How do the birth control pills work?

The birth control pills are a day-to-day pill which contains hormones able to change the mode of operation of the body and prevent a pregnancy.

How do the birth control pills work

Hormones are chemical substances that control the functioning of the organs. In this case, the hormones control the ovaries and uterus.

How do they work?
Most birth control pills contain a combination of progesterone and oestrogen to prevent ovulation. A woman cannot get pregnant if she has no ovulation since there is no egg to be fertilized. The pill may also serve to thin the mucus in the cervix which impedes the penetration of sperm up into the uterus. The hormones in birth control pills sometimes affect the uterus tissue, which does not allow for the egg to attach to the wall.

Types of birth control pills
Many of these pills can be found in blisters of 21 or 28 pills. You should take one pill every day, at the same time, for 21 consecutive days. Depending on the type of the pill you take, you will stop taking them for 7 days (if 21 pills), or you may take birth control pills that contain no hormones – those 7 provided in addition (if you are using 28 pills). A woman enters the period of menstruation when she stops taking birth control pills that contain hormones. Some prefer the 28 set because they keep the habit of taking the pill every day.

Another pill can change the number of menstrual cycles and it contains a low dose of progesterone being also called a mini-pill. Although it acts by changing the mucus of the cervix, it is not as secure as compared to other types of birth control pills. The mini-pill is administered every day without break. A woman who takes this pill may not have a menstrual period at all or may have an irregular cycle. In order for it to function at optimal capacity, the pill must be taken every day at the same hour, with no exceptions.

When do they start to function?
In fact, any kind of birth control pill works better when it is taken regularly, at fixed hours. In the first 10 days of taking the pill, you need to use an additional method of contraception, such as a condom, to prevent an unwanted pregnancy. 7 days later, the pill provides sufficient protection.

You have to remember: the birth control pills do not protect you from sexually transmitted diseases (STD). You never should take birth control pills that have been prescribed for another person. These pills are given after a proper medical check-up because your body needs a certain intake of hormones provided by a specific type of pills. Also, your doctor may recommend birth control pills to certain women whose hormone level must be balanced.
