How do I know if I have a lower cervix?

Betcha never been asked your cervix height… but this is really important when using a menstrual cup! Knowing your cervix height will help you determine whether you need a Model 0, Model 1 or Model 2.


HOW TO MEASURE THE LENGTH OF YOUR CERVIX…

  • Find a comfortable position that will allow you to easily reach your cervix. Try sitting on the toilet, putting one leg up on the edge of the bathtub or squatting.
  • Make sure to wash your hands with soap and water.
  • Insert your index finger into your vagina and slide it upward until you feel your cervix. Your cervix is the shape of a small doughnut and it feels a bit like the tip of your nose.
  • Take note of how far your finger goes inside the vagina when you reach the cervix. It is important to consider the ‘knuckle rule’.

The Knuckle Rule

Low Cervix

If your fingertip can feel your cervix at the first knuckle or first bend in your finger inside your vagina, you have a low cervix. While our Model 0 is meant for a lower cervix, if you find your cervix at the first knuckle point, our UltuCup Model 0 may be too long to fit your needs. We recommend the UltuCup Model 0 if your fingertip can reach the cervix between the first knuckle and middle knuckle.

Medium Cervix

If your fingertip can feel your cervix when your 2nd knuckle is inside your vagina, or roughly half way up your finger, you have a medium or average height cervix. All model sizes are an option depending on age and if you have given birth vaginally or by C-section.

High Cervix

If your fingertip can feel your cervix when more than your 2nd or 3rd knuckle is inside the vagina or can barely reach your cervix, you have a high cervix. We recommend UltuCup Model 1 or Model 2 depending on age and if you have given birth vaginally or by C-section.
