Ovulation refers to the time during a woman's menstrual cycle when eggs are released from the ovaries to the fallopian tubes. It usually refers to about 14 days before a woman's next menstrual period. The exact time of ovulation may vary for women of different ages.

For middle-aged women, the ovulation period is usually about 12 days before the next menstrual period. The specific time may vary depending on individual differences. This is because the menstrual cycle of middle-aged women is relatively long, and the time for egg discharge is also relatively long.

For older women, ovulation may occur earlier or later, and the specific time may vary depending on individual differences. This is because the menstrual cycle of older women is relatively short, and the time for egg discharge is also relatively short or the discharge is not smooth due to other reasons.

In general, the exact time of ovulation may vary for women of different ages. If you want to know when you are ovulating, it is recommended that you consult a doctor or calendarist. At the same time, it should also be noted that ovulation does not necessarily mean pregnancy. Only when sperm and egg meet can pregnancy occur.
