Many have heard the term "basal body temperature". Only not everyone knows what it is. Most often, women planning a pregnancy face the concept. Next, we will study the basal temperature before menstruation, during them and after. We will have to get acquainted with the causes of deviations from the norms, as well as with ways to measure temperature.
Definition
Basal temperature is an indicator that can indicate the course of certain processes in the body. The concept, as we have already said, is faced by women planning a pregnancy.
The mentioned component helps to determine when critical days come or ovulation occurs. The main thing is to know what the basal temperature should be. Before menstruation, she is one, after them - another. And this will have to be remembered under any circumstances.
Menstrual cycle and changes
Unfortunately, it is impossible to find a definite answer on the topic under study. The organism is influenced by external factors. What's more, women are constantly menstruating.
It can be conditionally divided into 3 phases:
- follicular;
- ovulatory;
- luteal.
In all these intervals, the body temperature will be different. And this is quite normal.
Follicular stage
What is the basal temperature before menstruation is normal? Consider all possible scenarios.
In the menstrual cycle, the first stage is follicular. This is the period of maturation of the egg in the follicle. It comes during critical days and lasts approximately until the middle of the cycle.
What is the value of the basal temperature before menstruation will be in this case? The corresponding indicator should stop at 36.6 degrees. The difference may be 0.1 degree.
During critical days
Basal temperature before menstruation may be 36 degrees, but it is not the norm. We'll talk about deviations later. Let's look at typical life situations first.
During critical days the temperature is lowered. It will be below 36.6 and above 36.1 degrees. On the last day of menstruation, the average values are 36.4 degrees. This is normal.
Before X day
Ovulation is the period when the chances of getting pregnant are highest. And so girls often "catch" her. Tracking body temperature is one of the most accurate methods for determining ovulation.
Before ovulation (as well as menstruation), the indicators will be lower than usual by 0, 1-0, 2 degrees. A day or two before day X, they decrease and then increase.
Ovulation
Basal temperature before menstruation is important. She ismay indicate pregnancy, ovulation, or some medical condition.
Basal temperature before menstruation at 37.2-37 degrees is normal if ovulation is coming soon. The closer the day of release of the egg from the follicle, the higher the corresponding indicators will be.
Is it normal to rise to 37.5 degrees? Yes. This phenomenon is associated with an increase in progesterone. It raises body temperature. With its help, the further development of the fetus occurs with successful fertilization.
Luteal phase
What is the basal temperature before menstruation after the middle of the cycle? Namely, after ovulation?
The luteal phase is accompanied by an increased "temperature regime". During this period, the normal temperature is from 37 to 37.5 degrees Celsius. Lower maybe, higher no.
Accordingly, an increase in temperature is not always a sign of illness or a reason for panic. At least in mature women.
In a couple of days
And what is the basal temperature before menstruation a day or 3 days before the "incident"? It will not be possible to unequivocally answer such a question.
The thing is that the spread of indicators in this period is very wide. Normal is a gap of 36.8-37.2 degrees. Such values should not cause panic.
Difference between phases
In general, the studied component often depends solely on the body of a single person. And therefore it is impossible to say exactly when this or thatthe value is the deviation. You will have to carefully monitor your he alth so as not to make a mistake.
Basal body temperature in the day before menstruation is not measured. Physical activity distorts reality. Therefore, measurements are carried out only in the morning. And we have already got acquainted with the approximate temperatures.
It is important to pay attention to the difference between the phases of the menstrual cycle relative to the basal temperature. Before menstruation, it is increased, after them it decreases.
If you look closely at the BT chart, you will notice that the cycle is divided into 2 phases - before and after ovulation. The spread of indicators between them should be no more than 0.4 degrees. Otherwise, one should suspect violations of vital processes in the body.
Pregnancy
It's hard to believe, but the indicator we studied helps determine pregnancy. The main thing is to know how to do it.
Here are the phenomena that can be observed during successful fertilization of the egg:
- Temperatures will rise to 37 degrees (or higher) and stay at this value for 3 days longer than in the previous cycle.
- The BT chart has not 2 waves of temperature fluctuations, but 3.
- Basal temperature elevated for more than 3 weeks.
All these phenomena often indicate the development of pregnancy. If a girl observes them at home, you can do a test at home or go to a gynecologist.
