Confused about ovulation day

I have been TTC

Anyway after a few months and nothing happening I got some ovulation tests...

Glow kept telling me my ovulation day was August 12th so, in two days... apparently.

I started testing Tuesday... yesterday (Thursday) I got the darker line.. and today it’s faint again. So I’m assuming it’s negative. What a disappointment!

I’ve been doing it wrong all these months.

So my ovulation day is over and I had no idea... no hope for me this month I guess.

I still don’t understand ovulation but I know it’s not in two days like Glow keeps telling me 😡😡😡😡😡😡 I’m frustrated!
