emergency contraception
"I've taken Plan B more times than I am willing to admit, but I have had 100% effectiveness with this pill. While I highly, highly recommend regular birth control, sometimes the use of this pill is necessary. I used it three weeks ago after having sex. The condom broke at the last second and he came inside of me. I was so nervous because my ovulation window had fallen right around the same time (like the last few days of the window) and I was seriously praying for the pill to work. I had all of the side effects from the morning-after pill all week long. I'm happy to say, though, the pill WORKED and I have my period now. Do NOT freak out, I can tell you that using this pill, although it wreaks havoc on your body, is effective!"
