It is the most effective way to prevent transmission of HIV. It's important to remember that birth control pills do not prevent sexually transmitted infections. If there is a chance that you or your partner might have an STI, you should use a barrier method even if your birth control is working to prevent pregnancy. If you're taking birth control for reasons other than contraception, including acne, polycystic ovary syndrome, or endometriosis, it could take 2 or more months to begin taking effect.

The exact length of time will depend on your body and the severity of your condition, so it's best to talk to your doctor to understand better how birth control will affect you.

However, when it comes to preventing pregnancy, with a little information about your cycle and the type of birth control you're using, we can narrow down when your birth control starts being effective. Some methods even begin working immediately. The time it takes for a birth control pill to work depends on the type of pill and where you are in your menstrual cycle when you first take it.

If your birth control pill is a combination pill that contains both estrogen and progestin, the pill will be effective right away as long as you take it within 5 days of the start of your period. If you start taking a combination pill during any other part of your menstrual cycle, the pill will begin to work after 7 days. Make sure to use a back-up barrier method during those 7 days. If you take a birth control pill that only contains progestin, it will take effect 48 hours after taking the first pill, no matter where in your cycle you begin taking it.

During those 2 days, you should use a back-up barrier method to prevent pregnancy. You have to wait to have sex after beginning the pill or use a condom because the medication mainly works by preventing ovulation—the ovaries are kept from releasing an egg, so there'll be nothing for sperm to fertilize.

Depending on the type of pill you use, it might also thicken the mucus in your cervix making it difficult for sperm to swim through and get to the egg. Birth control pills can also prevent the lining of your uterus from thickening which is necessary to provide a fertilized egg a place to implant and grow. When you have your period, the lining of the uterus and the egg released at the start of that cycle wash away and out of your body, so there's no egg to fertilize, and your uterus isn't ready to accept a fertilized egg even if there was one.

At other points in your cycle, your body has already released an egg, and your uterus prepares for a potentially fertilized egg. Until the hormones in your birth control pills begin to take effect and create changes in your body, there is a chance you could become pregnant. Therefore, it's essential to wait for 2 to 7 days, depending on the type of pill you use, or use a backup form of birth control until your pill has time to take effect fully.

If you're cracking open your first pack of birth control pills, welcome to the club! Or perhaps you've been struggling to sort out which birth control method works best for you and are about to try yet another pill with a different blend of hormones.

Either way, getting new birth control can be an exciting sort of experiment — at least, it's helpful to think of it that way. There are plenty of good reasons why people go on birth control , but the biggie is, of course, to prevent pregnancy. So, how long does it take for the pill to kick in? It's a little complicated, and figuring it out starts with understanding exactly how pills do their thing in the first place. That means your ovaries won't release an egg.

There are basically two kinds of hormonal birth control pills: a combination pill, which contains a blend of estrogen and progesterone, and a progesterone-only pill, which — you guessed it — only contains a synthetic version of progesterone. They work essentially the same way and will "override your body's natural surges, to create a cycle yourself," Dr. Shirazian says. Once you reach 35, discuss birth control options with your healthcare provider. Progestin-only pills may no longer be the best choice for you.

If you smoke, you must find another method of birth control to lower your risk for complications. Combination pills are generally safe for nonsmokers of any age. But those who smoke should avoid combination pills regardless of age. Estrogen increases the risk of blood clots. As a long-term birth control method, birth control pills require consistent use. Take your birth control pills exactly as prescribed.

Taking birth control pills may lead to breast tenderness and nausea for some people. You may be able to reduce these side effects by taking your pill before bedtime. If you experience no problems during your first year of taking birth control pills, you can probably continue using them without issue for many years.

One common concern about long-term use of birth control pills is how it affects your cancer risk.

Long-term use may slightly increase your risk for breast , liver , and cervical cancers.
