Levonorgestrel
"There's a lot of talk that this pill is not as effective for larger ladies, so I want to make it clear that I am approximately 280 lbs. I had unprotected sex approximately 3 or 4 days after my menstrual cycle ended, so I was considered very fertile at the time, and I am a highly fertile person in general, my partner ejaculated inside of me. I went to the store and purchased a Plan B pill and took the pill approximately 35 - 40 minutes after sex. A few days later I started having pregnancy like symptoms, lots of gas, breast tenderness, mild nausea.. I was freaked out!! I got my period 2 weeks later (a week early for me).. THIS PILL WORKS! EVEN FOR PLUS SIZE LADIES!! Take it ASAP after sex, I'm going to buy one to have on hand for the future!"
