Levonorgestrel
"I took Aftera just 2 hours after unprotected sex. Now, 25 days later, my period is late, I'm nauseous with two positive pregnancy tests .WOW. NOT WORTH IT. PLEASE use PLAN B instead of this. I had no symptoms after taking this (as compared to the cramping and what not from PlanB.)  Aftera probably packs their packages with sugar pills. What a terrible situation to be in."
