You can use emergency contraception if a condom breaks, you've forgotten a pill, you are taking other medications that may affect contraception medications, or you have had unprotected sex. Emergency contraception does not protect against sexually transmitted diseases.

There are two kinds of emergency contraception:

• Hormonal emergency contraception.
  Even though it is called the "morning-after pill," hormonal emergency contraception is effective when taken up to 5 days after unprotected sex, although it is most effective when it is used within 72 hours.
• Copper T intrauterine device.
  The copper IUD is inserted within 7 days after unprotected sex.

The Emergency Contraception Web site at http://ec.princeton.edu/ can help you find an emergency contraception provider close to you.

You can buy Plan B in most drugstores.

• If you are 18 or older, you can get Plan B from a pharmacist, without a prescription. Bring proof of your age.
• If you are younger than 18, you can get Plan B with a prescription.

Some pharmacists refuse to fill emergency contraception prescriptions based on their personal beliefs. If this happens to you, ask for the location of a pharmacist who will fill the prescription, use the Web address above, or call the Planned Parenthood clinic closest to you.

Different birth control methods have different side effects and possible complications. It is important to understand the risks of the birth control method you use. Talk to your health professional if you have concerns about side effects.

Call your health professional if you have symptoms of pregnancy, such as having missed one or more periods or having your period but with a lot less bleeding than usual. Take a home pregnancy test. If the test is negative but you still suspect that you are pregnant, schedule an appointment with your health professional.

If you are an adult, the law protects the privacy of your health information. Your gynecological exam and test results are your private information. Your health professional will not share your private information with anyone but you unless you give him or her permission to do so.

If you are a teen, your privacy depends on the laws in your state. Most state laws protect a teen's privacy and freedom to see a health professional for birth control services. Some states, however, require most teens to have a parent's consent for prescription birth control. For information about your state's laws, see Minors' Access to Contraceptive Services at www.guttmacher.org/statecenter/contraception.html.

Call your health professional immediately
if you have any of the following symptoms:

Hormonal methods

• Sudden or severe abdominal pain
• Sudden or severe chest pain
• Sudden shortness of breath or difficulty breathing
• A severe headache
• Sudden eye problems or changes in your vision
• Severe leg pain (anywhere, most likely in your calf)

Intrauterine device (IUD)

• Symptoms of pregnancy, such as missing a period or tender breasts
• Fever of 100° F (37.8° C) or higher
• Pain in the lower abdomen
• Bad-smelling, heavy discharge from the vagina
• Vomiting not caused by stomach flu

Pregnancy after sterilization is rare. However, when it does happen, the risk of tubal (ectopic) pregnancy is higher than normal. If you have had a tubal ligation or tubal implants and now have possible pregnancy symptoms, have a pregnancy test right away. An ectopic pregnancy can become life-threatening.

If you have an IUD or have had a sterilization procedure, your health professional will give you instructions to follow.
