Question about CM

Ok so here’s my situation. Af is scheduled to arrive Saturday. That’s according to my apps. I’ve very irregular but past few months I’ve been between 33-37 days.

Around day 20 I had spotting. I assume ovulation spotting because it was brown with some spots of red.

Now I’m 3 days out from AF. I’ve been experiencing EWCM every time I use the bathroom. Does this mean anything?

Side note: about a week before AF arrives, my chest gets sore. It hasn’t happened yet.
