Birth control pills are a type of hormonal contraception that is taken orally by women. They contain a combination of estrogen and progestin hormones, which work to prevent pregnancy in a few ways:
Ovulation inhibition: The hormones in the pill prevent the ovaries from releasing an egg each month. Without an egg, there is nothing for sperm to fertilize.
Thickening of cervical mucus: The hormones in the pill thicken the mucus around the cervix, making it more difficult for sperm to travel through the vagina and reach the uterus.
Altering the lining of the uterus: The hormones in the pill can also thin the lining of the uterus, making it less likely for a fertilized egg to implant and grow.
There are two main types of birth control pills: combination pills and progestin-only pills. Combination pills contain both estrogen and progestin, while progestin-only pills contain only progestin.
Combination pills are the most common type of birth control pill. They are very effective at preventing pregnancy when taken correctly, with a failure rate of less than 1%. However, they can have some side effects, such as nausea, vomiting, weight gain, and mood changes.
Progestin-only pills are less effective than combination pills at preventing pregnancy, with a failure rate of about 5%. However, they have fewer side effects than combination pills.
Both combination pills and progestin-only pills can be used to prevent pregnancy. The best type of pill for you will depend on your individual needs and preferences.
Here are some additional information about birth control pills:
Birth control pills should be taken at the same time each day. If you miss a pill, take it as soon as you remember. If you miss more than one pill, you may need to use a backup method of birth control, such as condoms.
Birth control pills can be taken for up to 20 years. However, it is important to talk to your doctor about whether or not birth control pills are right for you.
Birth control pills can help to regulate your menstrual cycle, make your periods lighter and less painful, and reduce your risk of ovarian and endometrial cancer.
Birth control pills can also increase your risk of blood clots, stroke, and heart attack. If you have any of these risk factors, talk to your doctor about whether or not birth control pills are right for you.
If you are considering using birth control pills, talk to your doctor about the risks and benefits. They can help you decide if birth control pills are the right choice for you.
