Overview

Birth control is any method used to prevent pregnancy. Another word for birth control is contraception.

If you have vaginal sex without birth control, there is a chance that you could get pregnant. This is true even if you have not started having periods yet or you are getting close to menopause.

The only sure way to prevent pregnancy is to not have vaginal sex. But finding a method of birth control that works for you can help you avoid an unplanned pregnancy.

Be sure to tell your doctor about any health problems you have or medicines you take. Your doctor can help you choose a birth control method that will work for you.

Types of Birth Control

There are many kinds of birth control. Each has pros and cons. Find what works for you.

Birth control following pregnancy

Talk to your doctor about the options for birth control after your delivery. They include implants and intrauterine devices (IUDs), hormonal methods, and barrier methods. Many types of birth control are safe to use if you're going to breastfeed. But some work better than others.

Choosing a Birth Control Method

Before you choose birth control, you might think about:

How well it works.

How easy it is to use.

How much it costs.

Whether it protects you from sexually transmitted infections (STIs).

Whether it uses hormones.

If you want to get pregnant later.

How easy it is to get.

Privacy.

How it fits into your life.

If you have health problems.

Time and effort to use

Birth control must be used correctly in order to prevent pregnancy. When you decide which birth control method to use, be honest about how much effort you are willing to put into birth control. If you aren't comfortable with or might not consistently use a birth control method for any reason, that method isn't likely to be reliable for you in the long run.

Some birth control methods require more effort than others.

• Long-acting reversible contraception (LARC) (such as implants and IUDs) works to prevent pregnancy for years. After it's in place, you don't need to do anything.
  • The implant is approved by the U.S. Food and Drug Administration (FDA) to be used for up to 3 years. But studies show that extended use of the implant safely prevents pregnancy for up to 5 years. Talk to your doctor about what might be right for you.
  • The hormonal IUD prevents pregnancy for 3 to 8 years, depending on what brand you have. The copper IUD is approved by the FDA to be used for up to 10 years. But studies show that extended use of the copper IUD safely prevents pregnancy for up to 12 years. Talk to your doctor about what might be right for you.
• Barrier methods (including the diaphragm; cervical cap; condoms; and spermicidal foam, sponge, gel, suppository, or film) can interrupt sex. And you have to use them every time you have sex.
• Combination pills are taken each day. Progestin-only pills must be taken at the same time each day. If you miss a pill, you'll need to use a backup birth control method.
• Patches are replaced 3 times each month.
• Vaginal rings are inserted into the vagina 1 time each month.
• Fertility awareness requires that you keep track of changes your body goes through during your menstrual cycle. You must avoid vaginal sex or use a barrier method during that time.
• Sterilization is a surgical procedure. It's done if you decide that you don't want to have any (or more) biological children. It's intended to be permanent.

Health issues that might limit your choices

If you have health problems or other risk factors, some birth control methods may not be safe for you. To make sure a method is right for you, your doctor will need to know if you:

• Smoke. If you smoke more than 15 cigarettes a day and are 35 or older or have high blood pressure, a history of stroke, a history of blood clots, liver disease, or heart disease, you may not be able to use combined hormonal methods.
• Have any serious health problems, such as heart disease, high blood pressure, diabetes, or migraine headaches.
• Have had blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism), or have a close family member who had blood clots in the legs or lungs.
• Are pregnant.
• Have just delivered a baby. If you just had a baby, the estrogen-progestin methods of birth control aren't recommended in the first few weeks.
• Have breast cancer or a history of breast cancer.
• Have a sexually transmitted infection (STI).

Emergency Contraception

Emergency contraception is a way to prevent pregnancy after unprotected vaginal sex. For example, you can use it if:

• You had sex without using birth control. There is a chance that you could get pregnant even if you haven't started having periods yet or you are getting close to menopause.
• Your birth control method failed. Maybe you forgot to take your pill or get your shot. Or maybe the condom broke or came off, or your diaphragm slipped.
• You used a birth control method that isn't very reliable, or you didn't use it the right way.
• You were sexually assaulted. Even if you were using birth control, emergency contraception can help decrease your chance of getting pregnant.

There are two types of emergency contraception: pills or an intrauterine device (IUD). Using emergency contraception right away can prevent an unwanted pregnancy. And it can keep you from worrying while you wait for your next period to start.
