Ovulation test help!

Ebony

I started my period on the 18th August and finished it on the 24th. I started to test ovulation on cd8. I got the darkest the lines have been yesterday on my test but not quite a positive. I tested twice yday last around 5pm. I tested today twice and now it’s even lighter again? It is possible I missed my surge or that I haven’t even ovulated yet? As it was darker yesterday but still a neg result but now is lighter today? So confused please help 😐.

This was yesterday’s test around 5pm. Since today it’s gotten lighter again? Also I have very very pink cm/ spotting yesterday when wiping and light cramps here and there today also. Is it possible I missed my surge and I’ve already ovulated or have I not at all?
