At the end of the eighth week after fertilization (week 10 of pregnancy), the embryo is considered a fetus. During this stage, the structures that have already been formed grow and develop. The following are the characteristics of each week of pregnancy: At 12 weeks of pregnancy, the fetus fills the entire uterus. About 14 weeks, sex can be identified. Around 16 to 20 weeks, the pregnant woman can feel the movement of the fetus. Around 24 weeks, the fetus has a chance of surviving outside the womb. At week 25, the fetus is placed in the position for delivery. From week 37 to 42, labor may occur
The lungs continue to mature until near the time of birth and the brain accumulates new cells during pregnancy and until the first year of life after birth.
