"the reasons am did a review on this is because of the comfort i got from reading other reviews in my moment of panic, in hopes that mine will comfort another. took ella after a few hours after unprotected sex (bad idea) and i was a few weeks from my next period. my cycle was fairly consistent and you could only imagine the sheer panic of missing my period for 5 days. relief only came the next morning when my period resume.i was panicked because this was the longest i had gone without my period and i had no symptoms associated with taking ella so i assumed it didn&#039;t work.all i will advice is be patient, not only does ella work, but there were very few symptoms. very effective, definitely recommend it."
