AF OR PREGNANCY

Amber` • Elena Reign 7/26/19💕🤱🏻

Today I "started" my period but nothing was on the pad (yes I use pads, sue me) well Everytime I whiped it was LIGHT pink like this color but lighter. But blood and pee test was negative. Could it be AF or implantation bleeding?

UPDATE: no blood is on pad nor when I whipe. It completely stopped.
