BASAL TEMPERATURE CHART

basal temperature chart

A daily chart of temperature obtained upon awakening. Some women are able to predict the time of ovulation by carefully analyzing the character and rhythm of the temperature chart. This information and other data can be used to establish that the woman is ovulating. Use of this method to control conception by predicting time of ovulation is unreliable in most cases.
