After using OPKs last month and giving up on them because I never got a positive, I figured maybe I wasn't ovulating because I was newly off birth control pills. Then this month I've been taking them every day since AF ended to try catch it. And finally I'm almost there! I always thought that I ovulated around CD 14, but apparently I ovulate WAY later than that. Today is CD 17. Hopefully I'll get a positive by tomorrow morning meaning I'll O around CD 19/20. Praying this is our month!
