I would like to start with saying that I wish to only write reviews and I am not comparing cups because I think it is a matter of preference and if you love a cup for whatever reason, you will make it work.

Things that matter the most to me when choosing a cup are the height of your cervix – only if it is extremely low, otherwise most of the cups will work; the material the cup is made from – personally I prefer to only use medical grade silicone because the percentage of allergic reactions to it is almost non-existent; I prefer transparent cups with exception, because we don’t need to add more unnecessary ingredients. I like to use a cup from a brand and not a cheap Chinese one that is sold online because there is no way to know the quality of these materials. I also like to know that the cup has passed FDA tests and/or European health requirements.  

I heard about the Moon Cup 7 years ago. I had my first baby and waited for my period to come back before I ordered it and I was so excited to try it out!

A bit of information about the Moon Cup:

There is the one made in the UK and the USA one is called “Keeper”. It is made from medical grade silicone and feels like a good quality menstrual cup.  

There are 2 sizes: 

Size A is if you are 30 years old and over OR if you have had a baby. Its capacity is 29.3ml, the diameter is 46mm, the length is 50mm and the stem is 21mm, so the total length is 71mm.

Size B is if you are under 30 years old and you have never had a baby. Its capacity is 28.8ml, the diameter is 43mm, the length is 50mm and the stem is 21mm, so the total length is 71mm.

At the base where the stem is, there are 2 rings for better grip.

During my first use, I felt it all the time. I felt it against my vaginal walls and it was very sore. Removing it was quite a mission due to its chunky rim. I tried it for 2 more cycles and on different days of my period. With great sorrow, I had to stop using it as it was just too painful and I found myself stressing out from using it.

Years later after my second birth and when I heard about another menstrual cup, I realized that the Moon Cup is stiff and with time I have come to learn that I prefer softer cups because they are more gentle on my vaginal environment.

I think that being one of the first cups on the market, it manages to keep its popularity, perhaps due to being a quality cup with an FDA registration.

Some words about soft vs. stiff cups: 

There is a tendency to think that soft cups are more difficult to pop open. I have learned with time that on different days of my period, different folds and stress are also some of the factors that lead to the popping open issue.

I have tried many cups and I still am. Yes, I am donating my body for the sake of the reviews. Some are soft, while some are stiff and I have needed to make some adjustments with all of them.

** Please note that these reviews are based on my own experience and are therefore my own opinion. I would also like to mention that we are all shaped differently and if something didn’t work well for me it doesn’t mean that it won’t work for you.
