Can someone please answer me???

me...
I'm driving myself nuts trying to find the answer. Google is no help. And I have not found anyone here that has been able to answer it. I have posted this once but I'm going crazy! 10 dpo I had a tiny spot of blood. Now 13 dpo I'm bleeding. ( not supposed to start for a couple more days ) I took my tampon out today after a few hours and there was lots of nasty brown slimy stuff on it. But my cervix is still high and soft instead of low and hard like it should be on my period
