How many days will ovulation occur during ovulation?

Generally speaking, a woman’s menstrual cycle lasts for 28 days, but in reality, some women may have it a few days earlier or later. Therefore, for people with regular menstrual cycles, ovulation can be determined by measuring basal body temperature and observing other changes during the menstrual cycle.

Basal body temperature refers to the body temperature measured when a woman wakes up every morning. Generally speaking, a woman’s body temperature will rise by 0.3-0.5 degrees Celsius during ovulation, which is called the body temperature rising period. During this period, a woman's egg may be released and, if fertilized, pregnancy may result.

In addition to measuring basal body temperature, observing other changes during the menstrual cycle can also determine ovulation. For example, if women have more sex and discharge early in their menstrual cycle, that could mean they will release an egg during ovulation.
