Hello dear
I understand your concern
There are two causes:
1. Side effect of the postinor 2:
It contain high progesterone and cause prolongation of second phase of the cycle. It lead to delay in period ny the 8-10 days.

2. Pregnancy:
No any contraception is 100% effective in preventing the pregnancy.
There is 5-10% of chance of the pregnancy.

I advise you to wait for period to come
If period will delay by more than 12 days then go for pregnancy test and blood HCG to confirm the pregnancy.
If you will be pregnant then still you can terminate the pregnancy by abortion pill under the advice of the gynecologist.

Avoid stress, take healthy diet and do regular exercise.
Hope this may help you
