its lighter because the concentration of your HCG is a little less concentrated. Did you go to the bathroom a bit earlier or early to take the test? The dark line is the control, it doesnt need the HCG to turn pink, just fluid......the other line MUST have the pregnancy hormone present to change, no matter how faint. If you where not producing that hormone you would not see a second line. Congrats!!!
