please help!

Brittanie • Mommy of a beautiful 4yr old girl and I am pregnant with another baby girl due February 2018 💕 couldn't be happier! 👶🏼
I'm supposed to ovulate tomorrow according to glow. I don't have fertile cm that I know of but I think I did around the 9/30. Do my tests seem to be getting lighter? Do you think my tests on 9/30 are dark enough to be positive?
