"relax!!!!! plan b works. i too was worried for my life that it wouldn&#039;t but fortunately it did. long story short i had intercourse with my gf. the condom broke and we didn&#039;t use birth control. plus i made the mistake of finishing inside. i thought i was done for at the time. until i realized that she was on the 8th day of her ovulation cycle when we had intercourse and that on the 9th day i gave her that single plan b pill. about a month later her period finally came and it all was behind us. best $50 spent."
