The ovulation period refers to the time when a woman's eggs are released from the ovaries to the fallopian tubes. It is also an important period for women to have children. Generally speaking, ovulation in women occurs between the 14th and 20th days of the menstrual cycle. However, the specific date may be affected by various factors, such as climate, mood, diet, etc.

Here's how to measure basal body temperature:

1. Measurement time: Measure your temperature at the same time every day, such as when you wake up in the morning.

2. Measuring tool: Use a thermometer, place the thermometer under your tongue, and measure your oral or anal temperature.

3. Record data: Record the measured body temperature data in the body temperature record book and draw the basal body temperature curve.

By measuring basal body temperature, a woman's ovulation period can be predicted. Generally speaking, when the body temperature rises above 18 degrees, it means that a woman’s ovulation period has passed. However, this method is not always accurate because a woman's menstrual cycle is affected by many factors.

In addition to measuring basal body temperature, there are other ways to predict a woman's ovulation period. For example, a woman's menstrual cycle can be observed to calculate a woman's safe period; or a woman's ovulation period can be predicted by checking whether the woman's cervix is ​​open.

Women's ovulation period is very important for fertility, so we should pay close attention to our basal body temperature curve and choose a fertility method that suits us according to our own situation.
