By the 12th week of pregnancy, the fetus' body length can reach 6.5 cm, and the baby has begun to show human shape. The rate at which the baby is developing is becoming more astonishing this week.

At 12 weeks, the baby is busy stretching in the mother's belly all day long, stretching his arms and kicking his legs, and your abdomen often looks bumpy from the surface like a water ball. During this week, your baby's fingers and toes separate completely, and some bones begin to become stronger.

During this week, the organs that support the fetus' life have begun to work, such as the liver begins to secrete bile, and the kidneys begin to secrete urine into the bladder. Starting from this week, the baby's main task in the next 6 months is to grow strong and healthy, and prepare for independent survival after birth.
