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

Firstly read our guide on "how to measure your cervical height"   Next if you can feel your cervix at the first bend in your finger or just inside the vaginal opening, you have a low cervix or short vaginal canal.

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: 

If your cervix or cup is sitting very low in the vaginal canal, causing bladder sensitivity or causing any discomfort, please see your GP as this may be an indication of pelvic organ prolapse

Trimming the stem

Your cup may be forced to sit lower due to your cervix location and the stem of the cup may protrude. In this case, we recommend you trim the stem of your Mermaid cup as it may cause discomfort or irritate the labia. Read our article about "trimming/removing the stem of your cup." Please only trim the stem of your cup if you are comfortable with the removal of your Mermaid at all stages of your cycle as your cervix may ‘retract’ towards the end of your cycle and be hard to reach. Only trim a small amount at a time; trimming off one node at a time then re-inserting after removing each node to check if it is at a comfortable length.

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.
