(NBC NEWS) The condom is still king when it comes to matters of love, but more U.S. women are using newer methods of preventing unwanted pregnancy such as emergency contraception and implants, new federal data shows.

About 11 percent of all women have used emergency birth control such as the “Plan B” pill, and 59 percent of them had only used it a single time, the National Center for Health Statistics reported on Thursday.

About half of women reported using the morning-after pill because they feared a method they were already using, such as a condom, had failed, and 49 percent said they used it because they had unprotected sex, Kimberly Daniels and colleagues at NCHS, part of the Centers for Disease Control and Prevention, reported.
