1. Length
Cups come in different lengths, the cup that will work best for you wont be too long or too short. To work out which length cup you need, check the height of your cervix during menstruation (see next question for 'how to check cervix')
2. Size
Most cups come in 2 sizes:
- A smaller one for women who have a strong pelvic floor, generally under the age of 30, and have had no vaginal births.
- A larger one for women over 30, or who have given birth vaginally, or with weak pelvic floor muscles.
The Me Luna comes in 4 sizes (the Me Luna Small is the perfect size for teens or girls who have not been sexually active)
What we are wanting is for the cup to create a seal around the walls of your vagina when it has been inserted, this will prevent it from leaking.
3. Volume
Is your flow light, medium or heavy? You may choose to go with a larger cup, so that you do not have to empty it as often.
4. Firmness
This is quite important. If your cup is too soft, you run the risk of it being squished by your pelvic floor muscles, and it leaking.
The Me Luna comes in 3 different firmness's; soft, classic, and sport. The LENA is a firm cup. The Diva cup is slightly softer.
5. Material
As well as the material, either silicone or TPE, there are various different 'finishes' that a silicone cup can have. Some are glossy, some are matte, some are coloured, some have embossing, and some are smooth.
