Okay, so this is only my second cycle ttc and I'm still trying to get the hang out checking my cervix..  I have gotten the hang of telling if it is low/high and weather it's soft/hard.. But how the heck can you tell if it's open or closed or "medium" .. And when does it usually open?  I feel like today mine may be medium/open, but I am only in day 0/1/2 (depending on the app) of my fertile window. Would open make sense??
