As if knowing your bra size wasn’t enough, now you have to know your vagina size?

Don’t panic, that’s why we’re here. Although you’d be well off with either menstrual cup size, we want to make sure you’re comfortable with your choice.

That’s why we offer two sizes (because not all vaginas are the same).

Menstrual Cup Sizes - The Cup Size Guide For Your Body and Flow

Lunette is emptied about 2-4 times a day, and can be used overnight for up to 12 hours.

You will quickly learn your own rhythm by viewing how much fluid your cup has gathered. The measuring lines outside of the cup help to monitor your flow.

Flow

Lighter flow? Model 1 might be for you.

Heavier flow? Give model 2 a go!

Age

For teens and young users, the smaller model 1 makes for easier ins and outs.

Pregnancy

For those people who have given birth out there, you can use the Lunette menstrual cup model 1 or 2. Pregnancy changes a few things down there, so firstly take into account your new cervix position (if it's low use a model 1), and secondly your new flow volume post childbirth.  

Cervix

If you have a low-sitting cervix, try the shorter model 1 for a better fit.

Lifestyle

If you're a fitness goddess with strong vaginal muscles, consider using Model 1.

Bladder

Sensitive bladder? The softer model 1 might be a match made in heaven for you.

FAQs

How do I know if my flow is heavy or light?

The dividing line between normal and heavy flow is 80 ml during your periods.

Lunette model 1:

Spotting: A drop or two of blood, not even requiring a sanitary pad though you may prefer to use one. 
Very light bleeding: Needing to change a low-absorbency tampon or pad one or two times per day, though you may prefer to change them more frequently.

Light bleeding: Needing to change a low or regular absorbency tampon or pad two or three times per day, though you may prefer to change more frequently.

Lunette model 2:

Moderate bleeding: Changing normal absorbency pad or tampon every three to four hours. 
Heavy bleeding: Needing to change a high-absorbency tampon or pad every three to four hours, though you may prefer to change more frequently.

Very heavy bleeding or Gushing: 
Protection hardly works at all. You would need to change the highest absorbency tampon or pad every hour or two.

How does the menstrual cup differ from the tampon?

Both are internal menstrual protection. A menstrual cup collects the blood and the tampon absorbs it. A tampon can be used only once whereas a menstrual cup can be used for many years.


The absorbing capacity of a tampon is given in grammes and the capacity of the menstrual cup in millilitres. One ml of menstrual blood is comparable with a gramme, so the capacity of tampons and menstrual cups are comparable. The capacity of the Lunette menstrual cup is 25 ml (model 1) and 30 ml (model 2). The absorbing capacity of a tampon is 6-18 g.
