Has anyone had this happen?

So I took a Clearblue Advanced opk and a Clinical Guard opk today at about 5pm and the Clearblue was a blinky smiley face but the Clinical Guard was super faint.

This is my first month using opk’s, and I’ve only been taking them for about 4 days. The Clinical Guard have not gotten any darker at all really, but the first 3 days using the Clearblue it was just the blank circle and then today the blinky smiley. I am not sure which one to go with.

My usual cycle runs around 40 days, and I am only on CD11 could I be getting ready to ovulate already? It seems early.
