Hello and thank you for sharing your question.
First of all, it is important to note that EC is only effective if taken correctly. For example, the second pill of Postinor 2 needs to be taken 24 hours after the first not 3 hours. So if you took the EC correctly then her period is late due to hormonal disruption.
If she did not take it correctly, then pregnancy would still be a possibility.
You will need to assess the situation in reference to those facts.
