Confused on ovulation tests, please help!

Okay so here are my ovulation tests beginning from top to bottom and the bottom one is today, as of glow stated the first ones I took were supposed to be my "most" fertile days based on what glow was telling me, now the second to last one was yesterday and that was my last and least fertile day and that test is darkest and took another one today and that's dark too...I'm not sure if the ones I took today and yesterday are "LH surge"?  So confused ​
