Levonorgestrel
"I'm gonna put out there that I weigh about 145 pounds and I am Hispanic. I am also 16 and am in no position to be a mother. My boyfriend and I always use condoms. But we did begin once without one and although he never came inside of me there is such thing as pre ejaculation. So we just took precautions! So I took the pill less than 2 days later! I will mention that I was suppose to receive my period the same day I took the pill so it pushed it back. The only symptoms I got was fatigue, nausea, and a little cramping here and there. After a week of having the pill in my system I got my period. Don't stress. This saved me"
