Some mornings 1minute after waking up. I get an abdominal cramp (as if you need to go to the bathroom) that resolves alone after about 30 seconds?

Irritability reflex. This may be a mild manifestation of an irritability of the bowel as a responsive reflex To awakening. If you're not experiencing urgent loose bowel movements as a result and are fine the rest of the time, I wouldn't be concerned about this symptom. For further concerns consult a gastroenterologist.
