emergency contraception
"THIS WORKS. I had no doubt in my mind about that! So basically my boyfriend and I are always using protection but about 5 days ago that condom slipped off. About 12 hours later we bought Plan B and I took it. I was due for my period like 2 days after but it never came. After what felt like the longest 5 days ever, I finally got it today! So don't worry, periods are often delayed by this. Anyways, this saved our lives. Whew!"
