If you are raped and worried about getting pregnant, there are steps you can take to protect yourself. Go get help immediately and get yourself to a hospital or health care provider.
All hospitals must offer you emergency contraception (EC) to prevent pregnancy.
It can be taken for up to 5 days after sex, but it works best if you take it as soon as possible. You should take it right away, even if you were using birth control. For more information on EC, see this website from Planned Parenthood.
