==How did THAT happen?== I have a friend whose husband did not want any children at all. So she took the Birth Control pill and he used condoms every single time they had sex. Well, they had two children, a boy and a girl. She said that she has no idea how that happend, but it did. A paternity test might offer a clue. ==General answer== If you know the failure rates for both methods you can calculate the failure rate for combining them, theoretically. Let's say Method A is 90 percent effective. That means that ten percent of the women using the method will get pregnant in any one year. Let's say Method B is only 80 percent effective, so its failure rate is 20 percent per year. The failure rate of both methods employed together, however, is the product of the failure rates, 0.1 x 0.2, or 0.02. Subtract that from one, and you get the effectiveness of the combination: 0.98. Pretty darn impressive. Of course, this assumes that the methods are compatible. Some non-latex condoms are not compatible with spermicides, so using them together could increase the failure rate.

Should I use condoms or birth control?

You should definitely use something. Condoms prevent pregnancy and STDs (sexually transmitted diseases). Birth control pills only prevent pregnancy. It is possible to use both, for double protection. If you are on birth control it is a good idea to use condoms too to protect against STDs. If you do not regularly have sex, you may prefer to use condoms, but if you regularly have sex then you may prefer birth control pills. With birth control pills you would need to remember to take them every day at around the same time. Even missing just one pill can lead to pregnancy. With condoms you would need to remember to have some ready to use. Thee are many different types of birth control pills and also many types of condoms. To find out more about birth control, speak to your doctor or nurse. To discuss both options and which would be best for you then I suggest going to an advice centre where they can give you information that will help you to make a decision. You could also discuss it with your doctor or nurse.
