OPK - Cleablue 'O' but rise in LH easy@home

[JS5]

Abit confused. Please see images below.
Today CD20. Got rise in LH on easy@home strip but clearblue showing 'O'. I thought clearblue is supposed to be more sensitive?

Previous cycle, I had my first rise (which led to peak), on CD20 also, similar score (found this quite interesting!). I had a static smile on my clearblue test same day, so was expecting the same today.

Any thoughts on this?

Btw I've done a few tests using clearblue this cycle. As I read somewhere it uses the first test in the cycle as baseline

I had the same last month, the clearblue digital totally missed my ovulation, luckily I was also using the strips so I caught it.

I just scrapped using the digital ones as I much prefer the strips where you can see the line progression with your own eyes (and a hell of a lot cheaper too!)

Thanks for responding. I got my static smile this morning and a continuing rise in LH :)

I guess I'll be relying on the easy@home strips moving forward x
