Has anyone ovulated a week early?! Please comment

Sara
I am so confused. I usually ovulate cd 18/19. This month I got positive opks cd 11&12. Af isn't due until the 24th. Idk if I should assume Af will arrive the 24th or earlier. My luteal phase is usually 10-11 days so if it arrives the 24th then my luteal phase would be so long
