How big is the fetus at 3 months old

The fetus can come out of the pelvis at 3 months. A normal fetus usually grows to 9 cm and weighs about 23 g. The fingers and toes can be basically separated, the bones are getting harder, and there are prototypes of joints and fingernails. The baby is very active at this time, lifting his legs or flexing and stretching his body, and can do various postures. The growth rate of his head is not as fast as other parts of the body. After 12 weeks of pregnancy, the baby slowly emerges from the pelvis, and you can see the pregnant woman's abdomen slowly bulging. Before 12 weeks, the baby usually has not left the pelvis and is still inside the pelvis, so the pregnant woman may not be able to see the bulge in her abdomen. At 12 weeks, the baby is getting bigger and bigger, and many pregnant women can touch the size of the uterus between the umbilicus and pubic area, and then they can communicate with the baby.

In clinical medicine, the number of weeks of pregnancy is calculated from the first day of the expected date of delivery. The whole process is about 280 days, with every four weeks as a pregnancy month, which is 40 weeks. Three months of nostalgia equals 12 weeks. At this time, the baby's biparietal diameter is about 1.7 cm, the baby's head circumference is about 6.8 cm, the fetal abdominal circumference is about 4.6 cm, and the femur length is about 0.7 cm. The fetus is about 9 cm long and 6-7 cm long from top to bottom. At this time, the baby's gender can be basically determined from its reproductive organs, and the baby's limbs can still move.

The body length of a 3-month-old fetus is about 9cm, and the length from top to bottom is 6-7cm. The third month of pregnancy has reached the late stage of pregnancy. The fetal reproductive organs can be basically distinguished, and the limbs begin to move. Pregnant women generally cannot feel the fetal movement, but can touch the fundus of the uterus through the ischial tuberosity. Pregnant women with thin abdominal fat can use Doppler to listen to the fetal heartbeat through the abdomen. Pregnant women with abnormal menstrual cycles can do color ultrasound. It is more accurate to calculate the expected date of delivery based on the fetal crown-rump diameter. After March, the baby develops rapidly, and pregnant women need a balanced nutrition, increase protein food every day, eat more fresh fruits, and supplement a variety of nutrients, minerals and other nutrients.

During the third month of pregnancy, the fetus is as big as your fist. At this time, the fetus has no fetal movements. If there is no early pregnancy reaction and no feeling at all, the pregnant woman may feel confused and not know whether she is pregnant or not. The best time to do a NT test is in the third month of pregnancy. If the NT test shows that the baby is normal, you must do all kinds of tests during pregnancy. At three months of pregnancy, that is, at 12 weeks of pregnancy, the size of the fetus reaches 65mm. During this time, the baby's fetal movement can be seen through ultrasound examination, but the pregnant woman cannot feel it.
