emergency contraception
"I took Plan-B after having unprotected sex right after my period ended. He got it for me to ease both our minds. Within a week of taking the pill, I had some side effects, like headaches and dizziness. After 7 days I received an early period. It was painful, and I had bad cramps. I was worried at first because I had just had my period, but Plan-B and you guys reviews all said bleeding and irregular periods were a common system. It really worked! So no worries if this happens to you! I will suggest no intercourse until you get your next period just in case, and a pregnancy test to ease your mind."
