When did I ovulate?

A. • Wife • Fur Momma 🐱 🐶 • Baby Momma 🎀 Girl Mom • 🇨🇦

I did my <a href="https://glowing.com/glow-fertility-program">IUI</a> on the 25th (Tuesday) in the morning and on my fertility friend app it says I ovulated on the 25th. But from what I’m reading on here it says I ovulated on Monday the 24th?? And I’m 1DPO on the 25th.. or am I reading this wrong.

Isn’t ovulation the day before 3 risen temps..so that again would make ovulation date the 25th? Opinions please.. did I miss it??
