for safer side i gave her i pill within 2 hours

Hi,
Welcome to ehealthforum,
Semen or pre-cum coming in contact with vagina can result in pregnancy especially if she was during her fertile days/ovulation time at the time of the sexual contact. If she has taken the emergency contraception within 24-48 hours of the unprotected sexual intercourse, it should work in preventing pregnancy (provided you were not sexually active without protection after taking it). Withdrawal bleeding usually occurs within 5-7 days of taking the emergency contraceptive indicating that the pill has worked (which could be the cause for the bleeding she experienced after taking the ECP). Since the emergency contraceptives contain high doses of hormones, these can disrupt the normal hormonal and period pattern. Wait and watch for her next periods which can be delayed. If pregnancy is suspected, she should consider visiting her 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).
If pregnancy gets ruled out, and if you are not ready for pregnancy but intend to remain sexually active, she should consider visiting her gynecologist to get 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 repeat use of ECP.
Take care.
