Period or implementation bleeding ?

Faith

Hey ladys so i have a problem that i seem to be confused about. On Saturday, I started bleeding.

But then I realized it wasn't blood, it was all brown. Which confused me Because I just got off my period two weeks ago. So the brownness that only lasted two and a half days could it be implantation bleeding? If so how long do you need to wait to test to see if you are pregnant? I swear ive had 2 symptoms the last few days.
