Ovulation refers to a period of time in a woman's menstrual cycle, usually around 14 days between menstruation. For couples who want to have children, it is very important to understand the ovulation period, because women will release eggs during ovulation, which is one of the necessary conditions for the pregnancy of a fetus. However, for those who do not plan to have children, knowing the ovulation period is not necessary. So, how many days before ovulation? We will introduce it to you below.

So, how to calculate ovulation? It is calculated by measuring basal body temperature. Basal body temperature refers to the level at which a woman's body temperature rises to about 37 degrees Celsius within a certain period of time (usually when she wakes up in the morning). Women can monitor their menstrual cycle and determine ovulation by recording their basal body temperature.

So, is the basal body temperature measurement method reliable? The answer is yes. A woman's basal body temperature is affected by hormonal levels and therefore may be subject to error. However, by recording basal body temperature and using it in conjunction with other measurement methods, such as a calendar and observing symptoms, women can better understand their menstrual cycle and health.

So, how many days before ovulation? Generally speaking, symptoms that women experience before ovulation include increased sexual desire, breast swelling, headaches, and fatigue. These symptoms usually appear 1-2 days before ovulation. However, these symptoms do not necessarily mean that a woman is in danger before ovulation.
