Round 3 of Letrazole

On my 3rd cycle of Letrazole. The past 2 cycles I had a definite positive OPK on CD18, so I expected it again. Surprise! I got a positive today! CD14.

I'm a lil confused with Glow, though. Last cycle, O was around 7/31. But somehow, when I entered info after CD1 this cycle, it had changed my O date in the calendar to like 4 days later.

Fingers crossed third time's the charm!
