There is no saying how many weeks to give birth to a child as the best period, 39-40 weeks of pregnancy to give birth to a child is better. Fetuses delivered after 37 weeks to 42 weeks of pregnancy are considered full-term babies. If there are no special circumstances at this stage, try to wait until 39-40 weeks of pregnancy to have a baby, as the development of the fetus’s lungs, liver, and brain are more mature at this stage, and the ability of the fetus to survive after birth is better, and the chances of neonatal complications are lower. There are abnormalities in late pregnancy, such as fetal intrauterine distress, meconium contamination, placental abruption, and in urgent cases it is not possible to wait until the best time to give birth to a child, and timely termination of pregnancy should be dealt with according to the condition of the fetus and the pregnant woman. After pregnancy, women should project the time of the expected date of labor, in the expected date of delivery delayed or 2 weeks ahead of the normal, late pregnancy to observe the aura of labor symptoms, such as redness, the sense of descent of the fetus, regular uterine contractions, be ready to wait for the birth of the baby. Pay more attention to rest in late pregnancy and do a good job of pregnancy checkups, abnormalities in time to deal with.
