ovulation was on the 19th was i fertile on the 24th?

Hi,
Welcome to ehealthforum,
After ovulation, egg has only 24-48 hours to get fertilized. After this time it gets disintegrated. If fertile mucus is not present, sperms cannot pass through cervical canal and do survive for long time. The chances of pregnancy are minimal unless your sexual intercourse was closer to the ovulation time. Wait and watch for your next periods. Look out for development of any other 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.
