Expectant parents are very happy about the arrival of their baby, especially novice parents who are immersed in the joy of being parents and eager to know how many days their baby is. Calculating the due date allows for scheduling work and personal time, so that there won't be so much fuss and confusion. So, how to calculate the time of pregnancy?
According to medical regulations, the due date is calculated from the first day of the last menstrual period, and the entire pregnancy period is 280 days, with 10 pregnancy months (each pregnancy month is 28 days, or 40 weeks). In general, the most commonly used method for calculating the due date is the last menstrual period calculation method, which means subtracting 3 (adding 9 if insufficient) from the month of the last menstrual period or adding 9 directly to the month. Adding 7 days to the number of days is the due date.
If you want to calculate the pregnancy cycle, if you feel that the menstrual algorithm is not reliable or have forgotten the last time you had your period, it is recommended to choose the time of fetal movement to calculate the pregnancy cycle. Generally, fetal movement occurs around 18-20 weeks of pregnancy, but this method is already in mid pregnancy and is relatively late.
It is recommended that pregnant women go to regular hospitals for timely diagnosis of pregnancy, clarify the size and development of the fetus, determine whether the embryo implantation site is in the uterus, in order to screen for the possibility of abnormal pregnancy and ensure the health and safety of both the pregnant woman and the fetus. In addition, during pregnancy, timely and reasonable prenatal check ups should be arranged according to one's own situation to clarify the growth and development of the fetus at each stage, ensuring the health and safety of both the pregnant woman and the baby.
