When do temps go triphasic

The initial rise may last for a few days, then the temperatures do rise again for the second time, typically 7 to 10 days after ovulation. Some women wonder if the second rise actually indicates pregnancy, but there is no scientific evidence that does support that triphasic curves reliably mean pregnancy.

The best way to figure out if one is pregnant is to watch for elevated BBT Thermal Shift beyond 14 to 15 days after ovulation without a period. In the fall-then-rise pattern, one observes that there happens to be a distinct rise and then temperatures drop or fall slightly again, and then immediately rise again for the rest of the existing cycle.

One needs to keep in mind that there are some circumstances where it might indeed be tough to distinguish fall-then-rise pattern from a chart with a random, outlier temperature. Some women do tend to observe a slight temperature dip right before ovulation and its subsequent temperature rise. One also needs to keep in mind that just because one experiences a dip, it does not necessarily mean that ovulation is coming. In other words, it is also possible that one can experience a dip but it is actually not followed by a sustained rise.

Unfortunately, not all thermal shifts are rather clear or obvious. One such indicator can be a triphasic chart!

A triphasic chart can be used as a possible sign of pregnancy, but how true or definite is it? Well, we will find that out and more in this article! So, what exactly a triphasic chart? Well, this chart is a BBT chart or basal body temperature chart women use to track their body temperature during three different phases of ovulation.

Ovulation is biphasic, which means the temperature variations can be seen pre and post-ovulation. However, there is a third phase in which the body temperature also changes, and that takes place around a week to ten days after ovulation.

This third phase is usually associated with a rise in the progesterone levels. Also, towards the second half of the menstrual cycle the luteal phase , progesterone is released to prepare the uterine lining for a fertilized zygote to attach or implant. Whether or not the fertilization takes place, the ripening of the uterine wall will happen after each ovulatory phase.

The increased amounts of progesterone hormones in the body result in increased body temperature. Therefore, triphasic basal body temperature BBT may not be a sure shot sign of pregnancy.

However, according to research, a chart indicating a triphasic pattern is more likely to be of a pregnant woman than a non-pregnant one. According to a study , among the , women whose temperatures were recorded in BBT charts, 12 per cent of all women whose charts showed triphasic patterns were pregnant. Therefore, if your basal body temperature chart shows triphasic patterns, the chances are that you could be pregnant!

The increase in the pattern can occur when you are pregnant, and when you are not. Is that normal?! I even took some rennie last night thinking it was indigestion, but it didn't help at all.

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.

In other words, your period is a few days late. While you're more likely to see a triphasic pattern on your chart if you're pregnant, seeing one doesn't mean you for sure are pregnant Get diet and wellness tips to help your kids stay healthy and happy.
