In the female menstrual cycle, the 14th day is the ovulation period, which is a very important day in the female reproductive cycle. During ovulation, a woman's egg is released from the ovary and travels through the fallopian tube into the uterus, where it is ready to combine with sperm to form a fertilized egg.

Below, we'll introduce several common calculation methods to help women calculate their ovulation days.

1. Observe secretions

Observing a woman's discharge can help women calculate when they are ovulating. During ovulation, a woman's vaginal discharge will become thinner, darker, clear or white. If women notice these changes in their discharge, they are ovulating.

2. Measure body temperature

Measuring body temperature is also a way to calculate when a woman is ovulating. Women can take their temperature every morning when they wake up and record it on a form. During a woman's ovulation period, her body temperature will rise by about 0.3-0.5 degrees Celsius.

3. Use a thermometer

Using a thermometer can help women accurately measure their body temperature.
