FF has given me crosshairs. Does it look like I O'd when it says I did? Glow sets my O day at cd19.  I have been taking OPKs and they were getting darker (but not positive) up until cd19 and then extremely light the next day and continue to be light. The last week I've had some inconsistent waking times and I feel like it may have thrown off the pattern of temps. I do know that I've woken up feeling extremely overheated the past 4 or so days. Anyone else have a chart that looks similar, any confirmation of O?
