Hello dear
Understand your concern
Yes Postinor cause delay in the period as it cause hormonal imbalance (high chance as you took two times in week).
Hormonal imbalance occur due to high progesterone in the postinor 2.
High progesterone prolong the second phase of cycle and cause delay in period by 5-7 days.
So do not worry, your period will come in next 4-5 days.
But if period will be delayed by 10-12 day then possibility of pregnancy as postinor 2 has some failure rate (5-10 %). In long delay go for pregnancy confirmation by HPT and or blood HCG.
Hope this may help you
Best regards
