I had the same thing with my second child. It was placental obruption. Meaning my placenta pulled away from the uterus wall...mine was only sight, but i would call your doctor...check it out...better safe then sorry.
Hi, I am going through the same problem now at nearly 6 week, there is nothing to worry about, If you do get concerned and it gets heaver and turns to a bright red ring your Doc. But it is ok :-)

I had that at 6 weeks just keep an eye on it make sure it doesn't turn to blood an if you get any pain straight to hospital (I'm now 29 weeks pregnant) hope this helped xx
Its just old blood. Its fine :-)
