Pregnancy is an exciting time for expectant mothers and a big moment in a woman’s life. Many expectant mothers are eager to understand their bodies and keep track of their various changes during pregnancy. One way to do this is to keep track of the body’s temperature with a Basal Body Temperature (BBT) chart. The result is a unique BBT chart that provides a visual representation of changes in a mother’s body. In this blog post, we will review a few examples of BBT charts and explore the basics of how BBT charts can be used to track a woman’s body during pregnancy.
With a better understanding of how BBT charting works, pregnant women can make more informed decisions about their pregnancy health and wellness. We will review how to record, read and interpret BBT chart data and how to use the data to monitor health and wellbeing during pregnancy. We will also discuss the advantages and disadvantages of using
What causes triphasic temperature shifts
On a basal body temperature chart, what is the most likely reason for the third temperature change?
The triphasic chart in a non-pregnant woman’s chart could be brought on by the fluctuating bedroom temperatures, hormones getting excited, or a minor illness that only raises body temperature slightly rather than producing a fever.
For a pregnant woman, the triphasic chart may be caused by an increase in the progesterone hormone in the body. Hormone progesterone causes the normal temperature to increase during the ovulation period. Progesterone will trigger your uterine lining to prepare for embryo implantation after fertilisation. It also suppresses ovulation, the reason why you cannot get pregnant when you have already conceived. It also ensures that the endometrium does not shed when you already have an embryo or baby in the uterus.
The idea is that the implantation of the embryo will stimulate and boost the production of progesterone, and the abruptly elevated levels of the hormone will result in another shift in body temperature.
Reliability of triphasic charts
One fertility charting online software company conducted an informal analysis to evaluate their website’s basal body temperature charts and see if the triphasic patterns may indicate pregnancy. This was not peer-reviewed scientific research, but the results were interesting.
They did consider the triphasic pattern to be the second significant upward temperature shift of about 0 during their informal analysis. 17℃, occurring about seven days after ovulation. (Generally, a triphasic chart lacks a clear, unambiguous definition. There may be disagreement among those who compare and exchange BBT charts regarding whether the patents qualify as triphasic or not. Our definition here is for the analysis. ).
When they analysed more than 149,000 BBT charts, the researchers realised that 12% of the pregnancy charts revealed a triphasic pattern Looking at the non-pregnancy chart, they discovered that 4 5% of them showed a triphasic pattern. Triphasic shifts were detected on average on the 9DPO.
How to Detect Pregnancy Using Your BBT Chart
1. Your body temperature will be lower from the start of your period until ovulation.
2. You’ll experience an increase in your basal body temperature at midcycle (or possibly later if your cycles are erratic).
3. Your temps will stay high until they drop again. You will know you have ovulated once your temperatures increase for at least 3 days and remain elevated.
4. It is highly likely that you are pregnant if your temperature remains high for longer than 18 days after ovulation.
