"i took postinor 2 within 12 hours of the unprotected sex then two days after had i brown spotting for 3 days. i read online that brown spotting is a sign of an early pregnancy. i was worried sick  i took a pregnancy test and the result was negative. i ate parsley then the next day my period came but it came 5 days early. it truly works !! don&#039;t worry. don&#039;t wait take it within the recommended time"
