"i took morning after pill 12 hours after unprotected sex. i felt so tired and sleepy and nauseous, my stomach hurts too. my period is due 21 of march 2017. my body had these weird chilling sensation so i won&#039;t take the morning after pill again. i rate like this because i don&#039;t know if it will work or not. i will update later as the days progress and hope i get my period"
