I have been having pain too when I am ovulating.....
Yes, I usually have severe lower abdominal pain when I ovulate too......One time (before I realized what it was) I thought I was having an appendicitis! LOL!
Everytime I ovulated...I would know it! It use to be so bad I had to lay down for a couple of hours until the pain subsided. It happened like everyother month for me, but it was nice in a sense because I knew why it was happening. It almost felt like a really bad side-stitch or something. But that's when I got pregnant, even though I was in so much pain, I made sure me and my hubby didn't miss the oppurtunity! lol. =)
