer cups might be more comfortable for those with sensitive bladders or who are very active. The stem and grip should be comfortable and easy to grip to ensure hassle-free removal.
