Many popular birth control methods are very effective if taken perfectly, but that effectiveness goes down drastically with typical use. Perfect use means that the method is used consistently and correctly. This is not as easy as it sounds for many people despite their best intentions. For this reason, medical researchers have studied the effectiveness and failure rates of the various birth control methods. For example, birth control pills are 99.7% effective with perfect use. But in fact, 9% of women will become pregnant within the first year of using the pill and only 91% of women using the pill will have the desired effect of not becoming pregnant with typical use. Even more drastic is the difference between the reported 98% effectiveness of male condoms with perfect use when the reality is that 18% of women using male condoms will become pregnant within the first year and only 82% will not become pregnant with typical use. Many women and their partners may not be aware of these differences.
This distinction is important for two reasons:
First, you will want to consider this when selecting the right birth control method(s) for you. To select the right birth control method(s) for you, prospective users (women and their partners) should be aware of the effectiveness of all the available methods. In addition, you will want to be aware of how long the method works/how frequently you have to use it and potential side effects. More information to come on this to help you make important decisions.
Second, you will want to use your selected method(s) of birth control consistently and correctly. Now you may be wondering what it means to consistently and correctly use your birth control method. Let’s use the most popular methods of birth control as examples again.
For birth control pills, this means taking a pill consistently every day and not missing days between pill packs. Pills are taken correctly if taken at the same time every day. Studies have shown that women may be missing up to 5 pills per cycle, on average, and many women have gaps between pill pack refills at the pharmacy. It’s important to look at your daily routine and find a time when it would be easy to take your pill at the same time every day. Is it easiest to take your pill… First thing when you wake up? As your morning coffee is brewing? When you’re feeding the dog? When you brush your teeth in the evening? Right before bed? If you don’t have a daily routine or can’t find a time to consistently take your pill at the same time, the pill may not be a good birth control choice for you and there are other options that don’t require daily action on your part. Once you find a time that works, you can set up convenient reminders. Bedsider offers a free service to send you convenient text message reminders for your pill, patch, ring, or injectable birth control method. Set up your reminder now. Not only are these messages helpful reminders, they are also very entertaining:

For condoms, you need to be sure to use a condom consistently with each act of sex and correctly following these instructions from Planned Parenthood:
