While nothing is 100% foolproof except total abstinence, using Birth Control will indeed reduce the risk of pregnancy, and in many cases, prevent it entirely. Some forms of birth control are far more reliable than others, so talk to your doctor and he or she can advise the best kind for you. There have been many improvements in the kinds of birth control that are available today, and contraception is used by millions of people. But if you want birth control to work, the key is to use it according to the instructions (the pill, the IUD, the contraceptive sponge and other methods are all used by the woman, and each method has its own instructions; condoms are used by the man, and here too, the condom must be used in the correct way). Some forms of birth control like condoms also protect against sexually transmitted diseases.
Male birth control methods include withdrawal of the male before ejaculation (the oldest contraceptive technique) and use of the condom, a rubber sheath covering the penis. The condom, because of its use as a protection against sexually transmitted diseases, including AIDS, has become a frequently used birth control device. Contraceptive methods for women include the rhythm method-abstinence around the most likely time of ovulation-and precoital insertion into the vagina of substances (creams, foams, jellies, or suppositories) containing spermicidal chemicals. The use of a diaphragm, a rubber cup-shaped device inserted before intercourse, prevents sperm from reaching the uterine cervix; it is usually used with a spermicide. Contraceptive sponges, which are impregnated with a spermicide, also are inserted into the vagina before intercourse and work primarily by acting as a barrier to the sperm. Intrauterine devices, or IUDs, are variously shaped small objects inserted by a doctor into the uterus; they apparently act by creating a uterine environment hostile either to sperm or to the fertilized egg. The birth control pill, an oral contraceptive, involves a hormonal method in which estrogen and progestins (progesteronelike substances) are taken cyclically for 21 or 84 days, followed by 7 days of inactive or no pills. The elevated levels of hormones in the blood suppress production of the pituitary hormones (luteinizing hormone and follicle-stimulating hormone) that would ordinarily cause ovulation. An oral contraceptive formulation that utilizes no inactive pills and is taken every day (and completely suppresses menstruation) also exists. Estrogen and progestins may also be delivered through the weekly use of a contraceptive skin patch or the monthly use of a vaginal ring (a flexible plastic ring inserted in the vagina); both slowly release the hormones they contain. Sterilization of the female, often but not always performed during a Cesarean section or shortly after childbirth, consists of cutting or tying both Fallopian tubes, the vessels that carry the egg cells from the ovaries to the uterus. In male sterilization (vasectomy) the vas deferens, the tubes that carry sperm from the testes to the penis, are interrupted. Sterilization, in most cases irreversible, involves no loss of libido or capacity for sex. No contraceptive yet devised is at once simple, acceptable, safe, effective, and reversible. Some, such as the diaphragm, condom, and chemical and rhythm methods, require high motivation by users; the pill, which must be taken daily, sometimes induces undesirable side effects, such as nausea, headache, weight gain, and increased tendency to develop blood clots. The IUDs, although requiring no personal effort or motivation, are often not tolerated or are expelled, and they sometimes, particularly if poorly designed, cause uterine infection, septic abortion, and other problems. If birth control fails (or is not used), doctors may prescribe several large doses of certain oral contraceptives as "morning after" pills; the high level of hormones can inhibit the establishment of pregnancy even if fertilization has taken place. Mifepristone, or RU-486, the so-called abortion pill, is effective within seven weeks after conception and requires close medical supervision. It was first approved in Europe and was tested in the mid-1990s in United States, where it was approved in 2000. Another experimental technique is immunization against human chorionic gonadotropin (HCG), a hormone secreted by a developing fertilized egg that stimulates production of progesterone by the ovary; the effect of the anti-HCG antibody would be to inactivate HCG and thereby induce menstruation even if fertilization occurred.

If used properly, the success rate tends to be in the ninety-percentile range. (No one method is completely successful, except abstinence.)
If taken every day as directed The Pill is 99.5% effective in preventing pregnancy.
From occurring yes, but it can't remove a pregnancy once it started.
Birth control helps you avoid pregnancy, not achieve pregnancy.
No form of birth control (except not having sex) is 100% effective
No
No. Birth control is intended to prevent pregnancy only. Birth control does not stop an existing pregnancy. It is not safe to take birth control while you are pregnant.
You shouldn't be taking birth control if you're not prescribed it. Birth control pills don't stop periods, they stop pregnancy.
Typically pregnancy or birth control.
It's possible to be pregnant, on birth control, and not know it. If so, you'll just stop the birth control when the pregnancy is discovered.
Just stop using it, but this may cause pregnancy.
You have to take birth control or you might have to get an abortion.
pregnancy
Well, don’t have sex, use birth control.
Birth control pills prevent pregnancy, they don't terminate it once it's a fact.
If by birth control you mean the pill (birth control being the name for all methods including condoms etc) it prevents a pregnancy occurring in the first place rather than stopping it once it has started.
No, but it can cause the baby to have heatlh problems. A high dose of birth control is offered as "the morning after pill." It's used to stop ovulation to prevent fertilization.
Birth control is not a 100% way to stop pregnancy and your period makes those chances even worse.
