This app is way off. I have been using this app for 6+ months and still not prego. I had been using cheap ovulation sticks as well. I thought this month I would up my game and go for the Clear Blue Digital ovulation kit. According to that, my peak day is today. This app had my peak day three days ago. Hopefully this will be the month now that the correct peak days are confirmed. Used pre-seed for the first time as well. Fingers crossed. AF is due 5/4. I do not want to see its fave this month.