Progesterone deficiency
Now a few words about what the basal temperature chart will look likebefore menstruation and after them in case of certain diseases.
For example, there is a progesterone deficiency in the body. Then the graph "jumps" down. The temperature rises slowly and stays elevated for too long. The second segment of the cycle is shortened to 10 days (instead of the average 14).
With progesterone deficiency at the very beginning of the cycle, there is a decrease (36 degrees and below), then the temperature slowly rises, but it does not reach normal levels.
Endometritis
Quite often, women experience endometritis. So called inflammation of the uterine mucosa. In this case, an increase in temperature is observed.
As a rule, the temperature value will fluctuate within the normal range. But in the first days of the new cycle, it rises to 37-37.2 degrees. It is this phenomenon that indicates the inflammatory process in the body. And not necessarily endometritis.
No ovulation
What if there is no ovulation? What then happens to the studied indicator?
This situation is well tracked on the BT schedule. The thing is that in the absence of ovulation, the temperature can be any. It is very difficult to build a graph, since the points line up randomly. No dynamics or principles of increase / decrease can be determined from the drawing. And break the "drawing" into 2 phases too.
Appendages and their inflammation
Sometimes it happens that a woman suffers from inflammation of the appendages and is unaware of it. The student will help clarify the situation.indicator.
Now we have found out the norms of temperature in a he althy woman. If there is inflammation in the body, the indicators increase. In our case, we will face a very high temperature after ovulation. It rises to 38 degrees or more. In the first half of the menstrual cycle, the indicators will be close to 37 degrees.
Influencing factors
It is worth paying attention to the fact that the basal temperature may vary depending on external factors. Their impact on the body is underestimated by some.
What phenomena can distort the data obtained? For example:
- stress;
- overwork;
- insomnia;
- drinking alcohol;
- presence of bad habits;
- transportation, flights;
- acclimatization;
- sexual intercourse 4-6 hours prior to data collection;
- taking hormone-containing drugs.
These are the most common occurrences. They can correct temperature fluctuations before menstruation in one case or another.
How to get results
Some people wonder what it takes to navigate BBT charts and data. There is only one really effective advice - it is to keep a schedule constantly.
You can navigate by basal temperature already after 2-3 cycles, the data for which are recorded on a special drawing. It is advisable to draw conclusions from the charts for the last six months.
How to measure temperature
How much is the basal temperature before menstruation? Answerthis question will no longer cause any trouble. Each girl will be able to understand whether everything is normal with her body on a given day of the menstrual cycle.
How to measure BBT? To do this, you can collect data:
- oral;
- rectally;
- vaginal method.
The most accurate BBT readings are collected in the anus. It is better to give preference to him.
In any case, the girl will need to act like this:
- Wake up and immediately take a measuring device.
- Keep the thermometer in your mouth for at least 5 minutes, in your vagina or rectum for 3 minutes.
- Record the received data by putting a mark on the BT chart.
That's it. It would seem that there is nothing difficult in this. But in fact, scheduling gives some trouble to the fairer sex.
Advice for women
Let's take a look at some helpful tips to get the most accurate body temperature readings.
They look like this:
- Measure the temperature only in the morning. Physical activity and fatigue greatly distort the real picture of what is happening in the body.
- Use the same instrument for measurements. If you need to replace the thermometer, it is recommended to make an appropriate mark on the temperature graph.
- Measure the temperature with only one of the proposed methods.
- Record all data about BT and record them on the appropriate graph. For example, with the help of special "calculators". They are on almost every women's forum.
- Collect data at the same time. As a rule, it is best to do this at 6-7 am or immediately after waking up.
That's it. As we have already said, it is necessary to measure body temperature without getting out of bed. Therefore, it is better to put the measuring device near the bed.
Conclusion
We have fully understood the issue under consideration. From now on, every girl will be able to build a BT schedule and understand when she ovulates. Diseases and inflammations can also be seen from the corresponding drawing.
As a rule, it is BT that helps women when planning a pregnancy. This indicator is of interest to girls with infertility. But it is not necessary to determine pregnancy, ovulation or inflammatory processes only by body temperature. As already mentioned, this indicator is easily distorted by external factors.
