help please x

Chantelle
Hi, I'm new to this, cycle one ttc. I got a what I believe is a positive OPK on sat 29th Oct (photo below) i temp as well so did I ovulate on Monday 31st? 
Only asking because I am using the clearblue advanced OPK tests as well as the strips and they are still giving me a flashing smiley face. Is it possible that my CB ovulation tests missed my LH surge? Which do people think are more reliable strips or clearblue advanced? 
These might sound like stupid questions and i apolgise if they are. Just need some help/clarification.
 
Thanks x
