TTC with ClearBlue Digital

Tiffany • Married💍 Mommy of a handsome rainbow prince! Matthias mommy loves you! 7.5.2019 🤱🏻💙🌈👶🏻
Hello everyone. I'm TTC for baby #1 and I just started using clearblue digital ovulation tests
I tested yesterday and the test said there was an error with the test and to try again. I was at work for the rest of the day so I didn't test again. 
Today I tested for the second time and got the same result. Is it clear blue or me??? 
HELP!!!
