Choosing A Menstrual Cup
It can seem very daunting choosing a menstrual cup there are so many choices and variable.  The female anatomy is very accommodating and many people can use any cup without problems however like shoes some fit your feet a bit better than others.  Have a read through our article below and then once you know your personal requirements use our menstrual cup comparison chart to find your perfect cup.

The key things to consider are:
Height of Cervix
Firmness of the Cup
Menstrual Flow

Height of cervix.
This is one of the most important things to consider as it helps determine how much room you have for your cup length and if you should have a stem or should trim it for comfort. Your cervix is at the end of your vagina and is the part that dilaltes in labour. Your menstrual cup will sit below your cervix or in some cases your cervix will sit just inside the cup. Your cup should push against your vaginal walls creating a seal and preventing leaks. You can of course buy a cup without knowing the height of your cervix but if you do know it will help get a better fit. Your cervix can change in position and height throughout your cycle so it’s best to measure your cervical height during your period. Checking your cervix height is somewhat messy but once you know the height it’s not something you should need to check again unless you have any gynalogical changes.

How to measure
Check while standing up so that it’s most accurate, lying down can alter the position.
Do not check before, during or after sexual intercourse as the cervix can change position and your vagina can also change length and width.
Wash your hands and ideally have short and clean nails, you don’t want any unnecessary scratches!
A popular way is to raise one leg on the toilet seat.Insert your middle finger until you can feel your cervix. It will feel soft and squishy and you’ll possibly find a dimple in the middle a bit like a donut.

As a rough guide you have a:
Low cervix if you can reach it by the first kuckle on your finger (the first bend at the top of your finger)
Middle cervix if you reach it on your second knuckle or middle of your finger.
High cervix if you can’t reach it or you have almost all your finger inside.

Firmness of Cup
Menstrual Cups vary in firmness.
Firmer cups are better if you do a lot of exercise and/or have strong pelvic floor muscles as they pop open easier and won't collapse under the pressure of your internal muscles.  We have a full separate article where we discuss all options for "Exercise & Reusable Sanitary Products" However some people find firmer cups not as comfortable and can put pressue on their bladder making it harder to empty your bladder. An example of a firm cup is the Meluna Sport.
Softer cups are better for sensitive bladders and are easier to insert however they can be harder to pop open into position especially if you have strong muscles. They are not considered the best option for sporty people and younger girls who tend to have a stronger pelvic floor. The very softest cup we've found is the &Sisters Nudie Cup. 

If you have a heavier flow you'll need a bigger capacity cup. This is often more important than choosing a cup based on your age. Many cups suggest that people under 30 without children need a smaller capacity cup however if you have a heavy flow ignore this and go for the larger cup
If you've never used a tampon and haven't been sexually active then i'd start with a smaller cup until you get the hang of it. It's the same advice given when you first start with tampons to use the mini size. Meluna make some lovely small sizes ideal if this is you.

A retroverted uterus is a uterus that tilts forwards rather than backwards. It is often called a tilted uterus. most women don't find it has any impact on which menstrual product they choose but if you have both a low cervix and a retroverted uterus then you may need a specific product which we are happy to help you with.
