Postinor 2 prevents pregnancy primarily by preventing ovulation.
Even though you took the pill eight hours later, ovulation already happened. You can hope it might have prevented pregnancy by causing changes in your cervical mucus making it harder for sperm to reach the released egg.
I would not advise you to have unprotected sex until you have vaginal bleeding, either breakthrough bleeding from taking the pill or getting your period.
If you must be sexually active before this happens, please have your partner use a condom.
If you do not have any vaginal bleeding within three weeks of taking the pill, you must test for pregnancy.
