So how do you know if you have a high cervix?

Firstly read our guide on "how to measure your cervical height"  Next, if you can feel your cervix between your 2nd and 3rd knuckle or can barely reach your cervix, you have a high cervix and this cup the Juju model 3 is suitable or you. 

As finger length varies from person to person, a more accurate measure of cervical positions involves performing this same measure and against a ruler. This will produce a more precise measure of vaginal length or cervical height. 

STEP 1: Whilst standing, insert your finger until you can feel your cervix. Take note of the position on your finger where it protrudes from the vaginal opening.

STEP 2: Using a ruler, measure the distance from the tip of your finger to the exit point on your finger.

STEP 3: Check this measurement against the JuJu Cups sizing to make sure you have the cup that suits your cervical position. Model 3 = 78mm including stem, 58mm excluding stem

Many people with a high cervix can still successfully use shorter cups however for some people, their cup may sit higher in the vaginal canal and be more difficult to remove.  The Model 4 JuJu Cup is not recommended for people with a high cervix as this is a short cup and removal of this cup may be difficult.


Why would your cervix move during your menstrual cycle?

For some people, their cervix is almost always high and for others, almost always low.  However, if your cervix does move around a bit, that's normal too! As the lining of the uterus thickens during your menstrual cycle, the uterus expands and can double in size and weight. This extra weight coupled with the increased size of the uterus can push the cervix lower prior to and during menstruation. Then, as the lining of the uterus is shed during menstruation, the uterus will start to return to its original size and the cervix may move higher.
