spotting, anyone else?

Sarah
I had spotting which doc said was just implantation bleeding around the 4 weeks mark. Since then I haven't had any notable spotting or bleeding and I am now 6w1d. This early morning I woke up to bright red blood with a small clot when I wiped, not enough to soak into clothing. I feel like this happened with my first pregnancy and all was fine but I can remember. Has anyone experienced this? Since this morning I've only noticed a brown colored discharge and only when I go to the bathroom. Also, no cramping other than the mild stretching cramping.
