any chance where she would conceive ?

Hi,
Welcome to ehealthforum,
If she has taken the emergency contraceptive within 48 hours of unprotected intercourse, it should help her in preventing pregnancy (provided you were not sexually active without protection after taking it). Since the emergency contraceptives contain high doses of hormones, these can disrupt the normal hormonal and period pattern causing period/bleeding abnormalities and also result in symptoms mimicking pregnancy. The bleeding that she had after few days of taking emergency contraception could be the withdrawal bleeding that usually occurs within 5-7 days of taking the emergency contraception. If you had been sexually active again, chances of pregnancy are possible due to pre-cum as pullout/withdrawal method is associated with highest failures (pre-cum/pre-ejaculatory fluid is known to contain sperms and no man can be 100% sure that pre-cum/pre-ejaculatory fluid did not leak out during vaginal penetration). Wait and watch for her next periods which can be delayed (to arrive at the expected period date, count the usual menstrual cycle length starting with first day of her withdrawal bleed). She should visit her doctor/gynecologist for further evaluation if periods are missed or abnormal, or if she suspects chances of pregnancy, or if she develops any new symptoms suggestive of pregnancy. If pregnancy gets ruled out and if you intend to remain sexually active, you should consider getting her started on suitable regular birth control measures to be protected (after her periods). She should be regular with birth control use as instructed. Avoid having unprotected sexual contact and avoid repeated use of emergency contraception.
Take care.
