I want to know all about contraception. 
1. Condoms
2. Birth control pills :  when a women is on birth control pills and
has unprotected sex does she get pregnant if the semen is discharged
inside her body?
3. How is no.2 related to her periods.

Hi sandynaik,

First, I'll address your 3rd question:  "How is no. 2 related to her periods."

The pill is 99.7% effective against pregnancy when used correctly. 
That means taking the pill during the days your doctor has prescribed
for you.  If you started taking the pill just before or during your
period, then you shouldn't have to worry about becoming pregnant. 
But... if you started taking the pill later then you must a condom for
7 days while you wait for the pill to start working.  You can view the
source of this information at the following site in the middle of the
page.

According to Frequently Asked Questions - Pregnancy
http://www.everybody.co.nz/sexfiles/faq_pregnancy.html

Question: I just started taking the pill about 4 days ago. I had sex
after 3 days and I let him come inside me. What is the chance I will
become pregnant?

Answer: Your chance of getting pregnant depends on when your last
period was. If you started taking the pill just before or during your
period then you should be safe. But if you have started the pill
later, then you should be following the 7-DAY RULE, which says you
must use a condom for 7 days while you wait for the pill to start
working.

You probably know this, but it is worth pointing out the protection
and contraception are different. Condoms are both. They protect one
against some STDs while also serving as a contraceptive.

It should also be noted that some women suffer adverse side-effects
from Hormonal birth control, such as the pill, that new patch, or
shots. tlspiegel is right, Planned Parenthood is a wonderful resource.
Use it!

i'm not a real dr. I just play one on the innernet. since i'm playing
dr. and not a real one, you should look at the information you were
given.

some things i would like to add:

birth control pills will make your periods more regular.

Common side effects are headaches, and generally more discomfort
during your period.

There are many different kinds of birth control pills, patches etc.
All of which should be prescribed by a doctor, and you should decide
which is right for you.

generally speaking, once you start taking them as was mentioned but
bears repeating... they take time to work.

Somewhere I have read the reliablility of various types of
contraception.  Birth control pills, when taken properly, I *believe*
are the most effective form of contraception.  However, all forms of
contraception are close to 100% reliable *when used appropriately*.

If you're asking this question, you should probably read up on a
variety of other common questions.  There's a great website called Ask
Alice where you can read answers given by health experts to a variety
of similar questions.
