The use of the morning-after contraception pill has increase significantly among American women.
The pill is considered emergency contraception to prevent unwanted pregnancy.
A new report from Centers for Disease Control and Prevention shows the number of women who said they had used the pill had jumped to 11 percent in 2010 from 4.2 percent in 2002.
That translates to 5.8 million women who were between the ages of15 and 44.
The government report found the pill was particularly popular among women ages 20 to 24. Fourteen percent were teens ages 15 to 19.
Nineteen percent of the women who used the pill weren't married, and 14 percent lived with a partner.
The most common reasons for using the pill were a woman's fear that the contraceptive she was using might not work, or because she had unprotected sex.
