Levonorgestrel
"I just want to share my experience on this drug. I had unprotected sex with my husband, the day after my period ( August 28, 2015 ) Friday. He didn't ejaculate. but we're not ready for a baby yet. so, just to make sure I took Plan B one step the next day ( Saturday, August 29) 

At first day, I felt okay, nothing is bothering me. till I felt nauseous, dizzy and I'm having cramps ( assuming that my period would come out again). I just let it and as of the description of the box said that its normal to feel those symptoms.

after 1 week, ( Saturday, September 5th)  I started to have bleeding, I assumed it was my breakthrough bleeding. it lasted for 4-5 days ( like my normal period) 

This medication is 100% real and it works for me."
