&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Billings Ovulation Method&amp;#039;&amp;#039;&amp;#039; is a form of [[Natural family planning|natural family planning]] that was developed by Drs. John and Evelyn Billings of Melbourne, Australia. The method is based on the observation and charting of [[Cervical mucus|cervical mucus]] to determine a woman&amp;#039;s fertility.&lt;br /&gt;
&lt;br /&gt;
==History==&lt;br /&gt;
The Billings Ovulation Method was developed in the 1950s by Drs. [[John Billings|John]] and [[Evelyn Billings|Evelyn Billings]]. The couple were inspired to create a natural method of family planning after observing the lack of options available to Catholic couples following the [[Papal encyclical|Papal encyclical]] &amp;#039;&amp;#039;[[Humanae Vitae]]&amp;#039;&amp;#039;, which prohibited artificial contraception.&lt;br /&gt;
&lt;br /&gt;
==Method==&lt;br /&gt;
The Billings Ovulation Method involves the woman observing and charting changes in her cervical mucus. The presence and consistency of this mucus can indicate the various stages of the [[Menstrual cycle|menstrual cycle]], including ovulation. By avoiding intercourse on days when fertile-type mucus is present, couples can avoid pregnancy.&lt;br /&gt;
&lt;br /&gt;
==Effectiveness==&lt;br /&gt;
Studies have shown that the Billings Ovulation Method can be up to 99% effective in preventing pregnancy when used correctly. However, the method requires careful instruction and consistent charting, and its effectiveness can be reduced if these are not adhered to.&lt;br /&gt;
&lt;br /&gt;
==Criticism==&lt;br /&gt;
Critics of the Billings Ovulation Method argue that it is not as reliable as other forms of contraception, and that it requires a high level of commitment and understanding from both partners. Some also argue that it is not suitable for women with irregular menstrual cycles.&lt;br /&gt;
