Didn't wanna read'n'leave, but I have no personal experience, so this is from Wikipedia

Your bleeding will eventually taper to a normal period and then to spotting. The color of the flow will go from bright red, to brown to a yellow or whitish color as your uterus heals. It is normal to see an increase in amount or a darkening of the color of the blood if you do something more strenuous or move around more. This may be an indication that you need to take it easy.
