What does it mean to be triphasic?
Triphasic refers to the thermal shifts that occur in your basal body temperature. A triphasic pattern is when three levels of temperatures or thermal shifts are seen. The first level is pre-ovulation, then post-ovulation and the second rise is 7-10 days after ovulation.
Your basal body temperature (BBT) will typically be between 96.5-97.5 degrees before you ovulate. After ovulation your BBT should range from 97.5-98.6. In a triphasic pattern there will be an increase in temperature seven to ten days after ovulation. This increase, often referred to as a thermal shift happens because of the increased progesterone levels from the embryo.
Sometimes this third increase in BBT will not mean you are pregnant. Also, some women that are pregnant will not be triphasal. Like all signs of pregnancy you can only guess that you might be pregnant until you are able to confirm the pregnancy.
Charting your BBT can help you determine when you are best able to get pregnant and can be very helpful when you are trying to conceive. BBT can be measured by either a glass or digital thermometer, as long as it is a basal thermometer. Glass thermometers tend to be a little more accurate.
