TMI this is just weird!?

As of today I’m 3 days late on my period. Cramps occasionally. I’m always on time with AF. Maybe even a day early sometimes. I’ve had spotting 2 weeks ago. I know you’re supposed to have a low/hard cervix during your period, but mine is high between soft and firm. It’s also closed. Just now I went to the bathroom there was some egg white cm... very odd. Anyone want to chime in on as to what this might be??? ****UPDATE**** I took an EPT 4 days ago and it was BFN. My cm has changed from watery to egg white.
