How to measure your cervix:
With clean hands, insert 1–2 fingers into your vaginal canal. Feel for the opening of your cervix, which feels similar to soft cartilage (some compare to the tip of a nose but softer). Your cervix will have a tiny hole in the center. Reaching your cervix with your finger inserted to the 1st knuckle = low, 2nd knuckle = medium, 3rd knuckle = high. If your cervix height is low to medium, we recommend you choose the Saalt Small. If your cervix height is medium to high, we recommend you choose the Saalt Regular.
Your cervix can change position throughout your ovulation cycle. Because your cervix may descend lower into the vaginal canal or continue to sit higher during your period, it's best to check your cervix height once your period starts.
