Cervical position and CM trackers

So we have been trying for a few months now and I use cervical tracking to help determine ovulation. I almost always can feel some mild cramping and twinges and I get lots of ewcm... sorry for the tmi.

This cycle my cervix has been all over the place. It never got super soft even though I had 3 days of ewcm and it felt open all of those days. Then after my peak day it felt very soft and almost swollen and shut tight. Now it is back to firm and feeling slightly open. I know I'm probably out for this cycle :-( but I was wondering who else uses this method and if they had any advice. I do have 1 son who just turned 2 and we got pregnant with him using this method. I'm just ready for another one :-)
