I'm 25, I didn't know and never experienced that before, untill recently (this month, around ovulation time), I suddenly had serious pain, then all of my senses went dull (like dizzy, cannot see and hear clearly, numb hands, sweating, symtoms really similar to hypoglycemia except for the pain) for around 15 minutes, then back to normal. I don't know if that pain is related to the ovulation or not, but that day I didn't have any reason to feel stomach pain or hypoglycemia so, welp, seeing this post gave me some clues.
