How to Measure Your Cervix: A Very PACII How-To

How to Measure Your Cervix PACIIMeasuring your cervix is as glorious as it sounds. It’s the best. It’s fantastic. We promise.

Okay, we may be using alternative facts here, but it does play an important role in figuring out what menstrual cup might work the best for you. While it is just one piece of the puzzle (check out our popular quiz for the rest) it plays a major role in comfort. And comfort is one of the best parts of switching to a cup.

The basic idea is what is sometimes referred to as ‘the knuckle rule’. First knuckle: low cervix. Second knuckle: average. Third knuckle or can’t reach? high!

To better demonstrate, we decided to make a very PACII how-to. We hope you enjoy it and as always, if you have any questions, leave a comment here, on the video, in our Facebook group, or basically anywhere else you can track us down. We’ll do what we can to help!

  • I am 31 and have had 4 babies. I have the Lena cup and have tried using it twice now. I have a terrible time with it slipping down. I have to adjust it almost every hour or so but it slips down and is uncomfortable. Can anyone help me? I love the idea of a cup and really want this to work. Thanks

    • The way a cup stays in place is through creating a seal. Slippage can happen anytime a seal is broken or not made in the first place. There are many ways this can happen. Do you twist the cup after placing it as high up under your cervix as you feel comfortable? I twist mine to make sure the seal is there, or to help seal it if isn’t made yet.

      If you’ve never felt your cup seal, you may need a larger cup.

  • yeah this was a great video!
    the only thing not mentioned is prolapse!
    i think because our lifestyle isnt as active as it should be, and because women are tossed out of birth as a vessel instead of a human, most doctors miss physical symptoms of not only prolapse, but weakened muscles or diastisis!
    if you have a prolapse, that is going to push the cup around and make things wierd. obviously this video solves the problem of uterine prolapse, but the two other kinds can definitely play a role!

    i would guess if you have problems with it constantly slipping, you probably have a muscle issue / prolapse / diastisis bothering you as well.
