Ovulation refers to the time during a woman’s menstrual cycle when eggs are released from the ovaries and enter the fallopian tubes. Generally speaking, women start to produce eggs on the 14th day of the menstrual cycle, and the eggs can only survive for 12-24 hours, so the ovulation period is between the 14th and 21st days of the cycle.

In addition to changes in reproductive organs, women may also feel some discomfort during ovulation, such as nausea, headache, breast swelling and pain, etc. These symptoms usually appear within a few hours after the egg is released, but may occur for longer.

Although ovulation may be uncomfortable, it is still an important time for women to become pregnant. If a woman fails to fertilize during this period, she may try again during her next menstrual cycle. Therefore, knowing how to predict ovulation and taking appropriate measures is very important to ensure a successful pregnancy.

A woman's menstrual cycle and fertility are affected by many factors, such as age, health, diet and exercise. Therefore, if you suspect you may be pregnant, it is best to consult a doctor or professional counselor to determine the best time and method to get pregnant.
