BD tomorrow?? Or wait?

Ra

I posted this in another place as well but I’m wondering if the opk section might be best. I can’t quite tell if today is positive or not or possibly just close. I’m really quite new to Opk’s so any help is appreciated!

Here is when we have currently bd’ed

And this is what flow mentioned that it is best to bd every other day for best motility

When should we bd if my line gets darker? Or was today perfect with my line?
