emergency contraception
"I'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't stress too much because it WILL come!"
