Hello,
Thanks for using health care magic

it is unlikely that you could be pregnant. Emergency contraceptive pills are highly effective when taken within the required time period (i.e. within 72 hours after the sexual intercourse).

Another reason why you can not be pregnant is that, you had sex just 5 days after you saw your menses. Unless you have a really short cycle.

Emergency contraceptive pills are hormonal pills and hormonal pills are known to create modifications in menstrual cycle. So it is less likely you are pregnant and the delay is due to the emergency pill.

Best regards
Dr Achuo
