a difference between pregnancy and ovulation discharge?

Hi,
Welcome to ehealthforum,
The discharge during ovulation time is usually increased, clear, egg white in consistency in appearance, stretchy etc. Discharge during pregnancy need not be clear, egg white like or stretchy, rather it can be increased and altered (but without associated symptoms suggestive of infection). Wait and watch for your periods. Look out for development of any new symptoms if pregnancy is suspected. 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).
Take care.
