A temperature of 36.9 is in the early stages of pregnancy.

The symptoms of pregnancy are varied. A comprehensive understanding of the basic knowledge of pregnancy symptoms can help us detect whether a woman is pregnant earlier. Some pregnant women are careless and unaware of their pregnancy, which causes some accidents to affect their pregnancy. Is a body temperature of 36.9 in the early stages of pregnancy?

1. Is a body temperature of 36.9 a sign of pregnancy?

A woman's body temperature will rise to a certain extent after pregnancy, but the rise in body temperature is between 36.9℃-37.2℃, which is a normal reflection. If this high temperature period lasts for more than 21 days and there are no other abnormal reactions, no menstrual cramps, or even early pregnancy reactions, it can generally be considered a sign of pregnancy. If the body temperature is high and low, it should be taken seriously, especially for patients with recurrent miscarriage, who should take timely and effective measures.

The temperature changes in the early stages of pregnancy are due to the fact that estrogen has a warming effect, which can increase the body temperature by 0.3-0.4 degrees above normal. For example, women are treated with estrogen during and after menstruation, and their body temperature is 36.5 degrees Celsius. It is lowest during ovulation. After ovulation and pregnancy, estrogen is used to treat the body temperature, and the body temperature rises by 0.3-0.4 degrees Celsius after pregnancy. The body temperature will return to normal when the next menstruation comes or the day before it.

After a woman becomes pregnant, her corpus luteum rises. Generally, the basic body temperature during the follicular phase is 36.5°C. The temperature rises by more than 0.5°C during the follicular phase, thus forming a biphasic phenomenon, indicating ovulation. If the monophasic electrical pattern does not have a temperature curve that rises in the middle and late stages, it indicates that ovulation has not occurred, and the success rate is 70% to 80%. If you have any questions, you can consult a specialist.

2. Accurate measurement of body temperature in early pregnancy

1. Changes and records of body temperature in early pregnancy

Compared with our normal ovulation body temperature, the temperature changes in early pregnancy will be more significant. In order to accurately measure the human body temperature during this period, we recommend that you learn the following methods. The body temperature measured after waking up in the morning and before doing any activities is the body's temperature under the most basic activities. The body temperature is measured at this moment and the measured results are recorded on the basal body temperature table. In addition, the menstrual time and frequency of sexual life should be recorded.

If there are other symptoms, it may be particularly indicated, such as fever, lower abdominal pain during the cycle, vaginal spotting, etc. The BBT of women with normal physiological cycles is biphasic, that is, in the second half of the menstrual cycle, due to the effect of luteinizing hormone, the BBT increases by 0.3-0.4℃ compared with the first half of the cycle.

2. Clinical medical use of body temperature in early pregnancy

What role does regular and accurate measurement of the body temperature of pregnant women in the early stages of pregnancy have in clinical symptom treatment? In fact, changes in body temperature in the early stages of pregnancy can reflect the regular activities of the uterus and ovaries. Generally, accurate measurement of 2-3 cycles can infer the regularity of ovulation and distinguish whether ovulation has occurred. The ovulation time can be predicted based on the ovulation period, that is, the day with the lowest body temperature in the middle and late menstrual period or the day before the body temperature rises.

Women who want to get pregnant successfully or take immediate contraceptive measures should monitor their body temperature at any time. It is important to know that the two days before and after the body temperature drops to at least the safe period for pregnancy. The period before is the relatively safe period, and the period after is the absolutely safe period. If your high temperature lasts for more than 20 days, you can be diagnosed with early pregnancy. Many infertile women can also feel changes in body temperature. The high temperature period is shorter than 10 days, and the difference between high and low temperatures is less than 0.3℃, which should be considered as luteal insufficiency.
