Birth control is used to prevent pregnancy. There is a variety of birth control options available, and what is right for one person may not always be the right choice for another. Your healthcare provider will be able to guide you in choosing the right kind of birth control for you. Show
If you opt for certain methods, such as hormonal birth control, it can take time for the medication to become effective at preventing pregnancy. In the interim, you will want to use backup birth control (condoms) to prevent an unplanned pregnancy. This article will review the different kinds of birth control and explain how soon they become effective at preventing pregnancy.
Methods and Types of Birth ControlThere are several birth control options for both men and women. Deciding which one is right for you may include factors like efficacy, convenience, and affordability. ImplantsThe birth control implant, sold under the brand name Nexplanon, is a thin rod that is inserted under the skin in the upper arm by a doctor. It contains a hormone called progestin that slowly releases throughout the body over a three-year period. InjectionsThe "shot," or injectable form of birth control sold under the brand name Depo-Provera, is injected into the buttocks or the arm by a healthcare provider. This progestin-only form of birth control prevents pregnancy for 13 weeks or three months. IUDsWith an intrauterine device (IUD), a doctor inserts a small, T-shaped device inside the uterus that works to prevent pregnancy for a certain number of years. There are two types of IUDs: hormonal and nonhormonal. The nonhormonal copper IUD (sold under the brand name ParaGard) is effective for up to 10 years. There are four types of hormone-releasing IUDs approved in the United States. These all contain progestin-only:
PatchesThe birth control patch is a method of birth control that is worn externally, on the buttocks, lower abdomen, or upper parts of the body. The patch releases both estrogen and progestin into the blood. A new patch is applied to the body once a week for three weeks. On the fourth week, a patch is not worn, and your period occurs. PillsCommonly known as "the pill," birth control pills are taken by mouth daily. There are two types of birth control pills:
RingsThe hormonal vaginal contraceptive ring NuvaRing (eluryng) is worn inside the vagina. It releases both progestin and estrogen into the body. The ring is worn inside the body for three weeks. On the fourth week, it is removed and your period occurs. A new ring is then put back in. Condoms, Diaphragms, and SpermicideCondoms, diaphragms, and spermicide are all barrier methods of birth control. The male condom is worn on the penis and stops sperm from entering the vagina during penis-in-vagina sex. The male condom also protects against STDs (sexually transmitted diseases) and human immunodeficiency virus (HIV). The female condom is inserted into the vagina to prevent sperm from entering the body during penis-in-vagina sex. The female condom can be inserted up to eight hours before intercourse. The female condom may also help guard against STDs. The diaphragm is a shallow cup that is placed inside the vagina to block sperm from entering the body. Diaphragms come in different sizes and a doctor must do a fitting to find the appropriate size. Diaphragms should be used with a spermicide. Spermicides (which work to immobilize sperm) come in a cream, foam, gel, suppository, or tablet form. The spermicide is inserted into the vagina no more than an hour before intercourse occurs. The spermicide is left in the vagina for at least six to eight hours following sex. Tubal Ligation and VasectomyTubal ligation, or having your "tubes tied," is a surgical procedure in which the fallopian tubes (which connect the ovaries to the uterus) are cut or sealed off so fertilization of a sperm and egg can't occur. Vasectomy is a procedure that cuts off the tubes that carry sperm to the penis. After a vasectomy, there will be no sperm in the ejaculate. A vasectomy is an outpatient procedure performed under local anesthesia. Following the operation, tests are performed to count sperm and ensure the sperm count is at zero. This can take roughly 12 weeks. How Long Does It Take for Birth Control to Work?How quickly birth control works varies based on birth control method. ImplantsIf the implant is inserted during the first five days of your period, you are protected from pregnancy immediately. If it is inserted at any other time, it will take a week to be effective. InjectionsIf the injection is given within the first week of your period starting, you are immediately protected from pregnancy. If the shot is given within seven days of an abortion or miscarriage, protection is immediate. If the shot is given within three weeks of giving birth, protection is immediate. At all other times, it will take a week for the injection to be completely effective at protecting against pregnancy. IUDsThe copper IUD Paraguard is immediately effective at protecting against pregnancy (and is effective as emergency contraception if inserted within five days of having unprotected sex). All hormonal IUDs are immediately effective if they are inserted within seven days of the start of your period. If you have the IUD inserted at any other time, it will not be effective for one week. During that time, you should use backup birth control (condoms) or abstain from sex to prevent pregnancy. PatchesIf applied during the first five days of your period, the patch immediately protects against pregnancy. If applied at any other time, it will take a week before the patch protects against pregnancy. PillsIf you start the combination pill in the first five days of your period starting, you are immediately protected against pregnancy. At any other time, it will take a week to be fully protected. If taking the progestin-only pill, protection will be effective after 48 hours. The Slynd progestin-only pill offers immediate protection if taken on day one of your period. RingsIf the ring is inserted within the first five days of your period starting, it will work immediately. If it is inserted at any other time, it will take a week before it is effective. Condoms, Diaphragms, and SpermicideIf worn correctly from start to finish of sexual intercourse, condoms provide immediate protection against pregnancy and STDs. If used correctly, a diaphragm can offer immediate protection once inserted. Not all spermicides are effective immediately. Some need to be inserted into the vagina 10–15 minutes prior to sex. Some spermicides are only effective for an hour after insertion. Follow the packaging instructions carefully to optimally prevent pregnancy. Tubal Ligation and VasectomyTubal ligation is immediately effective at protecting against pregnancy. Vasectomy can take about 12 weeks to be effective. Backup contraception (condoms) should be used until your healthcare provider confirms that your ejaculate no longer contains sperm. Side Effects and Symptoms of Birth ControlAll methods of birth control can have side effects. However, side effects from hormonal birth control methods, such as the implant, patch, and the pill, are often temporary and usually go away within a few months, once the body has adjusted to the hormones. Side effects of the implant may include:
Side effects of the injection may include:
Side effects of the IUD may include:
Side effects of the patch may include:
Side effects of the pill may include:
Side effects of the ring may include:

When to See a Healthcare Provider About OptionsNever be embarrassed to discuss issues like sex or birth control with your healthcare provider.

A Word From VerywellThere are a number of birth control options available, each with its own advantages and disadvantages. Some may have side effects, and the efficacy of protection against pregnancy varies among different kinds of birth control.
