What is the basal body temperature (1)? In the menstrual cycle, the basal body temperature before ovulation is usually low, and the normal body temperature before waking up in the morning (that is, the basal body temperature) is lower than 37 degrees, about 36.4 to 36.6 degrees. During ovulation, the body temperature dropped slightly, and after ovulation, the body temperature rose by an average of 0.5 degrees, which only lasted until before menstruation.
(2) The basal body temperature is generally 36.5℃ in follicular phase, and it is higher than 0.5℃ in luteal phase. Therefore, biphasic expression occurs, indicating ovulation. If the monophasic type has no late body temperature curve, it means that there is no ovulation, and the accuracy rate is 70%? 80%。
(3) The basal body temperature usually rises with ovulation, and in the first half of the menstrual cycle, the body temperature fluctuates below 36.6 degrees. After ovulation, it enters the second half of the menstrual cycle. Body temperature rises from the first half of the year, fluctuating between 36.6 degrees and 37 degrees. Rising body temperature means that a person has ovulated. After a high temperature period of about two weeks, the body temperature drops again and then enters the menstrual period.
(4) If the baby is pregnant, the basal body temperature will not drop, but it will continue to be in a high temperature state, and the body temperature will continue to rise after pregnancy due to the increase in the amount of hormones secreted by the ovaries.
How to Measure Basal Body Temperature on Ovulation Day It is meaningless to simply measure the temperature on the day of ovulation. It is suggested to monitor the basal body temperature. The monitoring of basal body temperature is to wake up in the morning without talking or moving, put the thermometer under your arm for 5 minutes, then read the temperature on the thermometer and write it down on paper until the next menstruation. According to the change of basal body temperature, you can know whether there is ovulation.
The basal body temperature is measured from the first 1 day of menstruation until the next menstruation.
If in the first half of menstruation, when the basal body temperature is measured, there is a relatively low temperature, but in the second half of menstruation, the basal body temperature rises, which is around 37℃ and the high temperature lasts for more than 12 days, indicating ovulation. Most of them will have 1 day in the middle period of menstruation to minimize their basal body temperature, which is basically the day of ovulation.
