Is this normal spotting? Cause for concern?

I just found out I'm pregnant this last week and am almost 5 weeks. This morning I started having some brown spotting when I would wipe, and now this evening the color is pinkish/red. Just enough to notice when wiping, none on my underwear. Is this normal spotting or should I be concerned? I didn't have any spotting at all my last pregnancy so this is new for me. Thoughts ladies?
