Is this a positive on my ovulation strip?

Trying to track my fertile window better then just going off an app!  First time trying the ovulation kit, I'm on a 29 cycle and took this strip this morning on my cycle day 12. The result looks exactly the a positive and a negative! I don't understand! 
Also if it's positive , does that mean my egg will be released in the next 24-32 hours ?
Thanks ladies!
