Any advice???

Im only 3 days late, no symptoms (pregnancy or period) what so ever. Yesterday i had some blood when i used the bathroom and only when i wiped. It was bright red/ pinkish looking color and its never that bright when i start my period. Also a little bright red blood today as well but no more. Now obviously the only way to tell is to test but what do you think?? Implantation or start of period?
