Ideally, all women have usually straightforward and easy-to-read BBT Thermal Shift charts that do show their ovulation patterns very clearly, so everyone could conveniently know exactly when they happen to be fertile.
Fertility calculators would have been a thing of the bygone. Unfortunately, this is not really the situation. The most common type happens to be the biphasic curve or standard thermal shift pattern. In the biphasic curve, there are rather 2 phases: a clear set of low temperatures, to be followed by a distinct shift of at least two-tenths 0. This type of chart is the easiest to read and draw a cover line for you.
Although most of the women will experience the same kind of patterns within their own cycles, it is indeed rather normal to occasionally see some variation. This can mean that it took a little while for progesterone levels to rise high enough to cause a shift in temperature, or that the body responded slowly to the increase in progesterone levels.
Not necessarily. There are plenty of examples of women who conceived on cycles where they had a slow rise after ovulation. If your temperatures are low throughout the entire luteal phase, or if your luteal phase is less than 10 days, these could be possible signs of low progesterone, which could make it harder to conceive. But a slow rise, absent any other symptoms, does not indicate a fertility problem. Even with a slow rise, a temperature pattern usually becomes apparent after a few days.

Birth Control. The definition here is just for the purposes of analysis. When looking at non-pregnancy charts, they found that only 4. So, based on this data, a chart indicating a triphasic pattern is three times more likely to belong to someone who is pregnant. There is a very important fact to point out here, in case you missed them:. Or, to put it another way, if you looked at the pregnant BBT charts of women, just one or two of them would show the triphasic pattern.
As the statistics above stated, roughly 5 out of every charts 4. What causes that third temperature shift? For a non-pregnancy chart, a triphasic chart could be caused by a difference in your bedroom temperature, a slight illness not enough to cause a fever but maybe a slight temp rise , or your hormones getting overly excited about not much.
What if you are pregnant? In that case, the triphasic pattern could be caused by further increases in the hormone progesterone. It is the hormone progesterone that causes the original shift up at the time of ovulation. The theory is that implantation of an embryo triggers increased production of the hormone progesterone.
That sudden boost may cause another shift up in temperature. Any excuse to take an early pregnancy test , right? Or, maybe not. There are many good reasons not to take an early pregnancy test. You might think that a triphasic pattern is a good reason to go ahead and test before your period is late. Keep in mind, however, that pregnancy tests look for the pregnancy hormone hCG —and not progesterone. Consider holding off on testing until either your period is late or you show 16 days of high temperatures on your chart.
Sixteen days of high temperatures is the best sign of pregnancy you can find on a BBT chart. Basal body temperature charting is an excellent way to get to know your menstrual cycle better, detect ovulation day, and learn what your most fertile days of the month are.
You may be tempted to look for signs of pregnancy on your chart, like the triphasic pattern, but the most reliable sign of pregnancy on a BBT chart is that your luteal phase passed 16 days.
