Birth control means preventing pregnancy (contraception). You can get pregnant even if you use birth control, but properly using birth control significantly lowers the risk of getting pregnant.
Hormones are chemical messengers one part of your body sends to another part of your body. These messengers control important body functions. Sex hormones, such as estrogen and progestin, help control a woman's menstrual periods and fertility. Doctors can use these hormones (or artificial versions of them) to prevent pregnancy.
What are hormonal methods of birth control?
Hormonal birth control works in two ways:
It keeps your ovaries from releasing eggs
It thickens the mucus in your cervix so sperm can't get through
If eggs aren't released or sperm can't get to them, you can't get pregnant.
Hormonal birth control methods include:
Birth control pills
Skin patch
Vaginal ring
Implant
Shot
How well does hormonal birth control work?
Hormonal birth control is one of the most effective methods of birth control if you use it correctly.
Your chance of getting pregnant goes up if you don't take your pills correctly, especially if you miss pills the first week after your period.
Who can use hormonal birth control?
Most women can use hormonal birth control.
You shouldn't take oral birth control (pills) that contains estrogen and progestin if you:

What are the different types of hormonal birth control?
Talk to your doctor about which hormonal birth control is right for you.
Birth control pills
Birth control pills contain both progestin and estrogen or only progestin to prevent you from getting pregnant. Progestin-only pills don’t work quite as well. Doctors usually give them only if you can’t have estrogen.
You must take a pill every day. If you skip a pill, you may get pregnant. The more pills you skip, the greater the chance of pregnancy. When you stop taking the pills, you may be able to get pregnant right away or it may take a few months.
Side effects of birth control pills may include:
Bleeding at unexpected times, particularly in the first few months of use
Feeling sick to your stomach, bloating, and throwing up
Sore breasts
Blood clots in your legs or lungs
Headaches
Depression
Dark patches on your skin (melasma)
Slightly higher chance of getting cervical cancer
Weight gain
Skin Patch
A birth control skin patch is a thin, sticky patch that slowly releases estrogen and progestin to prevent you from getting pregnant. Typically you wear a patch for 7 days and then put on a fresh one for another 7 days. After you have used 3 patches, you wait a week before starting again.
You may have to use a backup method of birth control (such as a condom Condoms A contraceptive is something used for preventing pregnancy (birth control). You can get pregnant even if you use birth control, but properly using birth control significantly lowers the risk... read more
) during the first week you use the patchYou may find it easier to remember to use a patch once a week than to take a birth control pill every day
Side effects of the patch are similar to the pill
The patch may not work as well if you're overweight
You may have pain or itching on your skin under or around the patch
Vaginal ring
A vaginal ring contraceptive is a small plastic ring that is placed in your vagina. The ring releases estrogen and progestin to prevent you from getting pregnant. Typically you leave the ring inside you for 3 weeks and then take it out for 1 week. During that week you may have a period. After the week has passed, you put in a fresh ring. Some doctors have you leave the ring in for 5 weeks and then replace it with a fresh one.

Birth control implant
A birth control implant is a match-sized rod placed under your skin that releases progestin to prevent you from getting pregnant.
An implant works for 3 years
As soon as the implant is removed, you can get pregnant
Your doctor will put the implant under your skin with a needle-like tool and remove it through a small cut in your skin
Side effects of implants may include:
Not getting your period
Bleeding at unexpected times
Headaches
Weight gain
Birth control shot
A birth control shot is a shot of long-acting progestin given every 3 months to prevent you from getting pregnant.
It may take up to 18 months after you stop the shots before you can get pregnant
Side effects of the shot may include:
Bleeding at unexpected times, especially at first
Not getting your period
Weight gain
Headaches
Less bone density (how healthy and strong your bones are)—though bone density usually returns to normal when you stop getting the shot
