Stress incontinence: You're describing stress incontinence which is most common in women who've delivered several children vaginally. There are no medications for this. Kegel exercises are the best non-invasive way to fix this situation. Check out http://www.Mayoclinic.Com/health/kegel-exercises/wo00119 for details. Also, bladder training & scheduled toileting are useful for any incontinence. Go see ur doc for evaluat.
