Will I be able to get pregnant when I want to?
If you want to get pregnant anytime soon, you may want a method that you can stop quickly. Such methods include short-acting hormonal methods or barrier methods. If you want to keep from getting pregnant for a longer time, you might choose a long-acting method, such as an IUD.
You might want different types of birth control at different times in your life. If you know that you don't want to get pregnant ever, you may prefer a lasting method, such as sterilization.
