"so i took this after a panic attack over pre ejaculate and i was in tears purchasing this.  being 16 i felt horrible and terrified.  i took this pill between 50-70 hours after. i am irregular and i took this after ovulation.  the odds seemed out of my favor.  i&#039;ve never had hormones before, this makes a difference.  i am so happy to be giving this a positive review.  my cramps, digestion, nausea, headaches, fatigue, mood swings, and other pregnancy symptoms made me terrified and ruined a good week for me.  however, i got my period 2 days late. it was so heavy and lasted forever.  but i would choose this option over pregnancy any day.  do not worry!!!!"
