Dealing with a low cervix

It is important to remember that even when your cervix sits very low, the vagina still has extra depth available to it. When your cervix lowers during menstruation, the walls of the vagina bend in with it, and when it lifts back up, they do too.  This means that the space above/behind the cervix is deeper when your cervix is low than it would be when it sits higher.


If you find this hard to picture, find yourself a toilet roll (or imagine one), put it in a sock, so that one end of the roll is almost (but not quite) in the toe. The toilet roll is really only tehre to give some stiffness to the sides of the sock and make the next bit easier, but could equate to the band of muscles at the beginning of your vagina. Now, imagine that your cervix is the toe of your sock (easier to do if your socks have holes, :-P). Push the toe of the sock down into the toilet roll, so it sits inside the tube. The sock will now be runing up the sides of the toilet roll and then down into the centre...in an M shape. If only the very tip of the sock is your cervix, you can see how ehen it moves up and down the walls (rest of the sock) move up with it. This is will let you wear a cup. Yay!


So now we know where the cup will sit...around your cervix, with your cervix inside the cup. This means it will be taking up space in the cup, so you need to think about how much capacity you might lose. A very small cup might not suit you if your cervix is going to fill it up. So, how do you add capacity? There are 3 ways. 1) You can make the cup longer...but that will just mean it sits further behind the cervix, so you won't gain that much space inside the cup...hmmm. 2) You can use a wider cup. This is important, as your cup needs to be wide enough to fit around your cervix comfortably. You might find that if your cervix and cup are too similar in diametre they get a little too cozy. This can make it very difficult to get the cup to unseal. So, if in doubt, and if at all possible, it's probably best to to err on the side of wider. 3) choose a large capacity cup shape. Narrow bodied cups (femme, mooncup, keeper) are great for forming a seal but they have very low capacities for their size. A hoop skirt design is larger capacity, but may put pressure on your bladder. The closer the cup shape is to a cylinder shape, the higher the capacity (narrow bodied cups are a cone, while hoop skirt cups can be more of a tube with a base - a cone's volume is 1/3 that of a cylinder of the same length and width, so you can see how you quickly gain capacity by making the sides straighter).


In summary... If you have a very low cervix (or just really want that slightly-longer-than-you-should-wear cup) get a wider, hoop skirt shaped cup that can sit with your cervix inside it. Just be aware that you will lose some capacity, and you may need to be a bit more picky on texture, printing (inside and out), and material firmness.
