Weirdest thing, I swear the same thing happened to me, except the whole bursting feeling. I could swear to you that I've never in my life "felt" ovulation and in fact have always secretly made fun of women who say they can LOL But, I'm on my first cycle off BCP and I had the same kind of one-sided crampy/sharp pain thing yesterday; then today my temp spiked -- I mean a serious thermal shift. So it had to have been the ovulation -- I don't even normally get cramps with AF.
I say it's totally possible that's what you felt. I say run home, don't walk, and BD.
