Yes. Although birth control pills have a high success rate, they can fail and you can get pregnant while on the pill. Certain factors increase your risk of getting pregnant, even if you’re on birth control. Keep these factors in mind if you’re sexually active and want to prevent an unplanned pregnancy. Show
Success and failure rates of birth control pillsBirth control pills are 99 percent effective with “perfect use,” which means taking the pill at the same time every day without missing a dose. “Typical use” is how most women take the pill, and then it’s about 91 percent effective. Both combined oral contraceptives and progestin-only pills (also known as the mini pill) have a typical failure rate of 9 percent. Many women accidentally miss a dose or forget to start a new pack of pills. When that happens, the chances for an accidental pregnancy go up. The Pregnancy Quiz: Am I Pregnant? » What causes birth control to failCertain conditions or behaviors can increase the likelihood that your birth control won’t be as effective at preventing pregnancy. If you can’t remember to take your pill at the same time every day, you increase your risk of pregnancy. Birth control pills are designed to maintain a constant level of hormones in your body. If you skip or miss a dose, you hormone levels can drop quickly. Depending on where you are in your cycle, this may cause you to ovulate. Ovulation can increase your chances of becoming pregnant. Reckless alcohol consumption can also cause birth control failure. While under the influence, some women may forget to take their pill at the correct time. If you vomit too soon after taking your pill, your body may not be able to absorb any of the hormones. This can result in a drop in your hormone levels, which could trigger ovulation. Taking another medication or supplement at the same time as your birth control pill can also affect the pill’s effectiveness. How to prevent birth control failureKeep these tips in mind if you’re on birth control and want to prevent pregnancy. Time it rightMake sure you take your birth control pill at the same time every day. Set a reminder on your phone or watch if you need to. You may also consider taking the pill with a specific daily activity, such as during lunch or dinner. If you take progestin-only pills, you should be especially careful about taking the pill at the same time every day. If you’re late with a dose or skip one altogether, your hormone levels can drop very quickly. This could cause you to ovulate and that greatly increases your chances for getting pregnant. If you miss a dose, use a backup method or avoid sex for the next week. To be extra cautious, use a backup method, such as a condom, or avoid sex for the next month. Take the placebo pillsCombination pill packs typically contain three weeks of active pills that contain hormones and one week of inactive, or placebo, pills. Although it isn’t medically necessary to take the placebo pills, doing so can help you stay in your routine. If you choose to skip the placebo pills, there’s a chance that you may be late in starting your next pill pack. This can interrupt your body’s expected level of hormones and cause you to ovulate. Ovulation increases your chances of being pregnant. Don’t mix medicationsSome prescription and over-the-counter medications may interfere with your birth control’s effectiveness. Before you begin taking a new medicine, ask your doctor or pharmacist if you should use a backup method of protection while taking this new medication. Although some antibiotics have been anecdotally connected to unplanned pregnancies, research has largely debunked this connection. A possible connection with reduced birth control effectiveness is only recognized with one type of uncommon antibiotic called rifampin. Don’t use St. John’s wortSt. John’s wort is a popular over-the-counter herbal supplement that can affect liver metabolism. This supplement can interfere with birth control’s effectiveness. You could experience breakthrough bleeding and possibly an unplanned pregnancy if you take the two medicines together. Talk with your doctor about any additional measures you should take, including a backup protection method while you’re taking St. John’s wort. Knowing what can make your birth control ineffective and how you can increase your chances of successfully avoiding pregnancy will help you make the best decisions for you and your lifestyle. Different methods of birth control can be highly effective at preventing pregnancy, but birth control failure is more common than most people realize. Here is a chart displaying birth control failure rate percentages, as well as common risks and side effects. Birth Control Failure ChartNote that the failure rates are for the average use of the method. Consistent and correct use may further decrease your chances. For specific hormonal birth control methods, the risk of pregnancy for correct use should be listed in the instructions/details. When speaking of hormonal birth control, it is important to consider both the high success rate and the ethical concerns of the third act of the birth control: changing/thinning the lining of the uterus to prevent implantation. Since this can stop an already begun pregnancy from continuing, it is said to have abortifacient qualities. This will be an action of any of the hormonal birth control methods listed.
