I really need some opinions...🤔

I took 4 tests that showed faint lines indicating positive results, followed by a dr visit where they said it was negative. Then I went home and got 2 more positive results, one of which was digital. This morning another digital said negative, and so did a 3rd this evening. All my positives have occurred in the evenings. Should I be concerned or am I really truly pregnant??? This app says I'm 4 weeks 2 days, the pregnancy test read pregnant 1-2. Which means I would be very early in the pregnancy as well. I'm so torn and don't know what to think!!
