Mooncup Menstrual Cup Size B
The Mooncup is a reusable menstrual cup, around two inches long and made from soft medical grade silicone. It is worn internally a lot lower than a tampon but, while tampons and pads absorb menstrual fluid, the Mooncup collects it. This means it doesn’t cause dryness or irritation, and also that it collects far more (three times as much as a ‘super-absorbent’ tampon’!). Because the Mooncup is reusable, you only need one so it saves you money and helps the environment, too.
The Mooncup is designed to be folded and inserted into the vagina, then removed, rinsed and reinserted up to every 8 hours. A light seal is formed with your vaginal walls, allowing menstrual fluid to pass into the Mooncup without leakage or odour. This seal is released for removal, allowing you to empty the contents, rinse or wipe and reinsert. Comfortable, convenient and safe: the Mooncup can be used overnight and when travelling, swimming or exercising.
The Mooncup and MCUK are available in two sizes:‘A’ and ‘B’. Size A measures 46mm in diameter and 50mm in length. Size B measures 43 mm in diameter and 50mm in length. Both sizes have a pull stem 21mm long, which you can trim to the length that is right for you.
Sizing is based on pelvic floor tone, not menstrual flow, and it’s important to get the sizing right to get the best from your Mooncup or MCUK. Pelvic floor tone will vary according to your age, childbearing history and what sort of exercise you do. Corrective surgery to the vagina will also have implications. Check the guidelines to see which size you need:
Because vaginal and pelvic floor tones naturally reduce with age, the size ‘A’ is recommended for women aged 30 or over. The difference between the ‘A’ and the ‘B’ is only small (3mm), but it is crucial!
Size ‘A’ is also recommended for all women who have given birth vaginally, regardless of age.
Designed for young girls and women under the age of 30 who have not given birth vaginally. It may also be suitable for women over the age of 30 who have had corrective surgery to the vagina, or who are advanced in tone-maintaining activities such as yoga, dance or pilates.
