The head of the fetus at this stage is already very large, with a circumfer circumferance equivalent to the chest ring when the baby is born. You'll also see a pretty chubby baby with flesh on your elbows, wrists, knees, as well as small marks on your neck or shoulders.

The mother's labor day is approaching, exactly the fetus will be born within 3 weeks, but the baby can still be born earlier on any day from this time.

Although the fetus now looks like a normal newborn, in reality the baby is not quite ready to adapt to the outside world. The fetal lungs, although developed, are incomplete and require more time. Specifically, in the next two weeks, the baby's lungs and brain are completely mature. Therefore, although the date of birth is near, doctors will not identify as a full-month baby until the 39th week of pregnancy.
