Birth control means preventing pregnancy (contraception).
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?
How well does hormonal birth control work?
Hormonal birth control is one of the best methods if you use it correctly. If you do, your chance of getting pregnant the first year you use it is only about 3 in 1000.
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:
-
Are 35 or older and have migraine headaches
-
Have migraine headaches with an aura (symptoms that happen before a migraine headache, such as seeing lights or having unusual feelings in your skin)
-
Have or have had blood clots in your legs or lungs
-
Have high blood pressure
-
Have had diabetes for more than 20 years
-
Have high fat levels in your blood called triglycerides
-
Have a heart disease
-
Are 35 or older and smoke more than 15 cigarettes a day
-
Have had an organ transplant that is causing problems
-
Have a liver disease
-
Have had jaundice (yellow skin and eyes) when using birth control before
-
Have gallbladder problems
-

If you’ve had weight-loss surgery, you shouldn’t use the pill, but you can use a skin patch or vaginal ring.
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:
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) during the first week you use the patch
-
You 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.

You may have to use a backup method of birth control (such as a condom) during the first week you use the ring
-
You may find it easier to remember to use a ring once every 3 to 5 weeks week than to take a birth control pill every day or put on a patch every week
-
On the other hand, because you can't see or feel the ring, it's easy to forget to remove and replace it
