OK, I got my period on July 7th . It was heavy like usual and normal the first 2 days... but now all I keep seeing is dark dark brown discharge .
I've heard it is usually old blood but I am not sure what this is
At one point it looked black almost.


Please help.

Dark blood is old blood left over from the previous menstrual flow; a sluggish menstrual flow. It makes sense that the new uterine blood should come first, then the older after. No, it could not have been black.

I understand . Its just bothering me because the first 2 days it was very normal and heavy like usual. And now its just light and dark dark brown discharge.
Every time I would look up something, it would say that it was implantation.
