In brief: Low but real

Postinor-2 is an emergency contraceptive that involves taking 2 pills.
It is 95% effective if the first pill is taken within 24 hours after unprotected intercourse but the second pill should be taken exactly 12 hours later. Since you waited 16 hours it may be somewhat less effective. You may want to do a pregnancy test in 10 days to 2 weeks to know for sure. Hope this helps.
