Levonorgestrel
"I had unprotected sex and he came inside of me exactly two weeks after my period. Which after doing a little internet research I find that's when I'm most likely ovulating. (I don't follow my ovulation so I wouldn't know exactly.) I am not on birth control. 

I took Plan B (or maybe some off brand that's supposed to be the same thing but wasn't listed) approximately 12 hours after the incident. 

I am also 20 pounds over the "weight limit" suggested for this product. 

I got my period today, right on time! I had no side effects from the pill other than a tiny amount of spotting a few days after I took it. 

These reviews really helped calm me down as I was waiting for my results, so I thought I would contribute."
