subject: Basal Body Temperature Charting: What is it and why should you do it? [print this page] When you have ovulated, you can expect to see a spike in temperature ranging from about .5 to 1.6 degrees. You are most fertile in the 2-3 days before ovulation, and up to 24 hours after ovulation has occurred. You will know for sure that you have ovulated when you have 3 consecutive days of increased temperatures. Of course, three days after ovulation is too late to become pregnant, so it's best to have intercourse as soon as you notice a temperature spike. You may need to chart for a couple of months to see when you tend to ovulate. Try to have intercourse every day in the days leading up to ovulation. To identify your exact fertile window, and for the best way to get pregnant, use a basal thermometer in conjunction with an ovulation predictor kit. If you do not see a consistent rise in temperature in the second half of your cycle, it is possible that you are not ovulating. In this case, you can bring your basal body temperature chart to your doctor to seek possible treatments.
