Faint second line?

6 days late (which is very abnormal for me), breast tenderness and cramping a little the past few days, but not nearly as bad as I do leading up to af. Called doctor and they said to wait and keep retesting, then call again on Monday with update! Taken these tests first thing in the morning over the past three days... do y’all see the super faint line or am I imagining things??

Thanks, ladies!

This was taken Wednesday, but looks totally negative.. I couldn’t see the second line I thought I saw in others!
