At 17 weeks’ gestation, a bulge in the abdomen can be seen from the shape of the uterus, which lies between the navel and the pubic symphysis when lying down. After 12 weeks of pregnancy, the enlarged uterus gradually extends beyond the pelvis, and at 17 weeks of pregnancy, the abdomen is already visible as a bulge. At the time of the pregnancy test, the uterine fundus is between the navel and the pubic symphysis. At this time, the fetus is about 16 cm in length, 12 cm in parietal length, and weighs about 110 g. The fetal cephalic region is hairy, and the skin is thin, with no subcutaneous fat. The fetus has begun to show respiratory movements. At 17 weeks of pregnancy, some pregnant women can feel fetal movement, while others need some time to feel it. At this time, the fetal heartbeat can be heard in the abdomen using a fetal heart stethoscope, and the pregnant woman can monitor the intrauterine condition of the fetus through the fetal heartbeat and fetal movement.
