Hi,
Welcome to ehealthforum,
The spotting, increased vaginal discharge, absence of usual pre-menstrual symptoms, could indicate possibility of pregnancy. Do not depend on the appearance of typical symptoms alone to suggest possibility of pregnancy. The appearance of symptoms suggestive of pregnancy depends on how your body reacts to the changing hormonal status/levels during pregnancy. Few women do not experience any symptoms. If periods do not start within 10 days of expected period dates, or if you get abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
