After pregnancy, menstruation stops and can only resume six months or a year after giving birth. Because after pregnancy, the levels of estrogen and progesterone in the body increase, so menstruation does not occur. It seems that there is still a relationship between pregnancy and menstruation. Is there a relationship between pregnancy and menstrual cycle?
The calculation of specific pregnancy days, including the estimated due date, usually starts from the first day of the last menstrual period. And the length of the menstrual cycle is also related to pregnancy. The extension or shortening of the menstrual cycle may be a gynecological disease, which can also affect pregnancy.
Whether a woman can conceive normally is related to many factors, including male and female factors. The female factor accounts for a larger proportion, whether hormone secretion is normal, ovulation is normal, whether the uterus is deformed, and whether the fallopian tubes are normal can all affect normal pregnancy. The male factor is mainly related to sperm issues.
The menstrual cycle and amount of menstrual bleeding in women are related to changes in physical condition, hormone levels in the body, and external environmental influences. If the menstrual cycle is normal, it is between 28 and 30 days. It is normal to have it within 7 days in advance or 7 days later. The duration of a menstrual cycle is 3-7 days. If the duration is less than 3 days or longer than 7 days, it is considered as prolonged or insufficient menstrual flow.
