would this be fertile cm? or something else?

i’m 27 days late for my period.

i have had discharge similar to this (not quite as much) quite a few times last month. varying from just one time, to lasting 2 days.

today i thought i finally started my period, just to go to the restroom at work and find my panties are covered in this. no exaggeration. and then when i get home from work there’s even more !
