Levonorgestrel
"Long story short,Condom broke. Took the pill like 7 hours after it did, (7a.m).  I was soooo scared! I wasn't ready for a kid. We went to Walmart and bought Plan B. And now it's just been exactly one week since I've took it, and I've started my period. I'm so relived,and So happy that it worked. This is not a spam either. I saw that a lot of people were saying it didn't work, and it kinda worried me. Because I didn't want to spend like 50$ if it didn't work. But it truly did. Plan B  really works."
