Your description of abdominal symptoms is not sufficient to make a differential diagnosis and advise you. Your gynecologist will address the lack of periods, but I recommend consulting a specialist in internal medicine for a thorough history, physical examination & any appropriate testing in order to advise you.

From what you described, you are not pregnant. Your symptoms are most like explainable by movement of gas in the intestine. It would be prudent to consult a doctor, preferably a GI doctor.
