OPK Help

Allie • Wifey 💍 27 👩🏼 girl momma of 1 💕👶🏼 Baby #2 Due May 2021🤰

Need help with my OPKs. I got almost positive OPKs on CD 7 and CD 8 (I test twice a day) but never a positive and now my strips are getting lighter everyday. Did I not ovulate this month? :( I usually ovulate around CD 15 and have never had these dark of OPKs this early on in my cycle! Any ladies have similar experiences?
