After women enter puberty, the uterine wall is affected by the uterine and ovarian hormones, and regular uterine bleeding occurs, which is called menstruation. The regular changes in the uterine wall are called the physiological cycle, which is also the human reproductive cycle. The menstrual period is divided into many situations, with the due date of pregnancy being the most important. Let’s discuss what the missed menstruation means. The due date refers to the first day of a woman's last menstrual period. It is very important for women to remember their due date, because they can usually calculate symptoms and even important life events based on the due date. For example, if a woman is pregnant, she can calculate her due date based on the due date; she can also calculate her menstrual cycle based on the due date. When women experience irregular menstruation or abnormal uterine bleeding, when they go to the hospital, the doctor will usually ask when the due date is. Therefore, women should try to remember their due date when they have their period. A woman's menstrual period is generally about 28 days. If there is a problem with the menstrual cycle, it may be due to endocrine imbalance or other reasons. Therefore, women should try to remember their due date. The time interval between the first days of 2 menstrual periods. Most of them are within 28 to 30 days, and 3 days earlier or later is within the normal range. The length of the cycle varies from person to person, but every woman's menstrual cycle must have her own periodicity, otherwise it should be considered abnormal. The so-called menstruation is the first day of the last menstrual period before pregnancy. Generally, the pregnancy time is calculated from the first day of the expected date of delivery. It is recommended to start calculating from the first day of the expected date of delivery, about 45 days before going to the hospital for a color Doppler ultrasound to check whether the fetal sac has entered the uterine cavity to rule out the possibility of ectopic pregnancy. |
