What is basal body temperature?
Basal body temperature refers to the body temperature measured under the armpit or mouth after waking up in the morning when sleeping, eating, exercising, etc. remain unchanged. Generally, a woman\’s basal body temperature changes during the menstrual cycle. It rises before ovulation, remains high after ovulation, continues to rise if conception occurs, and falls before menstruation if pregnancy does not occur.
How to measure basal body temperature?
1. Measurement time: After waking up every morning, do not get up first, maintain a half-lying and half-sitting posture, and then measure at the same time, method and location.
2. Measurement site: The two commonly used sites are the armpit and oral cavity. You can choose according to your personal habits. When measuring under the armpit, insert the thermometer into the armpit so that the thermometer is close to the skin. When measuring in the mouth, place the thermometer under the base of the tongue, close your mouth and do not open your mouth to breathe.
3. Measurement method: Use an ordinary digital thermometer. The measurement error of electronic thermometers is small. It is best to use a thermometer with a temperature of 0.1°C. Be sure to sterilize the thermometer before use and clean and disinfect it promptly after measurement.
How to use basal body temperature to predict ovulation?
Basal body temperature can reflect the period of ovulation, because the body temperature rises when the egg is released from the body. To correctly use basal body temperature to predict ovulation, you need to record your daily body temperature and draw a basal body temperature chart. In the basal body temperature chart, there is an obvious \”V\” or \”∧\”-shaped change in body temperature before and after ovulation, that is, the body temperature before ovulation is low and stable, and the body temperature after ovulation continues to rise.
How to analyze basal body temperature chart?
1. Endometrial phase: The first to fifth days of menstruation are the endometrial phase, when the basal body temperature is relatively stable and low.
2. Growth phase: The 6th to 15th day of menstruation is the growth phase. Follicles continue to grow, secrete estrogen, and the basal body temperature gradually rises.
3. Ovulation period: 2 days before and after ovulation (the day when the basal body temperature drops and suddenly rises and the 2 days after) is the ovulation period. The basal body temperature continues to rise and stabilizes at a high level.
4. Luteal phase: The luteal phase begins on the second day after ovulation and the day before menstruation. Due to the increased secretion of estrogen and progesterone, the basal body temperature will continue to remain at a high level. If pregnancy occurs, the basal body temperature will continue to rise. , if there is no conception, the basal body temperature will decrease before menstruation.
Summary
The basal body temperature method is a simple and convenient method to measure ovulation, but it requires time and patience. It is very important to correctly measure and record basal body temperature and analyze changes in basal body temperature charts. At the same time, it should also be noted that the basal body temperature method is not 100% accurate, but it only provides a more reasonable method of estimation. If necessary, it is recommended to conduct a comprehensive analysis in conjunction with other ovulation detection methods.
