Implantation

So last night (tmi alert) when I was wazing (as my daughter puts it lol) I noticed the smallest spots of blood. Like pencil tip spots. I went again about 20 minutes later And there was a little brown/dk yellow on the tp. I'm 7dpo. Is it too early? Could this even be implantation? I have been having pulling/pinching feelings all over my lower abdomen but nothing I would describe as cramping like af. I'm gonna try testing In a few days.
