Wrong ovulation test?

[Katielouise111]

Hey ladies, I’m new to ovulation testing and was wondering if anyone else has had a ‘peak’ day on the premom app that wasn’t your highest one cycle?

Hi, I use it as a place to compare the tests as I don't trust the number. Don't know if that's because I take the pictures wrong (but have to otherwise my camera doesn't pick up the lines)
As you can clearly see when it says I'm peaking I'm most certainly not)
I think you need to take into consideration cm and the tests themselves plus whatever else you may track,not just the number premom gives x
