OPK testing time?!

Hello ladies! 💕
This is my first month using opk and I'm on cycle day 8 tomorrow so I'm supposed to start opk testing. I read somewhere that between 12-2pm is the best time to test but unfortunately I'm at work then 😕 does it really matter what time I test? The package says it doesn't but I wanna see what's work for y'all!
