I just started birth control last night, fell asleep and woke up the next morning to upper abdominal pain, diarrhea, & sob...Is this a side effect?

Probably not. These are not usual side effect symptoms of oral contraceptives. It is more likely that your intestinal disorder is due to another cause. That being said, certain people have unusual (but not serious) reactions to any number of drugs...Sort of falls into the saying "everyone is different". I would suggest continuing your pills as they are most likely not the cause of these symptoms.
