Positive opk??...

Tracie • I'm 25. Had a miscarriage and d&c 5-1 waited 1 cycle and I'm pregnant again with my rainbow EDD 3-11 ❤️🌈
This is my first cycle after miscarriage and first time using opks. I'm on cd18. This isn't positive yet right? Hoping it gets darker tomorrow... These are kind of hard to read 😩
