BBT Chart
Using the Basal Body Temperature (BBT) chart:

  1. Download the BBT chart.
  2. Begin recording your temperature with a digital thermometer every morning upon waking before getting out of bed.
  3. A typical graph will show a slight drop in temperature just prior to ovulation followed by a rise between 0.3 and 1.0-degree farenheit, a result of rising progesterone after ovulation.  The temperature should remain elevated approximately 14 days and then drop, signaling the onset of menses.  If conception occurs your temperature should remain elevated and even jump to a third level on the graph.
  4. Note changes in vaginal mucus during the month.  It should be wet and slippery like egg whites around ovulation.  Please note these changes on your BBT chart.
  5. Note alterations in the cervix.  The rise in estrogen levels around ovulation cause the cervix to soften and move up and away from the vagina while the cervical opening enlarges.  Note any of these changes on your BBT chart as well.

Your BBT chart will allow us to determine when your body is ovulating, how much progesterone and estrogen you are producing and other areas of your cycle that need to be addressed.
