Doctor's answer:
At 6 weeks of pregnancy, the embryo's spine and brain begin to form, the heart starts beating, and the embryo and heart activity can be detected with ultrasound. At this stage, the pregnant woman may experience early pregnancy symptoms. After 7 weeks, the limbs begin to form. By 8 weeks, the embryo has eyes but lacks a face and external ear canals. The embryo starts to move, but the pregnant woman cannot yet feel it. At 12 weeks, the fetus is about 7 centimeters long and weighs 20 grams, taking on a human-like shape. The head appears relatively larger compared to the rest of the body. The fetal heartbeat can be heard with a Doppler stethoscope. The fundus of the uterus can be felt above the pubic symphysis through the abdomen.
