Update to my vvvfl... I need help

**UPDATE**

So at 7am I took two more tests and they didn't show positive right away or at least that is could see. I timed them for 5 mind and too the pics of them when I had a Mon left and it doesn't seem like its gotten darker almost like it is getting lighter tell me what you guys think. Should I wait a few days to take another one or should I wait till like 8/8:30 and see if I just needed to wait longer to let the HCG levels be a little stronger?

P.S I took at least four tests yesterday and they all came back the same so idk if I should've taken a test earlier next time or is it possible to get more than two false positives in a row?
