Chemical pregnancy?

I know these test are known for false positives, however. I am 6 days late, first test was 1/2 with a faint positive, second test was this AM. Faint positive in the time frame, and one test I did with water just to check for a false positive. I posted a pic of the test and my bbt chart which didn’t show ovulation but now I’m not sure if it was right. As my temps are increasing now, after I had two days of very light pink spotting. 🤷🏽‍♀️ just looking for some other eyes and thoughts.
