Geez, in the last 10 years I always get that pain on the left (or right side) depending upon which ovary is cranking out an egg this month. It causes lower back pain and sometimes even spotting. At least it lets me know I'm still going to be regular. I NEVER was in my teens - and that made for some scary worries about unplanned babies!!
There's a medical term for this, but I can't remember it at the moment.
Any other ladies experience the mid-month ovulation "pain"?
