Just need a bit of help...

Sooo I took a digital ovulation test yesterday and today and got a smiley. Yay!! This means I’m in my fertile days right? My first smiley after a year so this is new to me.

But now what does this mean and how will I be able to pin point my ovulation day.

Also I’ve been experiencing alot of abdominal pain just on the one side so I’m guessing its coz of ovulation but idk.

Please help 🥺
