Faint Positive To a negative

I am 4 days late. I posted the first two pictures last night. Many of you commented and said you thought it was positive. This morning I took a digital and it said “not pregnant”. I opened the digital and found two lines on the strip (3rd picture). I’m so confused. Has this happened to anyone else. I’ve been so let down so many times that I don’t want to give myself false hopes. I’m so tired of this endless cycle of pregnancy tests.
