So I'm not talking about any old thermometer here, although a regular digital one would probably work. I'm talking about a basal body thermometer which is more accurate than a regular glass thermometer. It's an ovulation showing, period predicting wonder! Well, not a "wonder" really, but it sure is wonderful!
Here's a little background information on the subject:
Basal body temperature is the lowest temperature attained by the body during rest. It is generally measured immediately after awakening and before any physical activity has been undertaken. In women, ovulation causes an increase of one-half to one degree Fahrenheit in basal body temperature (BBT); monitoring of BBTs is one way of estimating the day of ovulation. Most women have lower temperatures before ovulation (caused by estrogen), and higher temperatures afterwards (caused by progesterone). This is known as a biphasic pattern.
Anyway, we're planning to start a family soon so I thought I'd go ahead and see what I could find out about my cycles by tracking my BBT. Having done my research, I knew what my chart was "supposed" to look like, but I really didn't expect to see it. I mean, how can a thermometer give me all this information?!?! So I tracked my BBT and was pretty shocked (amazed?) that it really "worked"! Here's what my first chart looked like:
