emergency contraception
"We had a failure with the condom. After my girlfriend was able to take the pill 9 hours later. She had a couple days of intense cramping but it came and went. 2 weeks later she got her period on time. I would highly recommend to take the pill within the first 12 hours. If you do You should be fine. The sooner you take it the better. So don't stress about it to much, you will drive yourself crazy when there's a high chance you won't get pregnant. My situation was pretty bad so I'm sure if it worked for me, it will work for you."
