Implantation?

Checked myself after slight cramping last night. I had thick lotion like texture cervical mucus, couple minutes later I checked my cervix and say a little bit of blood on my finger. When I wiped it was pink and only a streak. This morning I checked and now there is nothing but a little streak that is like scanty orange/pink/red, but I still have slight craning. What is this? I'm not schedule for my period until April 24. My period is never this light. And why am I slightly cramping?
​I am 8 dpo by the way.  
​I also attached a picture of the blood last night.
