Thanks for your question. I recommend that you discuss your question further with your doctor
. Natural family planning is an intermittently en vogue idea that appeals to those who do not want to add
hormones or other "unnatural things" to their body. Unfortunately, most of the data agrees that it is not as effective as hormonal contraception. While this may be unpopular to say, it is somewhat difficult for most women with irregular periods and those with other acute situations such as breast feeding to effectively predict how and when they will ovulate. Additionally, it is a method that requires a high degree of responsibility and involvement on the part of the person who is attempting to use this method. While hormonal contraception is not perfect, it is much more effective for most people, at least speaking statistically. IUDs in particular are quite effective at preventing pregnancy, with one of the most effective and impressive rates of preventing pregnancy around. As with all types of birth control
, however, there are pros and cons to IUDs as well. Whatever you decide, it is important to be well educated and review appropriate resources (rather than a select few that some groups may choose to present). Your OB can help. Please speak with your doctor.
