Is pregnancy possible despite taking an emergency contraceptive pill after unprotected intercourse?
Patient: I had unprotected sex with my b.f on 4th of this month i took the pill within 3 hours but there is still no sign of withdrawal bleeding, my period date is 17 of the month, i'm concerned as there is no withdrawal bleeding happen, it's been more than 10 days,  is it there any chances of getting pregnant? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  As you have taken emergency contraceptive pill within 3 hours of unprotected intercourse the possibility of pregnancy is less. Usually after taking the emergency contraceptive pill withdrawal bleeding can be seen in around 7 to 10 days. But the onset of withdrawal bleeding after taking emergency contraceptive pill  may depend on which stage of the menstrual cycle  you have taken the tablet. As you have taken the tablet in the second half of the cycle sometimes onset of the withdrawal bleeding may be delayed. So, better to wait for 3 to 4 days. Even after that if you do not get withdrawal bleeding better to go for urine pregnancy test once.  Hope I have answered your query. Let me know if I can assist you further.
