So confused

I took this test (even though it was only 3 dpo this cycle) because something didn’t feel right with my last period, i had absolutely no cramps or pains which I always get and it was on and off never really a proper flow, and truthfully something is definitely different with me. I took the picture in the time frame but after so much over analysing and for my own sanity I threw the test away. However I’ve just looked at the picture again and need a second opinion of if it’s a definite but faint line or indent of some sort.
