5 weeks and spotting brown

So I’m currently 5 weeks and I don’t have my first appointment until Tuesday. I started spotting brown in the last like hour ( only see it when I wipe). I also haven’t really had cramping. I took another test just to make sure the line isn’t getting lighter (which it’s not I’ll post it below). But my doctors is closed today and tomorrow so I’m not sure if I should wait or if I should go to ER just incase.
