Same here! 😞 AF was due 11/01 and showed today. 2 days early

Sounds like you ovulated early. It happens but you can ovulate right after Af. That’s why I don’t wait so long to test during my cycle I start testing the day Af goes away. Most women don’t know it, but you can ovulate early and miss it by waiting so many days past Af

I think I need to fine tune when I ovulate or start using OPK’s cause according to this app before I logged the start of this new cycle my fertile window was from 13-19 and now it says 12-18. And when you think about it that’s a big difference when you have a 24 hour window.
