"i&#039;m writing this because like you i was worried out of my mind after unprotected sex. i took ella 2 hours after and i was a little nauseous for the next day, i also experienced cramping for a day. after i took it i felt fine and had no bleeding. about 2 weeks after i took it i got my period (yay!) but it was one week late. so don&#039;t stress too much because it will come!"
