How Do I Choose the Best Electronic Thermometer?

Basal body temperature curve: It is the focus of many women before and during pregnancy. The change of basal body temperature is also one of the methods to determine whether you are pregnant, but many women are often not familiar with the basal body temperature curve and do not know how Measure your own basal body temperature accurately, not to judge various basal body temperatures. The horizontal axis represents the date, menstrual cycle day, and same-room day, and each cell is 1 day. Starting from the first day of menstrual tide, draw the basal body temperature measured every day with dots in the grid of the corresponding temperature record sheet, until the day before the next menstrual tide, and finally use a straight line for each dot. Connected in order, it becomes the basal body temperature curve chart of 1 menstrual cycle. In case of cold, fever, diarrhea, insomnia, drinking, use of electric blankets, etc., it is easy to affect the basal body temperature, which should be explained in the notes below the basal body temperature curve.

Basal body temperature curve

1. Prepare one

   The importance of basal body temperature to women is self-evident. More and more women are beginning to pay attention to their basal body temperature. Although many people measure the basal body temperature, they do not have much reference value. The reason is that Improper selection of thermometers will cause data distortion. Therefore, to accurately measure basal body temperature, you need to select and purchase specialized

   The basal body temperature of normal women of childbearing age, like the menstrual cycle, shows periodic changes. This body temperature change is related to ovulation.

   Women's menstrual cycle begins with the first day of menstruation. The length of the cycle varies from person to person, ranging from about 21 to 35 days, with an average of about 28 days. It is divided by ovulation days and divided into pre-ovulation The follicular phase, and the luteal phase after ovulation. The follicular phase is not necessarily long, but the luteal phase is fixed at about 14 days and up to two days. The next day after ovulation, the corpus luteum is formed, and the secretion of progesterone will increase the body temperature by about 0.6 degrees Celsius, which will cause the body temperature to show a two-phase change. The high temperature period lasts about 12-16 days (average 14 days).

   1. If there is no pregnancy, the corpus luteum atrophy stops secreting progesterone, the body temperature drops, returns to the basic line, and menstrual cramps.

   2. If you are pregnant, because the corpus luteum is supported by embryonic chorionic gonadotropin (hCG), it turns into a gestational corpus luteum, continues to secrete progesterone, and the body temperature continues to be high.

   3. If the ovaries are not functioning properly and there is no ovulation or corpus luteum formation, the body temperature will remain low.

   Determine if ovulation

   general

   1. Typical bidirectional body temperature: After ovulation, the corpus luteum secretes progesterone, and the body temperature rapidly rises by 0.3-0.5 degrees, and it continues to drop until the next menstrual period ;

   2. Biphasic body temperature with abnormal corpus luteum function:

   (1) Slow temperature rise

   Basal body temperature rises slowly

   (2) Insufficient increase in body temperature

   Insufficient increase in basal body temperature

   (3) Basal body temperature in the luteal phase is less than 12 days

   Luteal deficiency and high temperature for less than 12 days

   (4) After menstruation, the body temperature continues to be relatively high

   Body temperature remains high after menstruation

   3. Single-phase body temperature without ovulation menstrual cycle, lack of progesterone, although body temperature fluctuates, but there is no continuous temperature rise.

   4. The basal body temperature curve chart of pregnancy has been persistently high. Generally speaking, high temperature lasting more than 16 days is a sign of pregnancy.

   5. The basal body temperature curve of the suspected early abortion, which continues to cool down for a period of time. Generally, it is a sign of early abortion. If you find such a basal body temperature curve after pregnancy, you should go to the hospital as soon as possible to find out the cause.
