Levonorgestrel
"To all stressed out girls reading this: I was you until today. I had sex with my bf two weeks ago but he pulled out. I freaked out a day after, after doing some web research. We got levonorgestrel (we don't have Plan B here) 30 hours later. During these excruciating two weeks, I convinced myself I was pregnant because I did the one thing we all know we shouldn't do but we do anyways: web research. I invented pregnancy symptoms or really noticed those of PMS I had never ever paid attention to before, and it was horrible. I cried every night, I prayed every second. My period was late, and though I knew it might've been a side effect, I was beginning to lose hope (the step after you panic). BUT IT WORKED. I got what should be my period today!!"
