menstrual like cramps while jogging

Question
I noticed you answered a similar question, but I too suffer from the same menstrual like debhilitating cramps.  I am 19, 5'7, and 120 lbs.  I can do all other cardio activities, am in excellent shape, and have strong abnominal muscles.  Yet, when I run about 20 minutes in these cramps start to occur.  I do not eat before I run, and have even talked to my doctors about this.  Their suggestions have not proved helpful.  Do you have any thoughts on this matter?

Answer
Hi Lauren
I don't have a solid answer for you other than what i mentioned others.Everybody is different so i understand if that info doesn't apply to you.I do know as a general rule running does help considerably.I would do a google search for info plus contact some running clubs,runnersworld.com,runningtimes.com,new york roadrunners club,letsrun.com.They all have message boards and perhaps,and perhaps some of the individuals will have the same situation.

All the best
