"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&#039;t stress about it to much, you will drive yourself crazy when there&#039;s a high chance you won&#039;t get pregnant. my situation was pretty bad so i&#039;m sure if it worked for me, it will work for you."
