EWCM instead of AF?

Hannah
I have had a couple different things going on this month, but perhaps the strangest has been the EWCM I've had on 7, 9, and 13 (today) DPO. I've tested a couple times, all bfn. Stared at a test for hours last night because I swore I saw something but I'm not convinced. AF was due Sunday. I had one tiny spot of brown on my undies Saturday but nothing since. CM seems to be yellowish tinted.
​Just FYI a couple other odd things: have had crazy dreams... I mean super disturbing. I'm a teacher and dreamed a student hung herself at the school. Had another that there were mounds of ticks crawling on me while I was laying in bed.  Also my cervix has been insanely high and remains that way.
