Stop using birth control
Seems obvious, but some forms of birth control have more lasting effects than others. According to the American College of Obstetrics and Gynecology, if you're taking birth control pills, continue to the end of your current cycle before stopping the pills, then start trying the next month (some doctors recommend waiting an additional month or more — check with your gynecologist). Makers of Norplant say that the contraceptive sticks wear off three days after they are removed, while the manufacturers of Depo-Provera claim it takes 12 weeks for the progestin (contraceptive hormone) to leave your body. If you use condoms, a cervical cap, or a diaphragm, all you need to do is put them away.
