How well does it work?

There are two ways to rate how well birth control methods work. You can say how good they are if people use them perfectly. Or you can look at what happens in real life – because people aren’t usually perfect!

Why is it ‘typical’ not ‘perfect’?

If you need to remember to do something regularly, like take a pill or stick on a patch, the score for ‘typical use’ is a lot lower than for ‘perfect use’. Typically, people sometimes forget!

And with things like condoms or diaphragms, people sometimes make mistakes putting them on or inserting them.

What does ‘failure rate’ mean?

If 100 women use a birth control method for a year, the number of them who get pregnant anyway is the ‘failure rate’.

For example, if a hundred women use condoms for a year each time they have sex, typically 14 of them will get pregnant. So the failure rate is 14 per cent.

(That’s including all the mistakes – if they used the condoms perfectly, only three of them would probably get pregnant by accident.)

By way of comparison, if 100 women have sex for a year without using birth control, on average 85 of them will get pregnant. So you could say using no birth control has a ‘failure rate’ of 85 per cent.

100 per cent certainty

The only way to be 100 per cent sure to not get you or your partner pregnant is to not have sex and abstain.


Hi Verah, It maybe useful to discuss with you doctor or health provider to find a method that will work well for you. Also, remember all the methods have a failure rate hence the need to use two methods at a time for instance the pill combined with a condom.

Hi is it advicable to use birth control before have a child eg the injections and coils.

Hi Moh, Yes you can use birth control at any time before or even after you have children. When you want to have children you simply stop using the birth control method you are on and you should be able to get pregnant.

Hi Emma, There are number of reasons that may lead your periods to delay including sports, change in diet and environment, use of contraceptive or even hormonal imbalances. A missed period could also be an indicator of pregnancy if you had unprotected sex. Give it time to see if they will come. With regard to the abdominal pain, it maybe important to seek medical attention for check up and treatment. Lastly, there is nothing wrong with feeling like having sex as long as it is safe.
