What is a Menstrual Cup?
How do Menstrual Cups Work?
They collect your period blood inside your vagina
and can be worn for up to 8 hours at a time, giving
you unparalleled freedom compared with traditional period products.
Ruby Cups are made of medical-grade silicone,
making them soft and easy to use. You can reuse a Ruby Cup for up to ten years, saving around 10kg of plastic waste ending up in landfill.
Choose Your Menstrual Cup Size
When choosing your cup size, the first thing to consider is how much blood you lose during your period. This is called menstrual flow: it can be light or heavy.
If you have a light flow, you may be using small or regular tampons or pads and changing them a few times during the day.
If you have a heavy flow, you’re likely to be using super or super plus size tampons or maxi pads. You’re likely to be changing them frequently during the day and also at night.
Now you know your flow, you need to figure out if your cervix sits high or low. To find your cervix, simply slide your longest finger into your vagina. You’ll find your cervix sitting at the top of your vagina.
If your longest finger goes almost all the way into your vagina before it reaches your cervix you have a high cervix.
If your longest finger finds your cervix around the middle knuckle mark, then you have a low cervix.
Watch Hannah, one of our trainers, demonstrate how to find and measure your cervix to determine whether it sits high or low cervix. She also debunks some common myths on what affects your menstrual cup size and shares some tips.
Now you know your menstrual flow and the position of your cervix, you can use this chart to see which size Ruby Cup will work best for you.
*Note that if you have a low cervix and heavy flow, then both the small and medium size will work for you. You may need to empty your cup more often with the small. The medium sized Ruby Cup will hold more blood and need emptying less often, but you may need to trim the cup stem for comfort.
Tip: If your menstrual flow varies from the first to the last day of your period you may want to use both sizes of a cup, depending on your daily flow.

How To Use a Menstrual Cup
How To Put In A Menstrual Cup

2. Fold your cup and insert into your vagina.
3. Once inside, the cup will unfold to create a suction that keeps it well positioned and prevents leaks.
Menstrual Cup Folds
The C-fold is one of the most popular menstrual cup folds and gets its name because the point of insertion looks like a C.
1- Squeeze the sides of the cup together.
2- Fold the cup in half to make a C shape.
The 7-fold makes a smaller insertion area than the C-fold and usually ‘pops’ open easily making it a popular with beginners.
