when your cervix goes really low down (like you can reach it with a finger) what’s that about? does it happen just before a period? Does it go randomly up amd down all the time?

fertility-matters:

*Typically* the cervix will be lower, firmer, and more closed when you are in an infertile part of your menstrual cycle, and higher, softer, and more open when you are in the fertile times of your cycle, and it will typically get a bit higher/more open as it prepares for a bleed.
