8 days late then spotting?

All week I had light cramps, and all symptoms. But no signs of blood. I went a total for 7 full days with nothing till. I got waken up in the middle of my sleep to some weird cramps. I decided to go see at 2:34 A.M. I whipped, boom I have light pink blood. Which is in the photo! Then I got middle cramps. I decided to go to the bathroom and check around 4 A.M. I now have a mix of dark brown blood and pink. No, red blood. I’ve taken three test this week. My first one was a negative. I waited a few more days, got a vvvvlf. Decided to take another one yesterday morning. I got another vvvvlf, hard to see. But a handful of my friends see it too. I don’t know if it’s because I used clearblue.

What should I do? What do you think about my blood? Is this my period or implantation bleeding?
