Ovulation test negative?

Summer • In love with my best friend❤️ mommy to a beautiful 2 year old baby girl Anastasia Reneè🌸 and a handsome 2 month baby boy Anderson Raylen🏈

Okay so I took my first ovulation test today glow says today is my highest ovulation and its negative I'm so confused I've never tried tracking or ovulation test because with my daughter we got pregnant so fast and easy but we haven't yet so I thought I would try and now I'm a little upset can someone explain this better to me when am I supposed to test thank you 😍
