Implantation Bleeding or Period?

Sydni

My period is exactly a week late today, I have tested and all negatives. I have had cramping for most of the last 5 days. When going to the bathroom tonight, I wiped and this was on the toilet paper. Normally my periods start first pee of the morning and see Bright red. So I'm curious if this could be implantation bleeding or my period? Thank you for your advice.
