Hi,
Welcome to ehealthforum,
Change of bowel movements, bloating, nausea could be suggestive of possibility of pregnancy. Look out for development of any new symptoms suggestive of pregnancy. Wait and watch for your periods. If you suspect to be pregnant, or if you are having symptoms suggestive of early pregnancy, you should consider visiting your doctor/gynecologist for further evaluation/examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.
