Easy @ home vs Clearblue advanced

Hi everyone!

My husband and I are ttc, I’ve been using the clear blue advanced ovulation tests and felt their results were always a bit off. Example it would go right to peak two days after my period then read high later in the cycle. I started using the easy @home brand with the pre mom app and scanning then on the app. It’s super easy and it give a number and a result. Today’s was “low .31” but to compare I’ve been using the clear blue digital and it read “high” is it common for these two tests to be so different?
