Can someone help explain this to me?

From top to bottom 8, 9, and then 10 DPO. I know it’s early to be testing. These tests are from two different boxes. I swear I see something in person but it’s harder to see when I don’t darken the photo. My husband can’t see anything at all on the tests and it’s driving me crazy. I can see a hint of something but not enough to make me sure that it’s a definite positive. I have some symptoms of being tired, waves of nausea, and emotional, and crazy. Also sore nipples but nothing too intense. Anybody go through anything similar? Any body else have this happen and eventually get a blatant positive test?

Edit:

Here’s the original photos
