So confused!!

Veronica • I`m 30 & happily married since July 2014. Baby #1 born August 31, 2016 & #2 born May 7, 2019!
So I'm pretty sure I ovulated last week. I even got the whole "ovulating soon" & "peak day" alerts, (I also temp and chart confirmed) but today when I logged in my calendar is showing I'm on my last fertile day..wth?!
