What is the basal body temperature graph?
The basal body temperature curve is a method commonly used by women when planning their fertility. By recording their daily basal body temperature and drawing a body temperature curve, they can infer their ovulation period and safe period. Basal body temperature refers to a woman\’s resting body temperature. It is usually measured after getting up in the morning and before engaging in heavy activities or eating. Because a woman\’s body temperature will rise to a certain extent after ovulation, only the basal body temperature measured at the same time has reference value.
What are the ovulation signals in the body temperature curve chart?
1. Changes in body temperature between two consecutive times: When a woman’s body enters the ovulation period, her body temperature will rise to a certain extent. Therefore, if you find during the process of measuring your basal body temperature that your body temperature has been relatively low in the past few days, but there is a sudden and obvious increase in body temperature, it is likely to be a signal of ovulation.
2. The shape of the body temperature curve: If ovulation is successfully completed, the body temperature curve will usually show a triangular shape, that is, it first decreases, then increases, and then returns to the basic level. If the body temperature curve drops or rises midway, something may be abnormal.
3. Continuous rise in body temperature: A few days after ovulation, a woman\’s body temperature usually rises to a certain extent, which is also an ovulation signal in the basal body temperature curve. If the body temperature can continue to rise for more than three days, it means ovulation has been completed.
How to draw the basal body temperature curve correctly?
To draw an accurate basal body temperature curve, you first need to do the following:
1. Measure body temperature: Use the same thermometer at the same time and place every day to record the actual basal body temperature. In order to avoid inaccurate body temperature caused by overexertion, it is recommended to continue to lie in bed after getting up in the morning and use an ear or rectal thermometer to measure.
2. Record data: Mark the measured data on the thermometer to facilitate future analysis and calculation. You should also record information such as the length of your menstrual cycle, the start and end of menstruation, and so on.
3. Analyze data: Draw the data into a curve graph using a computer or manually, and conduct analysis and judgment. Accurate judgment requires the help of professional ovulation test strips, B-ultrasound, blood hormone tests and other auxiliary means.
What is the safety period?
The safe period is the time in the menstrual cycle when it is extremely unlikely or impossible for a woman to become pregnant. Usually the 28-day cycle of each month is divided into 14 days, and the time is divided into two stages: 14 days before menstruation and 14 days after menstruation. During this period, women basically don’t have to worry about getting pregnant. Of course, every woman’s physical condition and endocrine level are different. The safe period is only a rough estimation method and cannot be completely relied on. If you want to have children or prevent pregnancy, it is recommended to use multiple methods, such as basal body temperature measurement, birth control pills, condoms, etc. to coordinate with each other and improve the effect.
Summary
The basal body temperature curve is a method of inferring the ovulation period and safe period by measuring basal body temperature.The rise in body temperature after ovulation, the triangular shape of the body temperature curve, and the continued rise in body temperature are all signals of ovulation. Drawing a basal body temperature curve requires accurate measurement, data recording, analysis and judgment. The safe period is a way of contraception for women, but it should be noted that each woman’s physical condition is different and cannot be completely relied on. It is safer and more reliable to coordinate the effects of contraception or fertility by using multiple measures.
