Error on digital test?

Kristy • Married the love of my life🤵🏻👰🏻4/21/18. Lost our angel baby at 11 weeks👼🏻 12/6/18. Had my rainbow baby boy👶🏻 3/27/20. Lost our 2nd angel baby boy at 21W3D 6/3/2022 👼🏻. Pregnant with rainbow baby #2.

I took a Clearblue digital test this morning and it says not pregnant but the book symbol and the smart countdown bar are seen faintly in the background. I’ve never seen that before. Should I get another one?
