Expert answer:
Well basically you suffer from a dyspepsia associated with constipation (signal that your digestive tract is sick and inefficient) and suffers from premenstrual tension. You need to treat your dyspepsia (food and medication changes if necessary) and premenstrual tension (contraceptive, exercise and symptomatic medications) and control your bowel (healthy, balanced diet with high fiber foods, plenty of fluids and regular exercise).
