What to do?

Yesterday I did a LH test that was positive. It was CD14. Today did the test again and the line was stronger. I usually ovulate CD16/17, which is tomorrow. I use Natural Cycles to track my cycle and ovulation. Hubby and I had sex last night and on Tuesday night, I’d love to do it every other day, but hubby isn’t around tomorrow. I suggested we have sex tonight again but he’s not feeling very well, bless him. So, is it possible that yesterday was enough? Or we need to have sex tonight too? Or do it on Sunday? I don’t want to miss an opportunity here.
