Pregnancy is a complex process with many factors affecting its occurrence. One of the important factors is a woman's menstrual cycle and ovulation. The menstrual cycle usually refers to the number of days in a woman's month, and the ovulation period refers to the time in the menstrual cycle when a woman's egg is released.

However, pregnancy is more than just the union of eggs and sperm during a woman's menstrual cycle. Pregnancy also requires the support of many other factors, including the female's uterine environment, sperm quality and quantity, male sperm motility, and so on.

Therefore, to get pregnant, women need to maintain a regular menstrual cycle and ensure that ML is performed during the woman's ovulation period. At the same time, men also need to ensure the quality and quantity of sperm to ensure that women’s eggs can combine with sperm and form fertilized eggs.

If women want to become pregnant, it is best to consult a doctor or professional counselor to ensure they are undertaking ML at the correct time and receive the necessary help and advice.
