Glow says I'm 4dpo, where as FF says 3. I felt good about timing this month until FF gave me cross hairs a day later than I assumed it would. The inconsistent temps are due to the fact that I am a nurse and work night shift. I always temp after at least 5 hours of sleep though. What do you think is correct? I think I O'd on cd12. But I usually trust FF. I'm confused this cycle. I didn't do OPKs either this cycle which would've helped with the inconsistencies in the apps! Thanks for your time!
