Birth control methods prevent pregnancy from occurring. Several methods are available, including birth control pills; barrier methods such as condoms, diaphragms and cervical caps; implantable devices such as intrauterine devices, or IUDs; natural family planning; and abstinence. The only birth control method that provides 100 percent protection against pregnancy is abstinence. Every other method relies on the individual using the method properly for effectiveness.
Step 1
Take your birth control pills every day, at the same time each day, exactly as your doctor prescribes. Planned Parenthood explains that birth control pills supply hormones to the woman's body, and that taking them at the same time each day will maintain a constant level of the hormones in your body. When birth control pills are taken in this manner, they are extremely effective and prevent pregnancy in 99 out of 100 women annually who use them.
Step 2
Avoid taking medications that may decrease the effectiveness of birth control pills, or use a backup method if necessary. Some medications such as antibiotics, antifungals, anti-seizure drugs and herbal supplements such as St. John's Wort can decrease the effectiveness of birth control pills. If you are prescribed any of these medications, it is likely that your birth control pills will not work properly for the time period that you are on the medication. Use a backup method such as a condom or contraceptive foam during that time.
Step 3
Use a condom each and every time you have sexual intercourse if condoms are your chosen method. The condom should be put on before intercourse begins, and it should be properly fitting. Condoms should be used prior to their expiration date, and as MayoClinic.com explains, should be stored in cool locations. Condoms should not have any visible tears, holes or defects, and a new one should be used each time. Inspect the condom upon removal to ensure no tears or holes have occurred during usage.
Step 4
Monitor your monthly menstrual cycles for consistency, or encourage your partner to monitor her cycle. While some birth control pills can limit the number of periods a woman gets per year, most pills still allow for a monthly period to occur when used properly. If pregnancy has not occurred, your period should come on time each month. If it does not, consult with your health care provider for options.
