Opk help first ttc

Mia

This is my first month ttc and using opk

This was my result Sunday night

Than this was Monday evening

And this is today

This is how many times we had sex

Am I doing this right or should I have had sex more times ? Does the negative I got today mean I’m not ovulating anymore just need some clarification on everything please or if anybody could message me directly and explain everything better thanks in advance
