emergency contraception
"Plan B one step is a LIFESAVER. My boyfriend and I had un protective sex. So within 4 hours after the incident, I took the pill. I was paranoid as hell, not sure whether this pill would work or not ( my first time taking it and I am also young). I experienced mild cramping , head aches and nausea for five days. But my period came on time ! The key is to stay calm and let the pill do its job."
