If you take an emergency contraception pill with levonorgestrel (like Plan B One Step, Take Action, My Way, and others) and you weigh more than 165 pounds, it won't work as well. ella is another emergency contraception pill that may work better for you. If you weigh 195 pounds or more, ella won't work as well.
No matter how much you weigh, getting certain IUDs as emergency contraception works within 120 hours (5 days) after having unprotected sex. This is the most effective type of emergency contraception. An IUD has to be put in by a doctor, nurse, or other health care provider. You can contact your gynecologist, a family planning clinic, or your local Planned Parenthood health center to find out more about getting an IUD.
