Implantation bleeding maybe?

So i just went to the bathroom and noticed two very faint almost didnt see them pink spots in my panties. I know my cycles well enough to know i am not about to start seeing as if i was it would be a constant light flow if it even started light which it never does so i know that isnt it. My question is could the two light pink spots be implantation bleeding? 4 days from AF based off glow.
