Do these tests look lighter?

The third test from the bottom looks so dark but maybe my urine was more concentrated? I had a hcg draw at 4 weeks 1 day that was 783 and then at 4 weeks 3 days that was 2014. I have a history of early miscarriage so I am a nervous wreck. The bottom 2 tests seem to ge getting lighter… should I call my dr and ask for another draw? I am 4 weeks 5 days today.
