How to measure your cervix
We created a picture guide to help you find out your cervix height and decide which size of menstrual cup fits you best!
​
Simply insert your index finger in the vagina and find where your cervix is, that feels like a donut (a circle with a hole).
Remember to always wash your hands before you insert your finger!
Use the pictures on the left as a guide to decide if you have a low (between 2-4 cm) or a high sitting cervix (more than 4 cm)!
​
If you don't feel comfortable doing that, ask your doctor to tell you if you have a high or a low cervix.
