OPKs and how they work for you

I watch my ovulation like a hawk. I started taking tests a few days ago, dead negative. Today the line appeared right away but was lighter than the control line. I took a lot of tests today because I know at some point I’ll get the positive. I also know, I’ll probably get an even darker line tomorrow. So, couple of questions,

Do you think I should BD tonight or wait to see the line get darker, as it usually always does or

BD tonight anyway just in case. I feel like iffy on things because I tried for my recent daughter for 27 months before taking clomid. And my way of thinking didn’t really work. (BDing while the test was positive but not positive positive. Anyone follow? Lol

Here’s my tests right now

How do OPks work for you???

Thanks for the feedback
