Medical indications

What is the essence of measuring basal temperature? Gynecologists say that its height is determined by the phase of the woman's cycle. That is, the temperature before menstruation will vary depending on which day you measure it. Physiologically, this is quite understandable: the sex hormone progesterone in a certain way affects the thermoregulation center, which is located in the hypothalamus. Since the concentration of this hormone in the body changes on different days of the female cycle, according to it, the basal temperature will be characterized by different indicators.

Diseases and conditions

So, who might need to take their temperature before their period? First of all, women who have long and unsuccessfully tried to conceive a child. Such measurements help determine the most favorable days for conception. Secondly, the measurement of basal temperature is successfully used as a method of contraception. Thirdly, its fluctuations make it possible to detect the presence of hormonal disorders and inflammatory processes occurring in the pelvic organs. Finally, it is often measured during so-called "delays".

What should be the norm?

Normal temperature before menstruation in a completely he althy woman goes through several stages. During the first phase (doctors refer to it as "follicular"), the indicators, as a rule, do not exceed 37 degrees. On average, it fluctuates between 36.4 and 36.7. Just before the onset of ovulation, the temperature drops slightly, and then jumps sharply by 0.5 degrees. The thermometer will hold this mark throughout the second, or as it is called the luteal, phase of the cycle. The temperature before menstruation becomes slightly lower. During critical days, it is usually around 37 degrees. After making simple calculations, we can summarize that the basal temperature in the luteal phase of a woman whose he alth is in perfect order is 37.2-37.4 degrees.

Indicators

However, whatever the subfebrile temperature before menstruation, you should pay attention to the difference in performance between the first and second phases. Normally, it will be about 0.4 degrees.

Possible causes of abnormalities

All deviations from the norm indicated above can be due to a number of reasons. Among the most common, gynecologists call diseases such as endometritis and inflammation of the appendages. In addition, the reason may be a lack of progesterone in the body. In some cases, changes in temperature indicate the onset of pregnancy. The last option needs to be said in more detail.

Pregnancy

Basal and rectal temperatures before menstruation indicate a woman's pregnancy only when their indicators before the onset of menstruation do not decline and exceed 37 degrees. It must be emphasized that if, instead of the usual heavy periods, you find scanty bleeding on your underwear, but the basal temperature is still above 37 degrees, you need to see a doctor as soon as possible: there is a threat of miscarriage.
