When I have a blockage, I go from a relatively flat tummy to looking like I am 7 months pregnant in a matter of an hour or so. I have incredible pain, no bowel sounds, no bowel movements, no gas, sometimes I am nauseaus. If you are still having bowel movements, it isn't a complete blockage, it could still be a partial blockage though. Are you having an increase in pain? A blockage can be very serious, if you are in doubt, please call your doctor.
