Basal Body Temperatures – a how to for a fertility calendar

by Fay Porter

So many couples are forced to go to other means of helping conception along. Not always is the equation have lots of sex + right timing = baby as easy to accomplish for some as it is others.


Sometimes, couples are forced to try other methods along with the equation for baby to help conceive their child. Tracking the basil body temperature is one of the many methods used today.

Basal Body Temperature (BBT) is a very natural way of charting your more fertile days by temperature, therefore increasing your chances of the ‘right timing.’ The concept behind BBT is very simple: the woman’s temperature is generally lower before ovulation and higher afterwards. Generally before ovulation, a woman’s BBT is between 97 and 97.5 degrees Fahrenheit whereas after ovulation, the temperature rises to 97.6 to 98.6 degrees.

To effectively use the BBT method, a woman must take her temperature for 4 minutes every morning immediately after waking up. By using a piece of graph paper, she can record her temperatures, noting a fall in temperature right before ovulation. Immediately after ovulation, progesterone is released, a hormone related to pregnancy, will cause the body’s temperature to increase, holding it at the higher level until the next time for ovulation.

It might take the woman up to a year to be able to accurately read her BBT chart, but it should not take that long.

The main drawback to the BBT method is that there are outlying factors that can influence your BBT like alcohol, lack of sleep or irregular cycles. Some women have even been known to ovulate twice in one month.

BBT does work, but it always works more effectively if used with other natural planning methods like the calendar method and the mucus secretion method.
