If you have the right size menstrual cup, it sits comfortably and you won't experience any leaks. A well-fitting cup is therefore important for a carefree menstruation. In this blog, we will explain how to choose the right size.

Why the right size is important?

The right size menstrual cup prevents discomfort and leaks. If the cup is too small, it can move or not seal properly, which causes leaks. A cup that's too large can be difficult to insert and may cause pain. With the right size, you barely feel the cup, and it provides up to 12 hours of protection.

How to determine the right menstruation cup size?

To choose the right size, pay attention to three things:

Age and Childbirth: Are you under 30 and have not had given birth naturally? Then a smaller size is usually suitable. Are you over 30 or have you had given birth naturally? Then a larger size is often better.

Pelvic Floor Muscles: Strong muscles, for example from sports or yoga, might mean that you need a smaller cup. Weaker muscles might require a larger cup.

Menstruation Flow: For light bleeding, a smaller cup works well. If you have a heavy menstruation, it's better to opt for a larger cup.

Size Options

Size S: For teenagers or young girls who are just starting their menstruation.

Size M: For women under 30 who have not had given birth naturally.

Size L: For women over 30 or women who have given birth vaginally (possibly multiple times).

Unsure whether to choose size M or L? We recommend trying size M first.

What to consider?

Finding the perfect menstrual cup is incredibly important for both comfort and reliability. Here are 4 tips to help guide your choice:

1. Position of the cervix

First, check the position of your cervix. A low cervix requires a shorter cup; a higher cervix might be better suited to a longer one. You can check this yourself during menstruation: if you can easily find your cervix, it's likely low.

2. Amount of Menstruation

Also look at how heavy your menstruation is. A lighter flow can be well-managed with a smaller cup, but a heavier flow might require a larger cup because it holds more.

3. Personal Fit and Comfort

Everyone is different, so what works for your friend may not work for you. It may be necessary to try a few sizes to find the best fit, especially if you're active or exercise a lot.

4. Test period

Take your time to try out a new size. It might be wise to start with two different sizes and see which one feels best over the course of your entire cycle.

Frequently asked questions about cup sizes

What if I'm unsure between two sizes?  

If you're unsure between size M and L, we recommend starting with size M. This size is usually more comfortable if you haven't had a vaginal delivery.

Can I use different sizes during my menstruation?

Yes, some women use a larger size during heavy days and a smaller size on lighter days.

What if the cup doesn't fit well?  

If the cup leaks or feels uncomfortable, you might need a different size. Try another size or contact a Bamboozy advisor.

Choosing the right menstrual cup size may require some experimentation. Start with the recommended size based on your age and childbirth experience. If the cup doesn't fit well, try another size.

If in doubt, contact Bamboozy or consult a gynecologist for personalized advice. Ultimately, it's all about comfort and what works best for your body.
