The process of ovulation in women, also referred to as ovulation, usually lasts for about 10 days. For women who usually have a regular menstrual cycle, the day of ovulation is usually about 14 days before the next menstrual period, and the process of adding the day of ovulation to the 5 days before the day of ovulation, and then adding the 4 days after the day of ovulation is known as the process of ovulation, which in most cases lasts about 10 days. However, due to different hormone levels in each woman’s body, environmental factors, etc., may affect the length of time ovulation lasts. If a woman has fertility requirements, it is recommended to have intercourse during the ovulation period for a relatively higher chance of conception. However, since the precise period of ovulation is relatively short and easy to miss, it is recommended to monitor ovulation through ultrasound.
