Please can someone help :)

Hello! I’m supposed to have my peak day today so i have taken a clear blue ovulation test in the morning like usual. This is my first time using it instead of the strips and i may have done it wrong but i did follow the instructions. The screen says negative but when i pull the strip out it has two quite strong lines. Is this because it’s a blue ink one or could the test be wrong? Thanks for any help 🥹
