Ovulation test

Charlene • 1 👼🏻angel 1👶 baby girl and pregnant 🤰 with baby number 2

Hey guys so I’m new to this. I’m a little confused as I’ve never done these before. So I only just came off my period yesterday and thought I’d take a ovulation test thinking I won’t see a blur line or anything. But nope theirs a faint line and I’m a little confused. Am I already in my ovulation window now??? Can anyone who has been through this to let me know so I know what I need to do
