False positive?

On Monday I took a FR with first morning urine, the test had a vvfl but was there and pink. I took another that afternoon from a different box of tests, it looked negative. I figured my urine was to diluted as it was only a 2 hour hold and it was still to early. Because I’m addicted to taking tests I took another that evening from the same box of tests I took that morning and it looked the same. I thought maybe I’ve been fooled by the faulty FR tests and decided to just take another one the next morning. So yesterday morning (Tuesday) I took 2 tests (FR) and they were very clearly positive (same urine). So I decided to take another this morning and well I was extremely thirsty throughout the night and drank 3 full bottles of water and went to the bathroom at midnight and woke up at for the day at 6 so a 6 hour hold and my test looked negative. Could it be that my intone was to diluted and It’s still to early?? I posted a picture of yesterdays test below could it be false or am I over thinking?
