Could this the beginning of a bfp?

I took two tests yesterday evening, both had vvvfl’s. I took this test with fmu today(picture below) and the line was a little bit bolder. Then I took a test a few hours later and nothing was there really. Any thoughts? Do hcg levels vary throughout the day? I think I’m around 8-9 dpo. I have symptoms but they could also be pms symptoms. I know these tests can leave indents even in the time frame so I don’t really trust them. All vfl’s I’ve gotten have been within the 3 minutes. I can’t tell if there’s any color to the line in this picture. Thanks for your opinions!
