Women of childbearing age are most likely to conceive within 2-3 days after ovulation each month. More than 20 days in a month are difficult to conceive, which is called the "Calendar-based contraceptive methods". The "Calendar-based contraceptive methods" is not safe. Although women's ovulation time is mostly in the middle of menstruation, it can be advanced or delayed due to factors such as external environment, temperature, emotions, and health status. Some women may experience "extra ovulation" and bear unwilling "fruits" when stimulated by sexual activity. Therefore, it is best for women of childbearing age to choose reliable long-term contraceptive measures.

Breastfeeding contraception is the king of human endocrine system - the pituitary gland is controlled by the top boss, the hypothalamus. When a baby sucks nipple, it can reflect and suppress the hypothalamus and ovarian ovulation. The baby's nipple suction is reduced. When the puerpera are affected by environmental changes, climate changes, emotional changes, and sexual life, the Cerebral cortex is highly likely to affect ovarian ovulation.

Ovulation occurs first, and after menstruation, some women may become pregnant before menstruation, commonly known as dark pregnancy. A survey shows that 5% to 10% of women become incredibly pregnant during breastfeeding. It is generally best to use condoms and contraceptive rings for postpartum contraception, and do not take birth control pills to avoid affecting breastfeeding infants.

Menopausal contraception: Women who are in menopause believe that their menstrual cycle is rare, approaching menopause, and there is no chance of pregnancy, so they give up contraceptive measures. However, according to statistical data from some hospitals' obstetrics and gynecology departments, the highest abortion rate among age groups is 40-45 years old, followed by 20-24 years old.

The reason for this is that when women reach menopause, their ovarian function declines, and their secretion of estrogen and pregnancy hormones decreases. However, the ovaries have the possibility of ovulation and pregnancy. Related data shows that due to unhealthy aging of eggs, the incidence of raisins in menopausal women who become pregnant is 4-7 times higher than that of women of reproductive age, and there are more malignant changes (malignant changes in raisins or velvet cancer). On the contrary, menopausal women should also adhere to contraception until 1-2 years after menopause.
