What is the birth control pill?
A birth control pill is a type of contraception method. It is used by women, and taken orally once a day. Most birth control pills contain two hormones - estrogen and progestogen, which is why these are also referred to as combined hormonal contraceptive (CHC) pills, or combined oral contraceptive (COC) pills, or just the pill.
Birth control pills have been used by women worldwide for almost 60 years. There are various brands and formulations available, however majority of them contains estrogen and progestin. The natural forms of these two hormones help regulate the menstrual cycle and play an important role in reproductive health.
In addition to having a contraceptive effect, birth control pills have several non-contraceptive benefits as well. If you are considering this form of contraception, it is important that you make informed decisions, and ensure that you are aware of its effectiveness as well as potential risks and benefits.

How does the birth control pill work?
The pill works by preventing the ovaries from releasing an egg each month (called ovulation). It also thickens the mucus in the neck of the womb (cervix), so it is harder for sperm to penetrate the womb and reach an egg. In addition, it thins the lining of the womb, so there is less chance of a fertilized egg implanting into the womb.
How effective is the birth control pill in preventing pregnancy?
The birth control pill is a very effective method of contraception, however it is also highly user dependent, and its effectiveness is based on its typical or perfect use.
Perfect use means that you use the pill consistently, without missing any pills, and once a pack/cycle is finished start the new pack on time. Typical use means that you don't always take the pill consistently or correctly.
If used perfectly, the pill is more than 99% effective, which means the risk of contraceptive failure with the pill is low (less than 1%). With typical use, however, when the pill is not taken consistently or restarted on time, it is estimated to be 91% effective. Other factors can also affect the effectiveness of the pill, such as interactions with other medications that may be taken at the same time and special circumstances (for example diarrhea and vomiting).
When seeking birth control with Dear Doc, we ask our users if they are currently taking any medications or supplements. Once you start using birth control, it may be a good idea to check with our doctor before taking any new medicines, including herbal remedies, and let our the doctor know if you are not feeling well due to diarrhea or vomiting.

It can have side effects in some women, such as break-through bleeding, during the initial few weeks and months of its use.
