Almost all women in the United States use birth control at some point. After all, it’s one of the easiest ways to take control of your future plans and live life the way you want.

Perhaps in part because it’s so popular, there are many birth control options to choose from. Some you may have heard about or tried, while other options might be new to you. Finding the contraception that works best for your personal lifestyle and family planning can be very rewarding because it lets you direct your life the way you want. But you can spend a lot of time and energy trying out different types of birth control, and it’s easy to get frustrated before you find the right one. With so many possibilities, where do you start? What should you keep in mind?

Below we’ve collected the most important details so you can easily compare different birth control options and start a conversation with your doctor. Let’s get started.

Types of birth control

Generally, there are five categories of birth control methods. Each method works in a different way, like preventing sperm from getting to an egg or discouraging your body from releasing eggs. But every contraceptive technique has the same primary goal of helping you avoid unwanted pregnancy.

One thing to note before we dive in: Birth control and sexually transmitted infection (STI) prevention aren’t the same thing. Only condoms protect against STIs when used correctly. If STI prevention matters to you, you’ll want to use condoms in combination with another method.

1. Short-acting hormonal contraception

Hormonal birth control involves adjusting your body’s natural estrogen and/or progestin levels to make pregnancy much less likely. Common methods include birth control pills you take every day, a patch you replace every week, a vaginal ring you change every month or a shot your doctor gives you every three months. All of these methods require a prescription. For most women, they’re about 91% to 95% effective at preventing pregnancy.

Hormonal birth control side effects can vary, especially when you’re just starting out. But one beneficial side effect that many women notice is a decrease in period pain, frequency or flow. If your menstrual cycle gives you trouble, a hormonal birth control option is definitely worth exploring.

2. Long-term contraception

Long-term contraception can be a good choice if you want effective, lasting birth control without much maintenance. Choices include an implant inserted into your arm or an intrauterine device (IUD) inserted into your uterus. These methods are 99% effective at preventing pregnancy. They’ll work for 3–10 years, depending on the particular method you choose. The implant (Nexplanon) and hormonal IUDs (such as Skyla, Mirena, Kyleena) work by adjusting your body’s progestin levels over time. Copper IUDs (ParaGard) do not use hormones. Instead, the copper stops sperm from fertilizing your eggs.

Implants or IUDs can be great options because they don’t require any extra work on your part: Once your doctor puts in the device, you’re covered. But if your plans change and you’d like to have kids, it’s easy to get your implant or IUD removed. You may experience a little discomfort when your device is put in place, and some people can experience a few temporary or (less commonly) ongoing side effects such as weight gain, headaches and soreness. But many women find the benefits of low-maintenance, long-term birth control to be well worth it.

3. One-time barrier contraception

Condoms, sponges, diaphragms, cervical caps and spermicide are all barrier birth control methods. They each work differently, but they all create a sperm “barrier” during sex to physically prevent sperm from reaching an egg. Barrier contraception methods don’t require a prescription and are available at many stores or online. Additionally, condoms help protect against STIs, the only birth control method to do so.

You only use barrier contraception when you’re actually having sex. You need to use it every time you have sex and also need to use barrier contraception correctly for it to be most effective. Because of this, barrier contraceptive techniques don’t usually work as well. They prevent pregnancy between 71% and 88% of the time, depending on the method. But you can also combine methods for greater effectiveness. For example, it’s recommended that you also use spermicide if you’re using a diaphragm or cervical cap. Talk to your doctor for specifics.

4. Permanent contraception

Tubal ligation (for women) or vasectomy (for men) are relatively simple surgical procedures intended to make pregnancy impossible. They’re almost 100% effective at preventing pregnancy. If you’re very sure you don’t want to have children in the future, they’re a great option to consider.

Recovery time from these procedures usually takes only a few days. Your (and your partner’s) sexual function won’t be impacted, and if you choose tubal ligation, you’ll still get your period. Essentially, nothing will change in your day-to-day life, except that you won’t be able to get pregnant. This makes permanent contraception one of the most convenient birth control options, but only if you’re confident you don’t want kids going forward. Reversing a tubal ligation or vasectomy is possible, but there isn’t any guarantee your fertility will return.

5. Emergency contraception

If you have sex without using birth control – or your birth control fails – emergency contraception can help prevent pregnancy. If you need emergency birth control, there are two types of pills available as well as a copper IUD. No matter which method you prefer, you’ll want to use emergency contraception as soon as possible for it to be most effective.

One type of pill, often called “Plan B,” is available from most pharmacies without a prescription; it can prevent pregnancy up to three days after sex. The more effective pill, often called “Ella,” does need a prescription but can prevent pregnancy up to five days after sex. Copper IUDs also require you to see a doctor, but they’re almost 100% effective when inserted within five days of intercourse.

Emergency contraception isn’t meant to be your primary birth control method – only a backup in case something doesn’t go as planned. You’ll have more control if you regularly use other methods first.

So what’s the best birth control?

It all depends on you. For starters, you’ll want to consider what your goals are, what your lifestyle is like, how often you have sex, whether you have insurance, what you and your partner are comfortable with and what you’re planning for the future.

Because every woman is different, the contraception that works best for your friends or family members may or may not be convenient or most effective for you. But regardless of the birth control method you end up choosing, use it as directed for the lowest chance of pregnancy.

Of course, you’ll want to talk to an OB-GYN to get personalized birth control advice. Your doctor can give you more details about each option, and they’ll help you make a choice (or choices) you’ll feel great about.

Taking time to make sure you’ve selected the best birth control option for you can give you more power over your choices. And that’s well worth it for your health, your well-being, your peace of mind and your future.
