Birth Control Pill


What Is It?



The birth control pill (also called "the Pill") is a daily pill that
contains hormones to change the way the body works and prevent
pregnancy. Hormones are chemical substances that control the functioning
of the body's organs. In this case, the hormones in the Pill control
the ovaries and the uterus.

How Does It Work?



Most birth control pills are "combination pills" containing a
combination of the hormones estrogen and progesterone to prevent
ovulation (the release of an egg during the monthly cycle). A woman
cannot get pregnant if she doesn't ovulate because there is no egg to be
fertilized. The Pill also works by thickening the mucus around the
cervix, which makes it difficult for sperm to enter the uterus and reach
any eggs that may have been released. The hormones in the Pill can also
sometimes affect the lining of the uterus, making it difficult for an
egg to attach to the wall of the uterus.





Most combination pills come in either a 21-day pack or a 28-day pack.
One hormone pill is taken each day at about the same time for 21 days.
Depending on your pack, you will either stop taking birth control pills
for 7 days (as in the 21-day pack) or you will take a pill that contains
no hormones for 7 days (the 28-day pack). A woman has her period when
she stops taking the pills that contain hormones. Some women prefer the
28-day pack because it helps them stay in the habit of taking a pill
every day.

There is also a type of combination pill that decreases the frequency
of a woman's period by supplying a hormone pill for 12 weeks and then
inactive pills for 7 days. This decreases the number of periods to one
every 3 months instead of one every month.

Another kind of pill that may change the number of monthly periods is
the low-dose progesterone pill, sometimes called the mini-pill. This
type of birth control pill differs from the other pills in that it only
contains one type of hormone — progesterone — rather than a combination
of estrogen and progesterone. It works by changing the cervical mucus
and the lining of the uterus, and sometimes by affecting ovulation as
well. The mini-pill may be slightly less effective at preventing
pregnancy than combination pills.

The mini-pill is taken every day without a break. A girl who is
taking the mini-pill may have no period at all or she may have irregular
periods. For the minipill to work, it must be taken at the same time
every day, without missing any doses.

Any type of birth control pill works best when it is taken every
single day at the same time of day, regardless of whether a girl is
going to have sex. This is especially important with progesterone-only pills.

For the first 7 days of taking the Pill, a girl should use an
additional form of contraception, such as condoms, to prevent pregnancy.
After 7 days, the Pill should work alone to prevent pregnancy. But
continuing to use CONDOMS will protect against Sexual transmitted disease


If pills are skipped or forgotten, a girl is not protected against
pregnancy and she will need a backup form of birth control, such as
condoms. Or she will need to stop having sex for a while. Do not take a friend's or relative's pills.

How Well Does It Work?



Over the course of 1 year, about 8 out of 100 typical couples who
rely on the Pill to prevent pregnancy will have an accidental pregnancy.
Of course, this is an average figure and the chance of getting pregnant
depends on whether you take your birth control pills every day. The
Pill is an effective form of birth control, but even missing 1 day
increases the chance of getting pregnant.

In general,how well
each type of birth control method works depends on a lot of things.
These include whether a person has any health conditions or is taking
any medications or herbal supplements that might interfere with its use.
For example, antibiotics or an herb like St. John's wort can interfere
with the effectiveness of the Pill.

How well a particular method of birth control works also depends on
whether the method chosen is convenient — and whether the person
remembers to use it correctly all the time.

Protection Against STDs



The birth control pill does not protect against STDs. Couples having sex must always use condoms along with the Pill to protect against STDs.

Abstinence (the decision to not have sex) is the only method that always prevents pregnancy and STDs.

Possible Side Effects



The birth control pill is a safe and effective method of birth
control. Most young women who take the Pill have none to very few side
effects. The side effects that some women have while on the Pill
include:

• irregular menstrual bleeding
  
• nausea, headaches, dizziness, and breast tenderness
  
• mood changes
  
• blood clots (rare in women under 35 who do not smoke)
  

Some of these side effects improve over the first 3 months on the
Pill. When a girl has side effects, a doctor will sometimes prescribe a
different brand of the Pill.

The Pill also has some side effects that most girls are happy about.
It usually makes periods lighter, reduces cramps, and is often
prescribed for women who have menstrual problems Taking the Pill often improves acne, and some doctors prescribe it for
this purpose. Birth control pills have also been found to protect
against some forms of breast disease, anemia, ovarian cysts, and ovarian
and endometrial cancers.Who Uses It?



Young women who can remember to take a pill each day and who want excellent protection from pregnancy use birth control pills.



Not all women can — or should — use the Pill. In some cases, medical
or other conditions make the use of the Pill less effective or more
risky. For example, it is not recommended for women who have had blood
clots, certain types of cancers, or certain types of migraine headaches.
It's recommended that girls who have had unexplained vaginal bleeding
(bleeding that is not during their periods) or who suspect they may be
pregnant should talk to their doctor.

Girls who are interested in learning more about different types of
birth control, including the Pill, should talk to their doctors or other
health professionals.

How Do You Get It?



A doctor or a nurse practitioner must prescribe the Pill. He or she
will ask about a girl's health and family medical history, and do a
complete physical exam, which may include a pelvic exam. If the doctor
or nurse prescribes birth control pills, he or she will explain when to
begin taking the Pill and what to do if pills are missed.

The doctor or nurse will usually ask the girl to come back in a few
months to have her blood pressure checked and to see if she is having
any problems.

After that, girls who are having sex should get routine exams every 6 months to a year, or as recommended by the doctor.

How Much Does It Cost?



The Pill usually costs between $15 and $50 a month, depending on the
type. Many health and family planning clinics (such as Planned
Parenthood) sell birth control pills for less. In addition, birth
control pills and doctor visits are covered by many health insurance
plans.
