How to calculate the pregnancy month?

Some pregnant women should pay attention to their physical health and safety during pregnancy, especially the problem of calculating the body's cycle to avoid affecting the safety of the fetus and their own physical health. In particular, the calculation of the pregnancy month of pregnant women can accurately calculate the time of the baby's birth. So how to calculate the pregnancy month? Well, let me introduce it to you below.

Generally speaking, the gender of the fetus can be determined through B-ultrasound examination after 4 months of pregnancy. However, the country currently does not allow hospitals to identify the sex of the fetus, so pregnant women are advised to have regular prenatal checkups to ensure that the fetus is developing healthily. In addition, pregnant women should pay attention to rest, eat more rich and diverse foods, and appropriately supplement calcium, iron and other vitamins.

The correct calculation should be - pregnancy begins when the sperm and egg combine and begin to implant. Counting from this time, adding 266 days is a more accurate expected date of delivery. However, since most people cannot determine the day of fertilization, and the day of intercourse is not necessarily the day of fertilization, the former calculation method is more convenient. Although these 280 days include days when pregnancy has not yet occurred, these are all normal. The pregnancy time from June 6th to now is 132 days, about 19 weeks. You can do a fetal anomaly screening. When calculating the expected date of delivery, the most commonly used and common calculation method is used. That is, calculate backwards based on 280 days (40 weeks of gestation), add 9 (or subtract 3) to the month of the day of the last menstrual period, and then add 7 to the date.

Based on your situation, your wife's last menstrual period was on June 6th, so 6 minus 3 equals 3, and 6 plus 7 equals 13, so the expected date of delivery is March 13th, 2010. This reverse calculation is based on a 28-day menstrual cycle and must therefore be modified according to the length of the individual's menstrual cycle.

The above is my opinion on this issue. If you don’t know how to calculate the months of pregnancy, you should pay attention to taking scientific methods to calculate it in time for the health of the pregnant woman and avoid problems caused by incorrect calculation time.
