2 days late, faint line or dreaming?

Hello! We have been TTC #2 for 7 months. 2 days late and typically on time. Took multiple tests showing either evaporation lines or faint pos lines. What do you think?

Update: 4 days late, tests showing negative (first response and HCG test from my ovulation kit) and no sign of period. Taking another test in the morning but no longer visible faint lines :( I’m so sensitive to smells and nauseas all day... with my first child it was a surprise and I was 1 week late and the lines showed immediately. I’m planning to make a dr. Appointment if not period in 2 more days (6 days late) and negative still. Is that too soon?
