Levonorgestrel
"It's annoying to pull money out of your pocket to buy little things like this because of a little accident or a little overthinking/hesitation. If you're starting to hesitate whether or not the guy has finished inside of you and you just have a gut feeling that he did. Take the pill. Mistakes happen so stop calling yourself stupid. 



I took Aftera about 10 hours after intercourse. The condom ended up breaking and I just wanted to be safe. Aftera is usually $10 cheaper than Plan B. Anyway, I took it and the only side effects I got were cramping and a slight headache but they were both manageable and nothing too bad.  Both subsided within 2 and a half hours. Got my period on the day it was supposed to."
