pls help, how long after peak test did you ovulate and how did you know?

Miss

What is your experiece with ovulation? I got a smiley face/peak yesterday morning and today morning we BD, how long after a peak ovulation test does one ovulate, how do you feel it or know? 

Last night I had cramps as if someone was pulling something out of my stomach, not that bad but you get the idea, today the crap is still there but not as bad. Do you think I've ovulated?
