9dpo cm- picture included

I know it’s still early but I just wiped and got this cm. It looks a little tan/pink to me (in the next wipe I got a pinprick size dot of red blood but no pic) I never spot before my period. Now I’m experiencing period like cramps but not as bad as usual. Could this be implantation bleeding? I thought maybe implantation happened around 6dpo due to some sharp poking sensations that took my breath away in my right lower abdomen. Is it possible to bleed 3 days later?
