I smoked an hour after i took postinor1. is it okay? im nervous. my second time to take postinor after a year.

No: No, it's not ok to smoke. The nicotine is extremely addictive, but aside from that, smoking is a habit to quit, especially for women of childbearing age. However, the postinor1 should work if not taken too late. If a regular period doesn't come in a few weeks when expected, one can do a urine pregnancy test. Of course, no smoking until then. Nor after then.
