Help reading opk please!!!

Hi ladies,

I’m super confused on opk so I’m hoping you al can help! I took an opk yesterday at noon and the second line was super dark, and it was the same yesterday at 3. So of course hubby and I had sex yesterday afternoon, as well as Saturday and Friday night, just to be sure.

But today, the line was darker than yesterday, and my temp raised by .3. Can anyone help me?? Am I ovulating today or yesterday? And if we have sex tonight, is that too late?? Photo below!
