Is it just me or is this strange?

Hello wonderful people, so today I got my period. Now I am on birth control, and recently thought I was pregnant. But when I got my period, my blood is dark and almost a brown color. Was the pregnancy test wrong? I take my birth control everyday, although not at the same time everyday.(I am trying to make a better habit of taking it at the same time everyday). Could this be the reason why my blood is a different color... tmi I know.
