Someone please read I need some input...

I started bleeding yesterday, it's been super heavy and I'm in so much pain, cramping and lower back ache... and today the second day of said spotting/bleeding...when I wipe it's blood with CLEAR slippery/Slimy discharge mixed in (I noticed because it was like shiny almost lol) what I would call raw Egg whites for sure, mixed with the blood....what on earth is my body doing?? Can this much heavy bleeding seriously be from ovulating??? Also I was suppose to start my period in 7 days not yesterday lol please help any input would be wonderfull...should I consider this my period? Wait a few days and see?? Ughh...
