The cervix
What do we need to know about the cervix?
The cervix is the bottommost part of the uterus and it connects the vagina and uterus. It produces mucus which changes its consistency during the period. For example during the ovulation it gets thinner and allows the sperm to enter the uterus. During the pregnancy, the cervical plug is formed on the cervix. This plug is apparent even during the first weeks of pregnancy and it keeps the baby inside the uterus.
There is a canal in the cervix, which is usually very thin. The mucus membrane of the cervix doesn't separate itself during the period, contrary to the endometrium. It is covered in longitudinal mucosal algae which fit each other and close the opening perfectly. This membrane is called endocervix and protects the uterus, fallopian tubes, and abdomen from foreign particles or pathogens. The cervix opens a little bit during the period to allow the blood flow away from your body, but it still prevents the foreign particles from entering. Therefore it is impossible for the blood to flow back in during the sleep, or even the headstand.
Where is the cervix?
The cervix is usually placed 7.5 to 12 cm deep in your vagina. It is semi-spherical with a small hole in the middle. The hole changes into the line after natural childbirth (see picture). Apart from the mucus consistency it is also able to change its position. It is really important to know the exact location of your cervix in order to be able to position the cup correctly. Some women are able to place the cup directly onto the cervix, other gets the underbelly pains if they do so. It is really important to try and find your way.
Before exploring the position of your cervix, wash your hands thoroughly. Do not use any cosmetic products that are not specifically designed as a femine intimate wash.
It is possible to reach the cervix in any body position. The best position seems to be sitting (at the edge of the bed) or squatting. Insert your longest finger (most commonly index or middle finger) into your vagina and you should feel the semi-spherical widening with the hole inside. Some women compare the cervix to the donut. During the ovulation the cervix is usually placed higher and it is softer, while outside the ovulation and during the period it is lower and harder.
Now we know where the cervix is. How does this information help to choose the right cup?
The deeper you inserted the finger, the higher your cervix is (see picture). You can even measure the length of your finger.
If the cervix is within the 5 cm away from vaginal orifice it is the low cervix. You can use our smaller size if your cervix is 4.5 cm or higher. We also recommend inserting the cup inside out (stem facing inside) to reduce its size even more. If the distance between the vaginal orifice and the cervix is less than 4.5 cm, it is necessary to choose the cup designed specifically for the low cervix.
If the distance between the vaginal orifice and the cervix is more than 5 cm you can use all designs of the cup. In the case of the middle cervix (about two phalanxes) difficulties with inserting the cup deep enough (the stem isn't all way in) may occur. In such cases, feel free to shorten the stem or use the inside out method of insertion. You may also use the Evolution design which allows the stem to be pushed inside into the desired position without a need of shortening it.
In the case of a high cervix (three phalanxes), the stem needn’t be shortened. The cup should be in an upright position relative to the cervix to prevent the leaking around it (see picture).
Someday you may be surprised by a sudden leak, even if you have done everything exactly as countless times before. This may be caused by the cervix changing its position. This is a natural part of the life of every woman. Adjust the position of the cup to your cervix.
Why should I know where my cervix is?
Women should be aware of their bodies. On a more practical note, you can keep track of your window with the help of the cervix. It is also important during pregnancy. If the cervix goes down, it may release the cervical plug and premature childbirth may start. And last but not least, it is crucial knowledge to choose the right size of the cup.
We urge you to not underestimate the regular check-ups at your gynecologists who make regular swabs of your cervix. Do not forget that cervical cancer is the second most common cancer with women. If you notice changes in the cervix or if you experience blood discharges, post-coital bleeding, or pains in the underbelly, do not underestimate these warning signs and seek the advice of your gynecologist.
