help please!

so AF was supposed to come on the 30th and nothing so far and took hpt on 31st and bfn, took another on 2nd and another bfn, then on the 3rd a vfl and another vfl today not darker than yesterday's but about the same. I'm not sure if I trust the faint lines even though there were ones on 2 tests, how many days late were yall when you got a dark positive or positive on a digital? cause if I don't get AF today I will be 6 days late and on cycle day 37. I really really hope I get a bfp soon!
