Welcome to ehealthforum,
Pregnancy chances are possible if there has been a condom failure and if you were during your fertile days at the time of intercourse. The bleeding that you experienced after taking ECP could be the withdrawal bleeding that usually occurs within 5-7 days of taking the ECP. The ECP works if taken within 72 hours of unprotected intercourse, and may not work if taken later than 72 hours. Since the pills contain high dosage of hormones, these can disrupt the normal hormonal and period pattern causing period/bleeding abnormalities and appearance of new symptoms (that can at times mimic pregnancy symptoms). You can get false negative results with urine pregnancy tests done very early in pregnancy, as the kits are calibrated ones, so unless the hormone levels in urine reach a certain level, they do not show positive results. Urine pregnancy test kits usually start showing positive results after about 20 days post-conception (roughly corresponding to about 1 week after your missed/altered periods). The test should always be done on early morning first urine sample to get accurate results (pregnancy hormone HCG is believed to be in highest concentration in this sample, and you should avoid lot of fluid intake and caffeinated beverages in the night before taking the test). Wait and watch for your next periods which can be delayed. Look out for development of any other new symptoms if pregnancy is suspected. If pregnancy is suspected, or if you miss your periods, or if you have abnormal periods, 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).
