It looks like more and more women are resorting to Plan B.
About 1 in 9 sexually-active young women have used the "morning-after" pill at least once, according to a report from the Centers for Disease Control and Prevention released Thursday.
That's up four percent from 2002, just few years after the pills went on the market as prescription-only.
The increased usage is probably because emergency contraception is easier to get. A prescription is still required for those younger than 17, so it is still sold from behind pharmacy counters.
The morning-after pill's use was most common among women ages 20 to 24. Half the said they took the pills it because they had unprotected sex, while others cited a broken condom or concerns with the effectiveness of their birth control method.
This is the first government report to focus on emergency contraception since its approval 15 years ago.
