Implantation bleeding?

Britney

I am 7 dpo. Last night I had light pink spotting and cramping yesterday. Today it's more brown and more cramping. Not enough to be in my underwear and after wiping a couple times it's gone until later. Could this be implantation bleeding? With my first baby I didnt bleed until I was 6 weeks. I'm always on time for my period and it's way to early for af.
