Birth Control (Contraception)

Birth control, or contraception, can prevent or help you plan the timing of pregnancy. Because there are many birth control options, it might take some time to find the best one for you.

Before making your decision, consider researching each method, talk about it with your partner, and make a list of questions for your doctor. It's also important to consider the risks for each method – which may include weight gain, changes in mood, allergic reactions and irregular periods.

No matter which method you choose, it's important to follow all directions carefully to avoid pregnancy. And if you're concerned about protection against sexually transmitted diseases (STDs), condoms are the only contraceptive that offers some protection against most STDs.

How to talk to your doctor

Your doctor can help choose the right method of birth control for you. Some things to consider during the discussion:

  • Your overall health
  • How often you have sex
  • How many sexual partners you have
  • If you want to have children in the future
  • If you will need a prescription or if you can buy the method over the counter
  • The details of the method, including how it works, its risks and its effectiveness in preventing pregnancy

Certain behaviors and health conditions may affect the reliability of some birth control methods. So tell your doctor if you:

  • Smoke
  • Have liver disease
  • Have blood clots or have family members who have had blood clots
  • Are taking any other medicines
  • Are taking any herbal products, like St. John's Wort
