How often do you have sex during ovulation

My first pregnancy I wasn't expecting to happen so fast lol I never tracked anything because my body was adjusting to getting off the pill. This second time around, in actually tracking. Tomorrow starts my first Green Day so I'm curious to see what all your answer are. I've been cramping since yesterday. I can actually feel myself ovulating which is different then before. It actually hurts a lot so I'm hoping I can pull off sexy time lol & yes I've been to the dr about it already :)
