Hi, Thanks for the query. The possibility of pregnancy is less as you have taken emergency contraceptive pill. To get accurate result from urine pregnancy test kit: -You have to do the test preferably one week after expected date of periods. -With early morning midstream urine sample. -And immediate appearance of the result to be considered not delayed one. You should not take tablets to induce abortion without doctor s consultation. Ultrasound is needed to confirm the intrauterine pregnancy and to estimate the gestational age. Then according to the report, with your doctor s advice you can go for abortion. After taking the pills it may take around 24 to 36 hours for the onset of bleeding. Take care.
