Been ttc for 6 months, have 3 different apps that all had different peak weeks and period predictions... this month 2 of my apps actually synced up. Plus the past few months of ovulation testing I never got a dark double line, only a faint on which says is actually a negative on the ovulation tests.. so I've never known my true ovulation day. Today I got 2 dark lines and my cm is perfect egg white consistency! Yay, hopefully tonight is the magical night! Prayers 😊🤞🏻
