Choosing the right birth control can seem like a daunting task, especially with dozens of types to choose from.  Finding the method of birth control that is right for you can be influenced by a number of different factors including the effectiveness of the method, any related costs, how invasive it is, the complexity of the method, and  your religious or philosophical beliefs.  Here is a brief guide Natural Methods of birth control.

Natural Methods of birth control can be some of the most effective forms of birth control if used perfectly.  Some people prefer natural methods of birth control for religious or philosophical reasons or some people prefer them because there is no cost involved or purchases to be made. 

• Abstinence- Abstinence is the complete absence of sexual activity and it is 100% effective if perfectly adhered to.  The biggest disadvantage to abstinence is that you don't get to have sex.  Another disadvantage is for people who have been abstinent and suddenly decide to end their abstinence, they may not be prepared with an alternate form of birth control.  Some people who practice abstinence do not have vaginal sex but still have other kinds of sex such as oral, anal, or manual sex.  Having only these other types of sex, sometimes known as "outercourse" will not cause pregnancy themselves, but if semen gets on the outside of the vagina, it is possible for sperm to work its way into the vagina and cause pregnancy.
• Breastfeeding- Yes, breastfeeding.  After giving birth, the act of breastfeeding naturally causes a woman's body to stop producing the hormone that causes the ovary to release an egg.  Continuous breastfeeding is a very effective form of birth control for the first six months after childbirth.  Less than 1 in 100 women become pregnant when practicing continuous breastfeeding perfectly and only 2 in 100 become pregnant in the first six months after childbirth if they don't always exclusively breastfeed.
• Coitus interruptus- This is also known as the withdrawal method or "pulling out."  Believe it or not, when performed perfectly, pulling out can be a fairly effective method of birth control.  In perfect use, only 4 in 100 women will become pregnant using this method, but in typical use 27 in 100 will become pregnant.  This method is most effective if it is practiced by more experienced couples who know their own sexual responses and have great self control.  It is easy to perform coitus interruptus incorrectly, which is why it has such a high typical use failure rate and why it is often the "go to" example of poor birth control methods.
• Fertility Awareness Based Methods-There are several different types of Fertility Awareness Based Methods including the calendar method, cervical mucus method, standard days method, symptothermal method, and temperature method.  They all work by charting or tracking your menstrual cycle and understanding on which days you are most fertile and can become pregnant.  In perfect use only 3 in 100 women will become pregnant if they use fertility awareness based methods, but 24 in 100 will become pregnant in typical use of these methods.  One of the reasons the typical use failure rate is so high is that these methods work best for women with very regular periods and they take a lot of dedication and careful planning to be effective.
