BBT Chart – Free to Download and Use
One of the changes that ordinarily takes place in a woman’s body, as part of her menstrual pattern, is that her body temperature is lower during the first part of the cycle. In most women, it usually rises slightly with ovulation and remains up during the second part half of her cycle until just before her next period. Recording each day’s basal body temperature helps to indicate when ovulation has occurred.
Charting for several months will give you a pretty good idea of where in your cycle you are ovulating. Using your BBT chart to help you predict when you are ovulating will help you time intercourse so you will have a better chance of getting pregnant.
