Levonorgestrel
"I'm 17 and my boyfriends condom broke during sex like most. Being my age a child is not something we need right now. I was very panicked and immediately got the pill. After reading many reviews on it I took it about 4 hours after the mishap. The only side effect I had was tender breasts. I got my period on my exact due date! This pill works! I promise you. Don't worry it will be okay !"
