For those who use opks

Did you find your ovulation day was different than what your app predicted and if so by how many days?

Yes! Sometimes by 1 day and sometimes 2-3. The apps use a formula that doesn't apply to everyone.

@eatanazurecrayon thank you. We're you ovulating before or after your app predicted?

Usually before. The month we got pregnancy it was 3 days before the app predicted! If you use the clear blue advanced ones they pick up when the oestrogen starts to rise so you get a couple days warning!
