heaviness in my abdomen and discomfort in he morning?

Hi,
Welcome to ehealthforum,
It is difficult to comment on your symptoms without examining you. The symptoms could be suggestive of possibility of pregnancy. Wait and watch for your next periods. If you suspect to be pregnant, look out for development of any other new symptoms suggestive of pregnancy. If you suspect pregnancy, or if periods do not start within 10 days of expected period dates, or if you have altered periods, consider visiting your doctor/gynecologist at the earliest for further examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Take adequate rest. Drink plenty of water. Maintain healthy diet.
Take care.
