Extremely confused

So I’m very confused and honestly upset! I am 13dpo today, period is due tomorrow however I usually have spotting the day before, so far nothing. I took a test Wednesday and Thursday 9/9 and 9/10, 9/10 had a faint line and it dried like this (picture- ignore dates) well I haven’t tested at all since then as I was on vacation so I just retested and got this (second picture) if it was a viable pregnancy I would expect this to be so much darker? It’s barely even there. Please give me your thoughts I’m really praying this is our month.
