My hopes are way up.

Yesterday a.m I woke up and decided to take a test (16 dpo) and got a vvvvvf positive. 1st pic. So I got all excited and decided to take 2 today in the a.m, one of them being digital (17 dpo) and they were both negative. 2nd and 3rd pic. Maybe my levels just haven't risen enough to darken the line? Or maybe I just had a false positive? All advice would be appreciated.😓
