Opk results faint?

First (black bkgrnd) is at 12pm the last one with (bathroom bkgrnd) was taken at 6 pm. My CM was watery and the new poke from the dollar store do not say the "as dark or darker" it just says if their a line. I have a very fast ovulation time it happens only a couple days after AF and since it doesn't just..stop..I'm guessing on when my AF usually stops this week it was super fast only lasting 4-5 days..idk what to think I'm so confused it seems to be lighter then the earlier one so I'm not sure if I missed it? I'm cycle day 8..what do you think??
