Opinions?

So back story, I had a d&c 8/5. Today is 4 weeks post, what do you make of these test results?

Top one was 8/27 PM, then 8/28 PM, and the bottom one is today, 9/2 afternoon.

If this is from the D&C, shouldn’t it be dropping and getting lighter at this point? Can anyone give any advice from experience? Do you think the bottom test result looks any darker? (As I’d expect it to get lighter..)
