Can someone help me, ovulation question?!

I was crampy last night on my right side, sometimes sharp pains but for a few hours and this time right now is usually around when I ovulate. We are doing the sperm meets egg plan and I haven’t got a positive LH yet but ones that are really close. We had sex last night and two days then two days before that. Since I had spotting and ovulation cramps tonight am I too late to catch my egg? Will having sex tonight even matter? Or should we have sex the next three days like the plan suggests when you get a positive LH even though I haven’t got one yet? Below was my strip this morning when I got home from work! My CM is clear and stretchy with slight brown streaks
