What does this look like

Hey ladies! Just curious on your thoughts.

My period is supposed to start any day now. I’ve been spotting for about 4 days. Today when I went to the bathroom and wiped. I had this weird tissue like discharge in toilet paper. I looked in toilet and there seemed to be a blood clot it looked like. So I wiped again then had blood on the toilet paper. Does this seem normal? Could it be my period or possibly pregnancy?
