I’m confused 😐 please help!

So this morning I posted this

it’s been my absolute darkest opk so far. All of my others have been barely visible on the test line.

Just now I took this (bottom one). The line is barely visible again! The one above was from this morning.

Considering all of my opks have been looking like the bottom one or lighter, does it look like I surged this morning?

Also, today I had a definite egg white super stretchy CM - whereas all week I’ve been pretty dry and sticky - yesterday was stretchy but cloudy. Today all clear and super stretchy.

I’ve found this opk thing a little bit hard to gauge because sometimes even my control lines are lighter than what I see others if you posting.

Any thoughts ladies?
