Blood in my discharge?

Kas
I should be starting my period soon. I am late becayse of stress with everything going on in my family.
No I'm not pregnant I took a test, i will be taking it again this weekend I think?
Anyway, I've been cramping and having discharge. The other day there was a little bit of blood in it. Today there is a lot more than usual but not enough for an actual period and its slimy looking.
What's going on??
