The three most unsafe "contraceptive periods"
Safe period contraception
Women of childbearing age are most likely to conceive within 2 to 3 days after the ovulation period each month. There are more than 20 days in a month that are difficult to conceive, called "safety period." However, the "safe period" is not safe.
Although women's ovulation time is mostly in the mid-term, but due to external environment, temperature, mood, health and other factors, can make ovulation time ahead or postponed. Some women may also experience "additional ovulation" when they are stimulated by sexual activity, and they develop reluctant "fruits." To this end, women of childbearing age still choose reliable long-term contraceptive measures as well.
Menopause contraception
Menopausal women think that their menstruation is scarce, close to menopause, will no longer have the chance of pregnancy, thus giving up contraception. However, according to statistical data from obstetrics and gynecology in some hospitals, the highest flow rates among people in all age groups are from 40 to 45 years old, followed by the 20 to 24 year old group.
The reason is that women go to menopause, and although ovarian function declines, estrogen and progesterone secretion decrease, but the ovary may still ovulate, still pregnant. Relevant data show that due to unhealthy egg aging, menopausal women are pregnant, the incidence of hydatidiform mole 4 to 7 times higher than women of childbearing age, and there are many malignant transformation (metacarpal malignant transformation or choriocarcinoma). In this regard, menopausal women should also insist on contraception until 1 to 2 years after menopause.
Contraception during lactation
The human "endocrine king" - the pituitary gland is controlled by the "top boss" hypothalamus. When the baby sucks the nipple, it can reflexively inhibit the hypothalamus and inhibit ovarian ovulation. If the baby sucks, the nipples decrease, or the mother is affected by environmental changes, climate changes, mood changes, and sexual life, it is likely to affect ovarian ovulation through the cerebral cortex.
Because of ovulation first, menstruation is behind, some women may be pregnant before the menstruation of the future, commonly known as "dark pregnant." According to the survey, 5% to 10% of women are inexplicably pregnant during lactation. Postpartum contraception is generally appropriate for the use of condoms and upper birth control rings, and it is not advisable to take birth control pills so as not to affect nursing babies.
