Postinor2 is a very effective medicine and you have taken it well in time so it is highly unlikely that you could be pregnant but you should have avoided the unprotected intercourse
The emergency contraception
drugs cause negative impact on your health and cause hormonal
I think you will have periods with some delay.
If even then in doubt, you can do urine pregnancy

If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
