How big is the fetus at four and a half months of pregnancy?

When a pregnant woman is four and a half months pregnant, it means that she has entered the second trimester. Some early pregnancy symptoms will gradually disappear. At the same time, the pregnant woman's appetite will gradually increase to ensure the nutritional supplement of the fetus. Some fast-growing fetuses can feel fetal movements at this time. This is definitely a wonderful process. How big is the fetus at four and a half months of pregnancy?

The fetal length is 2 to 9 cm and the fetal weight is 9 to 23 g. The cheeks, jaw, eyelids and earlobes have developed and the face looks more like a human face.

9 weeks pregnant: The fetus is about 2cm long and still very light, about the size of a grape. The fetal head is larger than the fetal body, each part appears clearer, the skull begins to calcify, and the placenta begins to develop.

10 weeks of pregnancy: The baby is about 4cm long, the head-to-hip diameter is about 3-5cm, and the weight is about 13g.

11 weeks of pregnancy: The fetus grows to 6cm, the fetal organs develop further, and the placenta develops. B-ultrasound showed that the gestational sac had completely disappeared and the placenta was clearly visible.

12 weeks of pregnancy: The fetus grows to 9cm and weighs 23g.

At this time, the baby's tail has completely disappeared! It has already taken human form, and its growth rate is becoming more and more amazing. The body and legs have grown, but the head is still obviously larger. More importantly, the nose, gums, and vocal cords have grown, and the face can be recognized. The fetus' fingers and toes are completely separated, and the eyes, fingers and toes are clearly visible. Some bones begin to harden, and hair and nails begin to grow.

The fetus's skin is still transparent, so the subcutaneous blood vessels and internal organs can be seen from the outside. Organs such as the heart, liver, and stomach develop more fully. At this point, the shape of the external genitalia has been formed, but the gender cannot be clearly determined. Keep the secret until the baby is born, and you can reveal it yourself!

Warm reminder: Regular physical examinations are very necessary, not only to observe the physical condition of pregnant women, but also to test the health of the fetus. During the entire period of pregnancy, the food that pregnant women eat should be tasty and cooked in a variety of ways, while minimizing the loss of nutrients.
