Which is more important, firmness or height?

This is my second month checking it. This month has been completely different from last in everything from my temps, mucus, and everything. ​​It's been low with firm to medium. Today low and completely soft.  

  From what I've read it varies for different women.  Maybe check during AF, when you ovulate and during TWW to compare? So you'll know what your body does?  I'm not sure mine never matches up with the options Glow provides in the log. Did you see the post on CM? It shows how your cervix changes with ovulation and so on. Maybe your ovulating or going to? Sorry, I may not have been much help, I just hate when people view questions with out offering some kind of help. 

Mine too! I'm also curious...
