In most cases, you are able to see a biphasic pattern on your chart after ovulation has taken place. That is, you will have lower pre-ovulation temperatures and higher post-ovulation temperatures. Your temperature may rise slowly in increments, or quickly, or it may even rise and fall slightly over several days. The rise in temperature is usually about 0.4 degrees Fahrenheit or 0.2 degrees Celsius, but the rise may be as slight as 0.2 degrees Fahrenheit or 0.1 degrees Celsius or even less in some cases. Great variability is possible.
More important than the value of the rise, is the overall pattern of the chart. Fertility Friend helps you determine ovulation based on the pattern of the chart and all fertility signs. Because there are no standard rules that can apply to everyone, Fertility Friend has been tuned and trained to recognize a wide range of ovulation patterns on your chart, based on all your signs.
