Which size?

Size Table

Size is related to age and childbearing history as these can affect pelvic floor tone. Size is not related to menstrual flow.

Size Size A

Recommended for those who are 30 and over, and all who have given birth vaginally regardless of age.

Size Size B

Recommended for those under the age of 30 who have not given birth vaginally.


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 stem 21mm long, which you can trim to the length that is right for you.


I decided to try Mooncups after hearing about them on various forums. I have struggled with (and HATED) my heavy periods ever since my teens, had problems with flooding (always having to double up tampons and towels) and always suffer with a sort of nappy rash from having the vile things next to my skin for 6 days every month!!! One of the things I hated most was having to get up (messy) in the night three or four times to change!! The mooncup is EVERY bit as good as the reviews say and worth every penny it costs!!! I got it in the first time with NO problems using the C fold (there are diagrams of a couple of folds,but if they don't work for you there are others on the internet, have a google around) and after cutting the stem off completely it was so comfortable I didn't notice it was there. I didn't believe what people were saying about their periods being less painful while using the mooncup, but am completely shocked to say that this HAS been my experience and I've not managed a whole cycle without painkillers (am currently on my second cycle with mooncup). It is certainly no more difficult and no messier than using tampons, particularly if you have a heavy flow, because it never floods!! I WISH I had tried it sooner and now I have I want to shout from the rooftops about it. If you're thinking of giving it a go, DO you won't regret it!!
