If a woman monitors her basal temperature, she can find out how well her reproductive system functions. Over time, she will learn to determine the time of onset of ovulation and menstruation, she will be able to suspect pregnancy and inflammation.
At first glance, the method seems uncomfortable and suspicious. However, a woman, as a rule, very quickly gets used to measure the temperature every morning . Conducting research for several months and seeing that the method works, begins to trust him.
So, let's see how it works. The menstrual cycle is divided into two periods, their ovulation separates. Before her, the level of estrogen is high, providing follicle growth. These hormones lower basal temperature.
After ovulation, progesterone is secreted by the corpus luteum. This hormone raises the temperature. When its level decreases, menstruation begins. Therefore, the temperature is low in the first phase and high in the second. The difference between their average values should be more than 0.4 degrees.
In the second phase, the basal temperature is usually 37 or higher, and in the first it is kept below this mark. However, other indicators do not always talk about pathology, but may be a variant of the norm.
Basal temperature 37 and above should be kept for two weeks. The length of this period can vary by two days. If it is less than 10 days and the temperature level is below normal, then corpus luteum failure is possible . In such a situation, the onset of pregnancy becomes problematic.
In this case, the progesterone level is checked and progestogens are prescribed, mainly Dufaston. If pregnancy has occurred against his background, then his admission should be continued up to 20 weeks to avoid miscarriage.
A basal temperature of 37.2 degrees is usually the highest in the second phase. Too high values may indicate inflammation of the appendages. Although there are cases when it rose to 38, and this was a variant of the norm. It is also important to take into account the general temperature of the body, which rises with the flu and other diseases.
A basal temperature of 37 or slightly lower lasts several days before menstruation, usually 3. This is due to a decrease in progesterone levels.
Perhaps a one-day decrease in temperature 7-10 days after ovulation. This phenomenon is called implantation retardation. At this point, the embryo invades the endometrium. The decrease in temperature is due to the fact that there is a jump in the level of estrogen, and on the other hand, progesterone production is already reduced during this period.
The basal temperature is 37.4, the absence of menstruation and the duration of more than 18 days of the second phase may indicate a pregnancy. At this level, it should stay for the first 4 months. Then the measurement becomes uninformative.
The temperature may be lower, but should exceed 37. If its values are lower, then you can suspect a threat of miscarriage due to lack of progesterone. In this case, an analysis is given to determine its level. When confirming concerns, gestagens are prescribed.
If the basal temperature drops before menstruation, and during them rises, this may be evidence of inflammation of the uterine mucosa. Normally, during the period of menstruation, the temperature should gradually decrease to the minimum values of the first phase.
If the basal temperature of 37 with slight fluctuations lasts throughout the cycle, this may mean that there is an increased amount of prolactin. It blocks the release of LH, FSH and ovulation does not occur. Pregnancy in such a cycle is not possible.
If the temperature is kept high before and during unusual periods, and after them it drops sharply, then there may have been a miscarriage in the early stages. However, only the gynecologist can decrypt the obtained data.
So, the basal temperature at the level of 37 degrees and above should be in the second phase and in the first months of pregnancy. During menstruation and before ovulation, such values are a pathology.
