Ovulation question . please help!

I have been taking the clear blue advanced opks this past week and they have been the blinking smiley face for 3 or 4 days. I ran out of them and so now I don't know if I ever got my peak day.  Normally I can feel a sharp pain in my overies when I ovulate but I never felt a big sharp pain. I could feel a little bit of twinges and flutters but not the normal sharp pain. Do you think I skipped ovulating this month? Or do you think that it just wasn't as painful as usual? I'm so confused. Please help .
