Which ovulation test should I trust

Raegan
Not sure if this has happened to anyone, but if so, maybe you can give me some advice.
On cycle day 9 I got a flashy smile using clearblue easy digital ovulation tests and a peak using my clearblue easy fertility monitor. 
On cycle day 10, I got a peak using the monitor and still flashing smile with the clearblue easy ovulation test. I also used first response ovulation digital and got a no.
On cycle day 11, I got a high reading with my monitor, flashing smile with CBE digital and a no with first response.
On cycle day 13, I got a low reading with the monitor, flashing smile with CBE digital and a no with first response.
Finally on day 12, I got my solid smile with CBE digital and still a no with first response.
Is one ovulation kit more reliable than the other? Which one should I trust?
Thank you.
